Peach trees were planted in mid-to-late March and managed according to conventional methods. To obtain a certain amount of production in the year of planting, it is necessary to adopt comprehensive technical management measures based on the growth characteristics of peach trees. The planting density of 1m 1m, 1m 1.25m or 0.81m is suitable for close planting. In the year, sufficient branches and flowers can be obtained, and the following year, higher yields will be obtained. After the plantation is closed, reasonable thinning will be carried out. Fertilizer management Before planting, dig 70-80 cm deep planting trenches. When digging trenches, separate the raw soil from the mature soil. Fill the grass at the bottom with 10-15 cm thick, then fill in 10 cm of mature soil, and press 667 on top. Apply 50 kg of organic fertilizer in the square meter, mix 5 kg of diammonium phosphate with the soil and fill it with water. Planted in mid-to late March, covered with plastic film. Repeatedly topping the tree to overwow the buds and plucking out the heart to promote the second branch and cultivate the main revolutionary tree with the central leadership. When the second branch grows to 20 centimeters, it is tossed again and promoted the third branch. Controlling the growth of phosphorus and nitrogen fertilizers to promote flower bud differentiation is generally from the end of June to early July, when the second branch grows to 0.25-0.3 meters, spraying 15% of paclobutrazol 300 times WP, to spray evenly, especially The tip of the new shoot must be sprayed. Insect pest control is generally based on proper pruning and trimming, and on the basis of ventilation and light transmission of the trees, the diseased fruit, diseased leaves and diseased branches are cut off, and the lime sulfur spray is sprayed 4-5 times before germination. When the pests occur, targeted sprays may occur. 2500 times the sweeping profit or 3000 times the mothworm spirit control leaf roller moth, red spider, stink bug and so on.
