Anti-wilting kiwifruit leaves wilting during high temperatures in summer, mainly due to two points: First, high-temperature drought, mostly occurred in the sunny from noon to 4 pm, sooner or later, usually a large area. This situation should be promptly filled with water in the morning and in the evening, and wilting can be lifted. The second is root rot and root knot nematode disease in the root system, which causes the pathological wilting of the root system to be destroyed. At noon, the performance was most severe, and the duration was longer. In severe cases, symptoms were also manifested in the morning and in the evening. The symptoms were sporadic. Once it has been found that it should be rooted and checked, and it is indeed a pest, the branches and leaves should be properly cut off, some or all of the fruit should be removed, and the agricultural anti-120, fungicides should be used to irrigate the roots.

Prevention of sunburn is a common physiological disease in the summer of kiwifruit. In addition to preventive measures such as high-temperature irrigation, reasonable summer shear, appropriate leaf/fruit ratio, and control of fruit weight, two Merrill Lynch high-efficiency calcium sprays (15-20 days apart) were applied during the young fruit period, one by one for the exposed fruits. Bagging can also effectively prevent sunburn.

Anti-shade fruit trees during fruiting period, ignoring buds, partial application or reapplication of nitrogen fertilizer, trees are prone to shading. In the summer, the buds were lightly picked, and the second branch that germinated after the first topping was left with 3-4 leaves, and the three branches left 1-2 leaves for repeated topping. Turn on the light path and repeat the topping on the peripheral branches (outside the second to the wire) and the result branches 2-3 leaves to remove the vegetative branches. Slightly weak branches and temporary branches that occurred under the shelves were cut short and removed. Remove old yellow leaves. By adopting the above measures, a high-yield landscape featuring “no winding on the trees, a slit between the rows, a flower shadow under the tree, and sunlight on the branches” was achieved.
