After the Beginning of Autumn, fruit growers should prune the over-closed orchard branches in time, the main purpose of which is to improve the permeability and photosynthetic efficiency of orchards, increase the photosynthetic area of leaves, enhance fruit coloring and improve fruit quality. At the same time, parasitic branches and winding branches should be removed to keep the light distribution under the frame uniform. In addition, pruning should also be wet and should not be overweight, so as not to affect photosynthetic efficiency or cause sunburn of the fruit.

2. Water management

The temperature gradually turns cool after autumn, which is also the season when Rain Water is more concentrated, so it is more important to drain too much water in the park. Fruit growers should check the stagnant water in the orchard at any time, dredge the ditches, and reduce the damage to the root system due to stagnant water, high temperature and humidity. Especially in early autumn, if the temperature reaches more than 35 degrees, the dry and hot wind produced by the dry climate will often cause the leaf edge of kiwifruit to dry up and the fruit will be burned, so when it is hot and dry, it is necessary to water in time to keep warm and cool down.

3. Weeding

After entering the rainy season, the rainfall is concentrated, sufficient water will lead to the breeding of a large number of weeds, most fruit growers should timely control the weeds in the orchard, timely weeding, increase permeability, reduce humidity, reduce the probability of diseases and insect pests. The weeds can be covered with tree plate, increase the organic matter in the orchard after decay, improve the soil aggregate structure, and increase the water and fertilizer conservation capacity of the soil.

4. Pest control

After the beginning of autumn, kiwifruit is also a period of high incidence of diseases and insect pests, the main diseases and insect pests are soft rot, gray mold, bugs, leafhoppers and so on. If it is not controlled in time, it will not only cause fallen leaves and fruits, but also lead to fruit diseases during harvest and storage. Therefore, it is necessary to prescribe the right medicine according to the occurrence of diseases and insect pests, and choose triazole fungicides, 1000-fold solution of 80% methyl thiophanate wettable powder, puthulide and other agents for control according to the condition of the disease. Pests can be alternately treated with cyhalothrin 1500-fold solution or cypermethrin 1500-fold solution to avoid drug resistance.
