Jiaozhou City is located on the bank of Jiaozhou Bay, bordering Jimo City to the east, Chengyang District of Qingdao City, Pingdu City to the north, Gaomi City to the west, and Gaomi City to the southwest. Zhucheng City borders Jiaonan City in the south. In February 1987, Jiaozhou City took the lead in removing counties and establishing cities in Qingdao. It was one of the first coastal cities in Shandong Province to open up Jiaozhou Dabaicai

. The city currently governs 13 towns and 5 sub-district offices, with a total area of ??1,210 square kilometers and a total population of 780,000. By the end of 2005, Jiaozhou City had an urban population of 280,000 and a built-up area of ??nearly 40 square kilometers. Jiaozhou city has a superior location and developed transportation. Jiaoji, Jiaohuang, and Jiaoxin railways traverse the territory, and Jiqing, Jiaozhou Bay, Tongsan, Qinghong expressways, and 204 National Highway crisscross the territory. Jiaozhou is 35 kilometers away from Qingdao Port, 30 kilometers away from Huangdao Qianwan Port, and 25 kilometers away from Liuting International Airport. There is the third railway container marshalling station in the country, which is the throat of the peninsula and an important transportation hub. Jiaozhou is located on the bank of Jiaozhou Bay. The special geographical environment and natural conditions have created unique biological species, making the local area rich in agricultural resources. Jiaozhou has a mild climate, distinct four seasons, rich products and splendid culture. The abundant Jiaozhou cabbage is famous both at home and abroad.

Edit the cultivation techniques of this section

The sowing period of spring Chinese cabbage is very important. Sowing too early and the outside temperature is too low are not conducive to germination, emergence and growth of seedlings, and the seedlings will take a long time. Being at low temperature is conducive to bolting. If sown too late, the temperature in the later period will be too high, which is detrimental to ball formation. Therefore, the sowing period should be strictly controlled according to the prevailing climatic conditions.

The principle is that the appropriate sowing period is 15 days before the date when the daily average temperature reaches 13°C. That is to say, after sowing, the Chinese cabbage will not grow for more than 15 days when the daily average temperature is below 13°C, and it will not easily occur. The phenomenon of bolting before the balls form.

Drill deep ditches for live broadcast and cover them with mulch

(1) Ditching: Open a ditch 15 cm deep on the plowed 1-meter-wide border. If the soil moisture is good, you don't need to water; otherwise, pour enough water in the ditch. (2) Spread seeds: Spread seeds evenly in the ditch to make the seeds as thin as possible. The seeding amount should be less than that used for autumn sowing, but it should be evenly distributed so that there is no need to thin out the seedlings until they have grown to 3 to 4 leaves after emergence, and the seedlings will not be too dense to affect growth. After sowing the seeds, cover the trench with 1 cm thick soil and pat it lightly. (3) Cover with mulch: Open shallow ditches on both sides of the border, cover with mulch, and compact it with soil. Pay attention to tightening the surroundings so that the Chinese cabbage will be in an environment similar to a small shed after emergence.

Seedlings and Transplanting

In order to avoid the adverse effects of external low temperature, greenhouse seedlings can be grown if conditions permit, or Jiaozhou Chinese cabbage can be grown in Yangqi. Seedlings. In greenhouse seedlings, the temperature can be controlled manually and is less affected by the outside temperature, but it will still be affected by the low temperature outside after planting. Therefore, the sowing date should be determined according to the planting period and should not be blindly advanced. If the seeds are sown too early, the outside temperature will still be low when the seedlings grow to a size that can be planted. After planting, it will not only affect the growth, but also cause the Chinese cabbage to bolt early after experiencing a period of low temperature. Therefore, the sowing period must be strictly controlled. Under greenhouse conditions, it takes about 30 days from sowing to growing to 5 to 6 true leaves. Yangqi seedlings are greatly affected by the outside temperature. When determining the sowing period, in addition to considering the low temperature for a period of time after planting, it is also necessary to consider that the Yangqi seedlings will also be affected by low temperature during the cultivation period. The cumulative temperature of these two stages is below 13℃. The time should not exceed 15 days. Seedlings are raised in Yangqi from sowing to growing to 5 to 6 true leaves. It takes about 40 days. Sowing dates should be determined based on these factors.

