Key Points for the Latest Autumn Management of Kiwifruit Orchards
August-September is precisely the critical period for kiwifruit quality formation. At this time, fruit growers should carry out management measures well so that the variety and yield of kiwifruit can be improved. So how should kiwifruit orchards be managed in autumn? Follow the editor to learn about it.
1. Pruning of branches and shoots
After the Beginning of Autumn, fruit growers should promptly prune the branches and shoots of overly dense orchards. The main purpose of this is to improve the orchard's ventilation and light transmission and photosynthetic efficiency, increase the photosynthetic area of leaves, enhance fruit coloring, and improve fruit quality. At the same time, parasitic branches and twining branches should also be thinned out to keep the light distribution under the trellis uniform. In addition, pruning should be moderate and not too heavy, so as not to affect photosynthetic efficiency or cause sunburn on the fruit.
2. Water management
After autumn, the temperature gradually turns cooler, and it is also a season when rainfall is relatively concentrated, so drainage in the orchard is relatively important. Fruit growers should check the water accumulation in the orchard at any time, drain water and clear ditches, and reduce damage to the root system caused by water accumulation, high temperature, and excessive moisture. Especially in early autumn, if the temperature reaches above 35 degrees, the dry hot wind produced by the dry climate often causes kiwifruit leaf edges to dry up and curl upward, and the fruit will also be sunburned. Therefore, during high temperature and drought, water should be applied in time to preserve moisture and lower the temperature.
3. Weeding
After entering the rainy season, rainfall is concentrated, and sufficient moisture will lead to the breeding of a large number of weeds. Therefore, fruit growers should promptly control the weeds in the orchard, weed at the appropriate time, increase ventilation and light transmission, reduce humidity, and reduce the probability of pests and diseases. The cut weeds can be used to cover the tree盘 [tree盘]. After rotting, they increase the organic matter in the orchard, improve the soil aggregate structure, and increase the soil's water and fertilizer retention capacity.
4. Pest and disease control
After the Beginning of Autumn is also a period of high incidence of kiwifruit pests and diseases. The main pests and diseases include soft rot, gray mold, stink bugs, leafhoppers, etc. If not controlled in time, it will not only cause leaf drop and fruit drop, but also cause diseases in the fruit during harvest and storage. Therefore, the right medicine should be applied according to the occurrence of pests and diseases. According to the condition, choose triazole fungicides, 80% thiophanate-methyl wettable powder 1000-fold solution, procymidone, and other agents for control. For insect pests, cyhalothrin 1500-fold solution or beta-cypermethrin 1500-fold solution can be selected for alternating control to avoid resistance.
