Peach tree is a medium-sized tree, small, easy to cultivate and manage, and has strong adaptability to soil and climate.
Suitable rootstocks and varieties can be selected for cultivation in the south, north, mountains and plains. All kinds of flowering peaches, hanging peaches and longevity peaches suitable for potted viewing have played an important role in greening the city and beautifying people's lives. Peach originated in China and has been cultivated for more than 4000 years.
Peach tastes good, and the whole body can emit a pleasant fragrance, and it is rich in nutrients, which is beneficial to the body and can prolong life.
Peach branches, leaves and peaches also have medicinal value. Sun Simiao, a pharmacologist in the Tang Dynasty, called it "the fruit of lung" and said that "lung disease should be eaten". Traditional Chinese medicine calls the lungs "scorched viscera", which likes dampness and hates dryness. Peaches are rich in gum, which can absorb a lot of water in the large intestine and prevent constipation. The nutrition of peaches is very superficial. It is said in Daming Materia Medica that drying peaches and taking them regularly can play the role of beauty beauty. It's just that the sugar content of dried peaches is too high. It is much better to take boiled water with a small amount of green tea or herbal tea, and it can also improve the flavor.
cultivation techniques
Generally by grafting propagation. Its rootstocks are peaches in the south of China and peaches in the north. It is also useful to use this rhizome or plum, plum, apricot and cherry as rhizome. Seedling raising method is still used in some production areas. Cutting propagation of yellow peach in Australia was successful. Taoyuan is not suitable for continuous cropping. The planting distance is slightly south, about 33 ~ 40 plants per mu; It is slightly sparse in the north, with about 22 ~ 27 plants per mu. Cultivation of Prunus tomentosa in mountainous areas and dwarfing with rootstocks can increase the density. Generally planted in autumn and winter, planted in northern spring. Peach trees grow vigorously, so young trees should control the application of nitrogen fertilizer to avoid unnecessary growth. After entering the full fruit stage, the amount of nitrogen fertilizer can be increased, and phosphorus and potassium fertilizer can be applied together. In addition to applying base fertilizer every year, quick-acting topdressing should be applied after flowering, fruit expansion and harvest. When symptoms such as iron deficiency, zinc deficiency and boron deficiency are found, foliar fertilization should be carried out. Irrigation in autumn drought or spring drought in summer and frozen water in winter. Tillage is usually combined with irrigation and fertilization.
The common modeling method is natural and happy modeling to adapt to its light-loving characteristics. The pruning method depends on the variety, tree age and environmental conditions. In the growing season, summer pruning techniques such as sprouting, sprouting, coring, twisting, pruning and thinning should be adopted as far as possible to control the growth of branches, save nutrients and reduce the amount of pruning in winter. Updating the branches in time and reducing the number of peripheral branches after the full fruit period of peach trees can avoid the outward migration of some fruits and prolong the full fruit period. Proper thinning of young fruits 20 ~ 25 days after flowering is beneficial to ensure fruit quality and high and stable yield year after year.