Seedling setting and planting

(1) Seedling setting: For Chinese cabbage that is broadcast in trenches, after emergence, after a period of growth, the seedlings will appear too dense, especially This problem occurs earlier at higher seeding rates. Therefore, you need to do a thinning at this time. You can choose to uncover one side of the mulch film at noon on a sunny day, and thin the seedlings so that the distance between the plants is about 5 cm. After thinning, the mulch film should still be tightened and compacted. When the seedlings grow to the point where the upper leaf edge is close to the mulching film, holes can be punched in the film to let out air to prevent the seedlings from being burned by high temperatures at noon. After 5 to 7 days of exposure and exercise, when the seedlings reach 5 to 6 leaves, the film can be completely uncovered at noon and the seedlings can be fixed. The distance between the plants varies depending on the variety, generally 25 cm to 30 cm. When planting seedlings, pay attention to pulling out diseased seedlings, weak seedlings and miscellaneous seedlings. (2) Planting: When the seedlings of transplanted Chinese cabbage grow to 5 to 6 leaves, they can be planted after hardening. The planting density is the same as that of direct seeding, that is, the spacing between plants is 25 cm to 30 cm, and there are 2 rows per border.

Management after planting

During the time of seedling setting and planting, the outside temperature is still low. When pouring the seedling water or planting water, do not flood with water to avoid lowering the ground temperature. It can be watered lightly with light water. After 2 to 3 days, it can be watered lightly again, and then cultivated to maintain moisture, increase ground temperature, and promote growth. After entering the rosette stage, in addition to applying 150 kg to 225 kg of ammonium sulfate or urea per hectare (15 acres), special attention should be paid to the watering method. It is not advisable to squat the seedlings too much to inhibit growth. Therefore, there is less rainfall in spring, the weather is dry, and the soil evaporation rate is low. larger. After a certain period of squatting, water the seedlings in time and do a good job of cultivating and maintaining moisture. Entering the balling stage, the growth rate increases and a large amount of fertilizer is required. Fertilization must be carried out in a timely manner. Approximately 300 kilograms of urea or ammonium sulfate per hectare (15 acres) should be topdressed and watered in time. During this period, the outside temperature continues to rise. The prevalence of soft rot caused by high temperature and humidity should be avoided. Therefore, special attention should be paid to watering techniques. Watering can be done in the cooler morning or evening. Flooding should be avoided. Generally, every 2 Watering once every day to every three days can not only meet the water needs of the ball, but also reduce the ground temperature, and at the same time avoid the prevalence of soft rot.

Pests and diseases control

During the seedling stage of spring-sown Chinese cabbage, there are fewer pests and diseases due to low temperature conditions, but they cannot be completely ignored. Pay attention to observation and prevent and treat hidden dangers in time once they are discovered. In the late growth period, the temperature rises, which is conducive to the occurrence of pests and diseases, so special attention should be paid to prevention.

You can spray disease prevention and insecticide pesticides every 7 days. The pesticides used are the same as those used for autumn sowing.

Edit the production points of this paragraph

Strictly select production bases

Strictly select production bases in accordance with green food production requirements, and the environmental conditions of the place of origin meet NY 5010 requirements for Jiaozhou Chinese cabbage

Ask. The base is far away from industrial and mining areas, and there is no pollution in the air, irrigation water and soil. It requires flat terrain, convenient drainage and irrigation, deep soil layers, and good physical and chemical properties. Sandy loam, loam and light clay are suitable, and the soil fertility is high.

Cultivation measures

(1) Correct selection of varieties: Choose high-quality, disease-resistant, and high-yielding Chinese cabbage varieties. In order to ensure that the properties of Jiaozhou Chinese cabbage products are consistent and of high quality, the Jiaozhou Chinese Cabbage Association designated the special varieties for the Jiaozhou Chinese Cabbage Base as 87-114, the Autumn King of Jiaozhou Vegetables. Each base must apply designated varieties. (2) Reasonable land preparation and fertilization. After the previous crop is harvested, the fields should be cleaned. According to the fertilizer requirement pattern of Chinese cabbage, soil nutrient status and fertilizer effect, the corresponding fertilizer amount and fertilization method should be determined through soil nutrient testing. According to the principle of combining organic and inorganic, and combining base fertilizer and top dressing, balanced fertilization is implemented. The recommended fertilization plan is as follows: 1. 5000 kg to 6000 kg of high-quality decomposed organic fertilizer, 30 kg of Yunfeng brand potassium sulfate ternary compound fertilizer (15-15-15), and 1 kg of Fei Laoban (enzyme bacteria expansion agent); 2 , 100 kg of Diendi bio-organic fertilizer, 1 kg of Fei Laoban (enzyme bacteria expansion agent), and 30 kg of Yunfeng brand potassium sulfate ternary compound fertilizer as the base fertilizer. After plowing, harrow, level and raise the ridges. The ridge spacing is 75cm~80cm, the ridge height is 15cm~20cm, and drainage ditches are provided under the ridges. How to use Fei Laoban (enzyme bacteria expansion agent): Before the Chinese cabbage is raised, mix 1.0 kilograms of Fei Laoban with 50-100 kilograms of organic fertilizer or cake fertilizer, bean dregs, and bio-organic fertilizer, and then spread it in the middle of the furrow. It can also be mixed with Use a mixture of compound fertilizers. Then ridging. List of fertilizers recommended for base use: Microbial fertilizer: Fei Laoban (enzyme bacteria expansion agent) Organic fertilizer: Diendi organic fertilizer Bio-organic fertilizer: Diendi bio-organic fertilizer Inorganic fertilizer: Yunfeng brand potassium sulfate compound fertilizer (content: 45% ) (3) Sowing at the right time Sow at the right time according to the climatic conditions and variety characteristics of Jiaozhou City. Specified varieties should be sown 8-10 days after the beginning of autumn. Create moisture 2-3 days before sowing and implement hole sowing. Generally, the seeds are sown in the afternoon. After sowing, they are covered with 0.5cm to 1cm of fine soil, flattened and compacted, then covered with soil and cultivated into small mounds. After two days and nights, the mounds are removed at 4 p.m. The appropriate density is about 1800-2000 plants. (4) Field management 1. Time seedlings. Direct seeding and thinning of seedlings should be carried out four times. After the seedlings are unearthed, do this every 6 to 7 days. Leave 5 to 6 seedlings for the first time, 3 to 4 seedlings for the second time, 2 seedlings for the third time, and 1 seedling for the fourth time (fixed seedling). If seedlings are missing, they should be replanted in time. 2. Timely cultivating and weeding. Cultivating and weeding should be carried out three times before sealing the cabbage ridges. The first time is carried out 15 days after sowing, the second time is done 5 to 6 days after the seedlings are established, and the third time is done 15 to 20 days after the seedlings are established. During cultivating, the ridge surface should be hoeed shallowly to remove grass. 3. Reasonable watering. Germination period: After sowing, from the time when the seedlings are unearthed to when the young leaves are cross-shaped, if there is high temperature and drought, water should be watered once in time. When using the direct seeding method of Jiaozhou Chinese cabbage

, the watering amount should be based on the principle of half furrow water; when using the seedling raising method, the watering amount should be based on the principle that the bed soil does not dry out and is kept moist. Seedling stage: From the time when the young leaves are cross-shaped to the formation of 8 leaves, when using the direct seeding method, water once after each thinning, and the amount of watering is based on half the furrow water; when using the seedling method, water 2 to 2 months before transplanting Water once every 3 days, the amount of watering should be based on keeping the bed soil moist. Rosette stage: After applying the rosette fertilizer, water once. The amount of watering should be based on the principle of filling the furrow with water. The principle of watering after that is that the ground is dry before watering again. Balling period: When applying the first balling fertilizer, water once, and then every 5 to 6 days. The amount of watering should be based on the principle of filling the ridge and furrow with water. Stop watering 7 to 10 days before harvest. 4. Timely fertilization. Rosette stage: After the seedlings are established, when the seedlings grow to 8 to 10 leaves, start applying rosette fertilizer. Apply 1500 kg of decomposed organic fertilizer or 10 kg of nitrogen, phosphorus and potassium compound fertilizer between the plants every 667 m2.

