Deeply turning the tree plate, expanding the hole, and renewing the root system is the key to transforming the "small old tree." Before the fruit picking to the deciduous leaves, at the same time as applying the base fertilizer, the deepening of the deep-expanding point should be grasped, combined with the expansion of the hole, the apex roots should be cut, the new roots should be cut, the organic fertilizer should be applied after root cutting, and the soil should be buried immediately. . Irrigation and conservation should effectively strengthen underground water and fertilizer management, do a good job in irrigation and conservation, pay attention to the application of basic fertilizer, and trace nitrogen fertilizer. Because the roots of "small old tree" are aging, the number of capillary roots is small, and the absorption function is poor. In particular, it is necessary to grasp the topdressing, irrigation and conservation work before the new shoots are prosperous. Such as the coating rod, spraying foliar fertilizer, etc., can promote the new roots to prosper and promote new roots. Prevention and control of pests and diseases Before the fruit picking, the whole fruit is sprayed 2 to 3 times, 70% of the mites are 3000 times or 20% of the acetamiprid 6000 times, mainly killing the spotted wax mites, tea-winged mites, small beetles, and aoculum. Pests and other pests. After harvesting the fruit, spray 20% leaf cumin 500-600 times solution or 20% thiabendone 600 times solution or 15 million units of agricultural streptomycin 1000 times solution, or spray 0.15 梧 éœ‰ç´ 800 800 800 times The leaves, branches and stems of kiwifruit are sprayed alternately, sprayed once every 10 to 15 days, and even sprayed 2 or 3 times to prevent kiwifruit ulcer disease.

After scientific fertilization and fruit harvesting, before the leaves, a sufficient amount of base fertilizer is applied to change the past practice of “depending on luck, relying on the sky, relying on nitrogen fertilizer and diamineâ€. Before June, the composition of nitrogen should be highlighted to promote long-term, long-leaf, and long trunks of trees. In July and October, it is important to apply phosphorus and potassium fertilizers to promote fruit growth. The basic fertilizer of autumn application should be all-element fertilizer, with long-acting and slow-acting organic fertilizer, quick-acting effect of chemical fertilizer, synergistic effect of mineral fertilizer, and special effect of microbial fertilizer to ensure the germination and longevity of kiwi in the coming year. The need for tipping, flowering, pollination, and fruit setting. In addition, it is necessary to increase the content of humus in the soil, timely supplement the medium and trace elements, and highlight the content of zinc.
Scientific flowers and fruits should be used for trees with severe aging. It is necessary to leave less flowers, less fruits, or leave no flowers or leaves. Try to avoid wounds on the backbone branches, especially to avoid causing large wounds. Weaken the growth potential of the tree, which is not conducive to the healthy growth of the tree.
Scientifically pruning serious, reasonable and scientific summer shears, autumn shears, winter shears, and promoting control. When pruning the tree, choose the moderately weak branches; when pruning the weak tree, choose the moderately strong branches; update the rebuilding and strengthening of the resulting branches in time, and implement the “three-three system†pruning method, that is, retain a result. Branches, cultivate a next year's reserve branch, and maintain a vegetative shoot.
Kiwi "Little Old Tree" Update Rejuvenation Six Measures
There are a lot of kiwifruit gardens. From the time when the seedlings have just been planted to the grafting, they have been growing unhappy and not energetic. A considerable part of the kiwifruit tree has just entered the initial fruit stage, and there is an early aging phenomenon, that is, the leaves are small, the branches are short (mostly aging or self-sealing branches), no new branches, no new leaves, no knots The fruit is not inflated, and the fruit of the whole tree is a "small egg." The formation of "small old trees" is mostly caused by poor quality of seedlings, shallow planting, improper selection of garden sites, etc. To improve the rejuvenation of "small old trees", the following measures should be taken:
