After the peach is picked, how to manage the fruit trees to ensure the high yield in the coming year? The management of the tree after the peach is picked is very important, mainly including pruning, cleaning the garden, disinfecting, fertilizing and strengthening the tree.
After pruning and pruning peach fruit, most of the leaves have aged, which is not conducive to the formation of flower buds. Therefore, the canopy should be renewed after fruit picking, that is, the main branch should be re-determined according to the tree shape requirements, the original backbone branch should be retracted to the new main branch position and the angle of the main branch should be adjusted, while competing branches should be eliminated and the main branch should be extended uniaxially. ; No auxiliary branches, if there is space, the auxiliary branches can be cultivated into a branch group; the result branch group is retracted to one or two branches at the base, or all are removed and re-cultivated.
Pruning is best done in two times. The first time is carried out immediately after fruit picking. Only the auxiliary branches, competing branches and upright branches are removed. The main branches, center trunk and large branches are properly cut off. The other branches are not cut, and the leaves are kept to raise trees. After 10 to 20 days, make further adjustments according to the growth of the tree to prevent the one-time heavy shearing from affecting the development of the tree.
Qingyuan disinfection combined with pruning. To clean the peach orchard, the branches, leaves, fruits and weeds should be completely removed, away from the burnt peach orchard, and never buried under the tree. At the same time, 50-60 kilograms of lime are scattered on the ground per mu to sterilize and sterilize the soil. It is also possible to spray the trunk and main branches with a 1-degree stone sulfur mixture 500-800 times, which is beneficial to prevent diseases and pests.
After fertilizing and strengthening the fruit, the fruit is collected and combined with weeding and weeding in the orchard. The amount of fertilization depends on the tree. Peach trees with many fruits and large nutrient consumption should be applied early and reapplied. Generally, the initial fruit trees of 3 to 5 years old can be properly fertilized. For the large fruit trees of 6 to 15 years, the amount of chemical fertilizer (composite fertilizer) is as follows Calculate the application of 1 kg per mu of 10 kg of peach.