Ball-bearing period: Topdress twice during the ball-bearing period. For the first time, when all the rosette leaves have grown up and the young bulbous leaves in the center of the plant have curled cores, apply 8 kg of compound fertilizer in the ditch between the rows every 667 m2. After 15 to 20 days, perform the second topdressing. Apply nitrogen along the water every 667 m2. Phosphorus and potassium compound fertilizer 10 kg. 5. Prevent and control pests and diseases in a timely manner. Adhere to the principle of prevention first and comprehensive prevention and control, giving priority to agricultural control, physical control, biological control, and scientific and reasonable chemical control.

Chinese cabbage is a must-have on every table at the New Year's Eve banquet, which means "vast wealth brings in hundreds of fortunes". The most expensive Chinese cabbage is a huge jade cabbage that appeared at the 2nd China (Changchun) Folk Art Expo. It sells for 228,000 yuan, which is really the first of "a hundred fortunes". It is said that after the notorious thief Yuan Shikai proclaimed himself emperor as Emperor Hongxian in the winter of 1915, he suddenly remembered that he had eaten Jiaozhou cabbage once when he was following the Queen Mother of the West. It was so delicious, so he ordered the Ministry of Internal Affairs The head of the department, Zhu Qiqian, quickly sent people to Jiaozhou to bring Jiaozhou cabbage to Beijing for a feast. Local officials received the order from the peak and immediately ordered the collection of Chinese cabbage. At that time, seven points of land in Sanlihe had been assigned to the descendants of Gao Fenghan. According to the genealogy of the Gao family, "Wei Ye Hui Fang Zhen, Yi Si Xu Yu Xing", it had been passed down to Gao Fanglin of the Fang generation. Gao Fanglin, an old man who understood justice deeply, hated Yuan Shikai's restoration and proclaimed himself emperor, but he had no choice but to take his whole family to slowly select from the harvested cabbage. Yuan Shikai was probably destined not to eat this Jiaozhou cabbage. Just when the Gao family finally collected the amount of cabbage forcibly sent by the government and were waiting to be transported to the train station, God suddenly changed his face and the temperature dropped sharply. , the cold wind suddenly appeared. Yesterday it was still warm and sunny, but it seemed to become extremely cold in an instant. The sharp northwest wind rushed towards us with the shocking cold, like a cold sword made of ice and cold air, bringing it with it. The sound of shrill howls slashed and slashed wildly in the air. The sun seemed to have been sucked away by the severe cold and all its temperature had been sucked away. It was like an empty ball with no temperature hanging in the air in name only, despite this icy cold sword. It waved the cold wind all over the sky to do whatever it wanted, tearing off all the clothes on the surface of the human body wantonly, and forcefully pouring biting cold wind into the human body, making people feel that this coldness is generated from the inside out, so it is cold. It turns out that the local old people call this wind the "bone-eviscerating wind". This is the severe cold weather that has not happened in Jiaozhou for a hundred years. The officials responsible for escorting this batch of cabbage looked at the sky and sighed with tears. They could only watch helplessly as the Chinese cabbage that had been loaded onto the truck and ready to be transported was frozen under the ravages of the severe cold. It was as hard as a rock and turned into a pile of feed that was inedible and could only be fed to pigs. Because of a sudden severe cold, Yuan Shikai, an old boy, could not get a bite of the Jiaozhou cabbage he dreamed of. In June of this year, before the cabbage was even planted, he died and drove his donkey west. It will become his lifelong regret!
