How to plant water chestnuts after harvesting early rice to achieve high yield?

According to the biological characteristics of horse hoof, it can be transplanted at any time from Qingming to Xiaoshu. However, in order to obtain high yields from horse hoof, it is advisable to start cultivating seedlings between Qingming and Xiaoshu. It is better to plant them early, and the transplanting time should not exceed the summer heat at the latest. This allows the plants to tiller and branch from the summer solstice to the Great Heat. Harvesting begins in late October, and the peak harvest period is from late November to late December.

The ones that start sprouting from Qingming to Grain Rain are called Zaoshui Horseshoes; the ones that start germination before and after the Summer Solstice are called Fushui Horseshoes; the ones that start germination from Minor Heat to Great Heat are called Wanshui Horseshoes. Preparing the land and applying basal fertilizer

Before and after Xiaoman, the field is plowed, usually 3 to 4 times, to make the soil into a paste. During the last plowing, basal fertilizer is applied. Horse hooves are more resistant to fertilizers and require the application of a sufficient amount of base fertilizer combined with quick-acting fertilizers. Generally, 80 kilograms of amino acid organic and inorganic compound fertilizers are applied per 667m2. Horse hooves are propagated by bulbs. The seeds of horse hooves overwintering in the field should not be dug up too early. They are usually dug out during germination and seedling cultivation. Before sowing, they should be selected one by one with good seed quality, large bulbs, high seed shape, sound terminal buds and side buds, and no pests and diseases. , bulbs without rotten wounds are used as seeds. The amount of planting required for each 667m2 field: 75-100kg of water chestnuts and late-water horseshoes, and only 15-20kg of early-water horseshoes, depending on the planting period. Cultivating short, strong and strong seedlings is the basis for high yield and high quality of horse hoof. Seedlings are generally raised between Qingming Festival and Grain Rain. Because the temperature in early spring is low and the seedlings emerge slowly, the seedlings should be germinated and raised 30 to 45 days before planting. The water chestnut seeds are dug up before the spring equinox germinates. After germination indoors, the seedlings are usually raised in open dry rice fields. Seedlings can also be raised in open water rice fields.

Indoor germination method: Before sowing, soak the seed chestnuts with 500 times of 36% Bacteria Zhenqing No. 2 agent for 12 hours to disinfect the seeds and kill surface germs. Then spread wet straw on the ground, alternately stack the seed chestnuts in 3 to 4 layers on the straw, with the top buds facing up, and cover it with straw. Water 2 to 3 times a day to keep it moist. After 10 to 15 days , start to appear green, and when the buds are 1.5cm long, remove the grass covering and continue to water to keep them moist. After 20 days, the leaf-like stems begin to grow, and when 3 to 4 lateral buds sprout at the same time, they can be planted in the rice field. How to manage rice to achieve high yield?

Scientific fertilization management methods for high-quality and high-yielding rice. Rice fertilization is closely related to conditions such as variety, soil, climate, and planting methods. Different varieties, soils and cultivation conditions: the rice yield per kilogram of nitrogen varies. Calculating the total absorption of nitrogen, phosphorus and potassium by rice, a kilogram of rice per mu needs to absorb 16 to 25 kilograms of pure nitrogen and phosphorus. 8 to 15 pounds, potassium 8.3 to 38.2 pounds, and the actual amount of fertilizer is generally more than the total amount of nutrients. Fertilization period has a certain impact on yield components. Generally speaking, basal fertilizer has a promoting effect on the number of grains per panicle and seed setting rate, but has little effect on the number of panicles per acre. Top dressing during the splitting period plays a major role in increasing the number of panicles per acre. Fertilization during the differentiation period of the cob is beneficial to the second branch. The differentiation and growth of the spikelets are greater, and fertilization during the spikelet differentiation and meiosis stages can prevent spikelets from degenerating and increase the number of spikelets per acre. Fertilizing before and after heading can increase seed setting rate and grain weight. Although there are many methods of fertilization, they must be adopted according to specific conditions.

