In the autumn, nectarines should also be strengthened after harvest to supplement the tree's nutrition. Because of the growth and development of fruit trees in the next year, including germination, leaf spreading, branching, flowering, and fruit setting, most of the nutrients needed come from nutrients accumulated in this year's trees. The accumulation of nutrients in the tree is insufficient. Nectarine autumn management pay attention to six:
First, pruning and pruning should be carried out in time to eliminate the dense branches, thin and weak branches, and useless erect branches, overlapping branches, cross branches, and old and weak branch groups. The retraction should be performed for the strong Wang branches or branches of the upper part of the canopy. Sprains and pressures from the base; upright branches with competing branches and space retention are sprained or pressed to control growth and promote flower bud differentiation, which is beneficial to the results. At the same time, the late autumn shoots are plucked and the branches mature.
Second, to prevent pests and diseases in the autumn can be sprayed with 400-500 times more antibiotics and Diflubenzuron 3 2000 times the liquid, control of leaf diseases and pests, reduce early leaf loss, improve photosynthetic efficiency.
Third, it is necessary to sort out the tree plates, timely prevent floods from combining with cultivating and weeding, and organize the tree plates into the form of inner high and low outer, to prevent water accumulation in the tree trays, and to dig wells for low-lying orchards.
Fourth, the autumn basal fertilization “early, full, full, and wide†is mainly applied to high-quality organic fertilizers, and appropriate amount of nitrogen, phosphorus, and potassium ternary compound fertilizers. The amount of fertilizer varies from tree to tree. In general, less trees are used and weak trees are used more. The yield of fertile trees is 2 to 3 times the yield. When fertilizing, trenches with a depth of 30 to 50 cm and a width of 50 cm are dug below the circumference of the crown, and the top soil and organic fertilizer are mixed and filled into the trenches to fill the surface with the earth and soil. The shallower orchards in the root distribution layer of the mountain can be applied to the 20-40 cm root distribution layer. In the nectarine garden with a large amount of fruit set, after the fruit is harvested, the leaves are supplemented with spraying, and potassium dihydrogen phosphate 300 times is generally sprayed.
Fifth, it is necessary to turn the tree in autumn. Many larvae and mites of overwintering pests are concentrated in the ground within 10 cm of the canopy and overwinter. After turning the tree, they can kill a group of pests.
Sixth, after burying frozen water into the winter, it is appropriate to irrigate the frozen water. According to soil moisture, the amount of water should be sufficient to wet the dry soil layer. Pouring frozen water should not be too late, not later than mid-November.![]()
