The Mengyin Peach Market, built in the Tang Dynasty, and the Mengyin Yingxian Bridge, built in the Ming Dynasty, have stone carvings of peach trees, which reflect the history of peach tree cultivation. The high quality, high yield and long-lasting quality of Mengyin peaches are related to their long historical roots.

After the founding of New China, Mengyin Peach has experienced three development periods. The first period was from the founding of New China to the mid-1980s. In a period of slow development, the main varieties are April Half, May Red, Shanghai Honey, etc. Mengyin County introduced Hanlu peaches and formed a scale in Daigu and Jiuzhai, becoming the origin of the rapid development of Mengyin County peach varieties. The second period was from the late 1980s to the mid-1990s, which was a period of rapid development. The area increased from 67 hectares in 1980 to 1,900 hectares in 1995. The third period is from the late 1990s to the present, which is a period of rapid development on a large scale. In 1995, Mengyin County became the first peach-producing county in Linyi City. By 2003, the area increased by 570.3% and the output increased by 425.6%. The area reaches 33,000 hectares and the output reaches 840 million kilograms, ranking first among the peach-producing counties in the country.

In 2002, the Mengyin County Party Committee and County Government actively created a pollution-free fruit production base of 300,000 acres throughout the county, including 150,000 acres of peach area. In November 2004, it successfully passed the inspection and acceptance of the pollution-free fruit production base in our county by experts organized by the Ministry of Agriculture. Our county was determined to be a national pollution-free agricultural product (fruit) production demonstration base county, and the quality and efficiency of Mengyin peaches were further improved. "Mengyin", "Yimeng Six Sisters" and "Mengyuan" brand peaches sell well in fruit markets across the country. Brands such as "Mengyin" and "Yimeng Six Sisters" have passed the certification of pollution-free agricultural products.

(2) Variety selection and specific requirements: There are more than 100 cultivated varieties of Mengyin peach, and nearly 30 have achieved large-scale production. Representative varieties: early The main mid-ripening varieties are Sako Zaosheng, Zaobaifeng, Hayakubo, Kurakata Zaosheng, and Shinkawa Nakashima; the main mid-ripening varieties are Zhaohui, Qiufengmi, and Laishanmi; the late-maturing varieties are Hanlumi, Beijing No. 9, and Zhonghua Shoudao. Lord. Peach accounts for more than 95% of the total output. With the establishment and development of the processing industry, the planting scale of processed yellow peach varieties has gradually expanded.

(3) Production process management, including agricultural inputs and production management.

Soil management: Deep plowing in winter to make the living soil layer reach more than 60 cm, hoeing frequently in summer to keep the soil loose; growing grass, mulching and burying grass in the orchard to improve the soil structure, increase the organic matter content and improve the quality of the soil. Fertility.

Scientific fertilization: Fertilization is mainly organic fertilizer, and the amount of fertilizer is 2 pounds per pound of fruit. Topdressing fertilizers are divided into three times. Chemical fertilizers are applied before germination, during the fruit expansion period and one month before harvesting. The fertilizers are mainly phosphorus and potassium fertilizers, and the dosage per mu is 15 kilograms. The use of nitrate nitrogen fertilizers and chloride fertilizers is prohibited.

Timely irrigation and timely drainage: Determine the irrigation time according to the season and soil moisture content. Irrigate according to soil moisture before germination, after flowering, and hard core stage. Fill with frozen water in early winter. Use as little water as possible before harvesting for late-maturing varieties. , to prevent fruit cracking. The roots of peach trees are afraid of waterlogging, so pay attention to timely drainage during the rainy season.

Reasonable shaping and pruning: Tree types usually adopt natural happy type, delayed happy type, Y type and other tree types. Pruning in winter is mainly based on sparing branches and growing them, with appropriate retraction and short cuts to restore the tree's strength. In summer, dense branches and long branches should be thinned out to improve ventilation and light transmission and color the fruits.

Flower and fruit management: Artificial pollination is carried out during the flowering period. Varieties with low fruit setting rates, such as Kurakata Zaosheng, Hayakubo, Kawanakajima and other varieties, are artificially pollinated to increase the fruit setting rate. Thin the flower buds before flowering, thin the fruits two weeks after flowering, and set the fruit after physiological fruit drop. The distance between large fruits and fruits is 15-20 cm, and the distance between small fruits and fruits is about 15 cm. All mid- to late-maturing varieties should be bagged from late May to mid-June, and the bags should be picked about 20 days before harvest.

Integrated pest control: Use artificial, physical, and biological measures to control pests, reduce the number of chemical pesticide applications, and fully protect natural enemies. It is strictly prohibited to use highly toxic and high-residue pesticides, promote the use of low-toxicity and low-residue pesticides or biological pesticides, and control the number of sprays to about 5 times during the growing season.

Timely harvesting, grading packaging, preservation and transportation: timely harvesting according to the characteristics of the variety, grading and packaging before listing or cold storage before pre-cooling.

The packaging materials must be clean, hygienic, non-toxic and odorless, and the variety, place of origin, trademark and pollution-free agricultural product logo must be indicated before export.