"Promote in advance, control in the middle, and supplement later" method. For early rice fields where the base fertilizer is not very sufficient, there are not many basic seedlings, and the division period is short, top dressing can be applied again in the early stage of division, so that it can set up a high-yield frame as soon as possible in a relatively short period of time. In the middle growth period, appropriate measures should be taken to monitor the seedlings. If the seedlings are growing weakly, appropriate fertilizers can be added. If the seedlings are growing normally or too vigorously, appropriate measures should be taken to control the growth of ineffective divisions and promote the robust growth of effective divisions. Since this type of rice field does not have sufficient base fertilizer relay, it is easy to control in the mid-term and will not cause excessive growth in the later period due to heavy fertilization in the early stage. In the late growth period, appropriate supplementary application of ear fertilizer and grain fertilizer is required.

"Stabilize in the front and attack in the middle" fertilization method. On the basis of stabilization in the early stage, increase the amount of top dressing in the mid-term to attack the large ears, and in the later stage, seedlings will be supplemented with "flower-preserving" and "grain-increasing" fertilizers.

This method of fertilization is based on the establishment of a sufficient number of total seedlings during the division period. Fertilizer is mainly used in the early stages of young panicle differentiation (that is, the first bract differentiation and cob differentiation stages) to promote the differentiation of the second branch and stem. The spikelets are differentiated to increase the number of grains per panicle to achieve high yield.

"Smooth" promotion of fertilization method. On the basis of applying sufficient base fertilizer, fertilize steadily during the rice growth period. It is more suitable for early and mid-season rice. For early and mid-season rice, on the basis of strong seedlings and sufficient seedlings, it is not advisable to apply too much fertilizer during the splitting period, but should be applied early and steadily. Do not use too much fertilizer after the peak splitting period to make the splitting grow steadily. Pay attention to the application of ear fertilizer in the later period. , improve grain setting and grain weight.

The purpose of the "smooth" fertilization method is to prevent the rice from absorbing too much fertilizer at one time and lacking nutrition at the same time, so that it will be in a state of "smooth" fertilization throughout its life. Grow and develop in a nutritional state that is neither too deficient nor too vigorous.

When fertilizing rice, in addition to appropriate water slurry management and other measures, we must also pay attention to the coordinated use of various fertilizers. First of all, we must pay attention to the coordinated use of nitrogen, phosphorus, and potassium. Applying more nitrogen fertilizer can generally increase rice yield, but for high-yielding fields, too much nitrogen is often fixed, causing various elements to lose balance, and its yield-increasing efficiency is greatly reduced. Therefore, a certain amount of phosphorus and potassium fertilizers must be used to achieve the expected yield-increasing effect. At the same time, attention must also be paid to the combined use of organic fertilizers and inorganic fertilizers. Inorganic fertilizers generally have high active ingredients and fast fertilizer effect, but the fertilizer supply time is short; while the advantage of organic fertilizer is that it has a variety of fertilizer elements in the water content, the fertilizer supply time is long, and the fertilizer supply time is slow. If the two are used together, they can complement each other's strengths. How to grow wheat to achieve high yields

As the saying goes, if the farmer doesn’t use manure, it means you are fooling around. Before planting wheat, the ground should be fertilized with organic fertilizer. There should be no shortage of water during the growth period to achieve high yield. How to grow corn to achieve high yields

Corn plants are tall, require large amounts of water and fertilizer, and are not tolerant to waterlogging. Therefore, it is best to choose fertile soil with loose soil, permeability and good drainage for planting corn. Although sandy soil has good permeability, it has poor fertility and weak water and fertilizer retention capacity; clay soil has poor permeability, poor soil preparation quality, and is difficult to cultivate. The ideal soil is loamy soil. In addition, corn has weak salt tolerance. When the total salt content of the soil in the entire cultivated layer reaches 0.41 and chloride ions reaches 0.061, the growth will be poor. Therefore, soil with heavy salinity needs to be improved. How to grow vegetables with high yield?

1. Study market trends. Vegetable farmers can go to nearby vegetable wholesale markets or farmers' markets. If conditions permit, they can also go to vegetable wholesale markets in large and medium-sized cities to investigate and learn about the sales of various vegetables, or hire experienced vegetable dealers as production consultants to keep up with the situation. Market, implement planned production of vegetables according to market needs, and reasonably match varieties and quantities.

2. Select new varieties. The new varieties are popular for their high quality, high yield, disease resistance and adaptability. Actively selecting new varieties according to market demand can achieve good returns. However, farmers are reminded that they must go to formal seed management departments to purchase approved seeds. In addition, before introducing seeds across regions, you can first consult with the agricultural technology extension department to find out whether they are suitable for the local climate conditions; if the seeds can be introduced, a small amount of seeds should be introduced for trial planting first, and then the area can be expanded after a certain consumer market is formed.

3. Promote pollution-free cultivation. In order to meet consumers' demand for pollution-free food, vegetable farmers should proactively adopt pollution-free cultivation techniques and implement standardized production in production. If you do not use highly toxic and high-residue pesticides, apply more organic fertilizers, bio-fertilizers, bio-pesticides, etc. It is necessary to actively register trademarks for vegetable products and establish brand awareness. Those who have the conditions should implement pollution-free agricultural product certification as soon as possible to seize and expand market share.

4. Improve technological content. For example, greenhouse cultivation uses drip-free longevity film, two-layer thermal insulation film, reflective curtain, sunshade net, insect-proof net, implements drip irrigation and infiltration irrigation, applies biological bacterial fertilizer, carbon dioxide gas fertilizer, uses bees for pollination, etc., and increases technology in production. content, can achieve twice the result with half the effort.

5. Do a good job in three-dimensional planting. Three-dimensional planting can rationally utilize time, space and soil nutrients, and improve the multiple cropping index.

For example, spring cucumbers are intercropped with oyster mushrooms, summer beans are intercropped with straw mushrooms, watermelons are intercropped with bell peppers, luffa, chayote, and pumpkins are planted on the scaffolding, coriander, Chinese cabbage is planted under the greenhouse, and shepherd's purse, Chinese cabbage, and spinach are planted under the fruit trees. The potential for increasing income is great.

6. Plant specialty vegetables. Specialty vegetables are unique because of their small cultivation area and high commodity value. They can be first introduced and tested according to local conditions, and then further expanded. Such as bulb fennel, chicory, Brussels sprouts, super sweet corn, vegetable sweet potatoes, fruit radishes, dandelions, etc. How to grow horse hoof fungus?

How to grow calla lilies? -------------------------------------------------- --------------------------------

Techniques for indoor cultivation of calla lilies 1. Choose a diameter of 25 Centimeters and above flower pots. Before potting, you should prepare culture soil with high organic matter content and good drainage efficiency, as well as high-temperature fermented cake fertilizer and paclobutrazol. Plant the plants, use 0.5g of paclobutrazol, add a small amount of fine soil and mix well. 2. Calla lilies should have sufficient fertilizer and water during the growth period. Fermented liquid fertilizer should be applied every 7-10 days to promote growth and flourish the flowers. If there is insufficient fertilizer, the stems and leaves will turn yellow, affecting flowering. Potted flowers should be placed in a moist, shaded and well-ventilated place. When the weather is dry and hot, you can spray water on the leaves and around the potted flowers to cool down and increase humidity, while also keeping the leaves fresh and clean. The appropriate growth temperature is 15-20°C. The following spring, the dwarfed plants will bloom with beautiful, white flowers. After cultivation comparison, plant growth regulator was used, and the root treatment effect was good. The treated calla lily plants are obviously dwarfed, with a plant height of about 28 cm (the untreated one is about 54 cm); the leaves are large and thick, 29 cm long and 18 cm wide (the untreated one is 20 cm long and 13 cm wide); It has high brightness, blooms early, and the flowers are higher than the leaves (the untreated flowers and leaves are basically flush); the flowering period is long, and the flowers are strong and numerous.
