With the development of breeding technology, very early peach (such as April peach, May crisp peach) and extremely late peach (such as snow peach, peach, winter peach) have appeared one after another, which will extend the peach fruit market supply period, increase peach Agricultural economic benefits create favorable conditions. However, in the actual cultivation of early-ripening peaches, early defoliation, flower buds, and large fruit production can easily cause premature aging tree vigor. The late-maturing and late-maturing peaches consume less nutrients in the early growth period, and the trees are rich in nutrients and grow too prosperous, resulting in serious fruit drop, which makes it difficult to cultivate and manage the fruit farmers. For example, in the late-maturing and late-maturing peach trees, the high-recognition and early-maturing peach varieties can achieve the purpose of combining the early and late ripenings, complementing each other, and high-efficiency. According to the author's experiment, using this technology, the second year peach trees can produce 4 kilograms of fruit (including 1 kilograms of early peaches and 3 kilograms of late peaches) in the third year up to about 15 kilograms, and the fourth year can yield large yields. Now introduce its cultivation techniques as follows: First, nurturing strong seedlings. Using the nectarine or nectarine planted in the same year as the anvil and late-maturing cultivars (such as snow peach, winter peach, holy peach, crisp peach, kilogram peach, and gold peach) as the scion, the "D" shaped bud connection method was applied to the peach in early June. Grafting in the stockpile. Through two anvil treatments, the buds germinate in the current year. When the buds grow to 50 cm, they are picked up or treated with paclobutrazol so that full shoots are formed in the plastic belt. Second, rational colonization. According to the specification of 2m or 4m or 3m and 4m, the planting ditch will be excavated, and after sufficient base fertilizer is applied, planting will be carried out in the early winter and early spring to prevent rooting. Diligent application of thin fertilizer fertilizer, then the planting of late peaches in May to June can form a crown more than 1 meter. At this time, the dichotomy between the inner pupa and the two trees adopts the "D" shaped bud to pick up the very early sweet peach. Cut off the buds on the buds (cut the buds more than 5 cm apart) and wipe off the buds of other buds on the shoots. Third, tree management after grafting. After grafting, the tree body was applied once with available Nitrogen Fertilizer. When the buds were grown to 40 cm, they were picked up, or the whole garden was sprayed with paclobutrazol. Drain the ditch, and do a good job pulling branches, hanging trees, twisting branches and control of leafhoppers, aphids and other work.
