How to prevent premature aging of the kiwi tree

Kiwifruit grows vigorously in the early stage. After 7 to 8 years in the full fruit period, the ability to continue fruiting is very strong. As a result, after 10 years, the tree will appear premature aging to varying degrees. How to overcome this phenomenon?

Controlling Yield During the fruiting period, kiwifruit should be strictly controlled to ensure that the yield per mu is 2500-3000 kg. In winter, the high-light-efficiency orthopedic technology should be used rationally, and the branches and buds must be kept strong and full in winter. After the results, the fruiting branches should be updated in time to keep new branches every year and produce good fruits every year.

Flower and fruit thinning emphasizes on flower and fruit thinning, with a leaf-to-fruit ratio of 6:1. The prosperous trees retain more flowers and fruits, and the weak ones retain less. There are 30,000 to 35,000 fruits per mu. But you can't do it hard, you should be flexible according to the tree vigor of your orchard.

Strengthen fertilizer and water management, apply 5000-6000 kg of decomposed organic fertilizer per mu. The basal fertilizer is applied immediately after the kiwi fruit is harvested, and sufficient water is added to increase the soil organic matter content. The germination fertilizer is mainly high nitrogen, low phosphorus and medium potassium. The expansion period is dominated by medium nitrogen, low phosphorus and high potassium. Before and after the kiwi fruit is harvested, apply base fertilizer, mainly balanced fertilizer, such as 45% compound fertilizer or 51% compound fertilizer.

Strengthen the prevention and control of pests and diseases. Before germination, spray the whole garden with a lime-sulfur mixture of 3 to 5 Baume degrees. Spring is the period of high incidence of ulcers. Frequent inspections and observations in the orchard will eliminate them as soon as they are found. Diseases include early leaf fall disease, spot disease, black spot disease, kiwi fruit flower rot, etc. Insect pests include leafhoppers, waxhoppers, stinkworms, scarabs, and red spiders. The prevention and control of plant diseases and insect pests should be based on prevention and combined with prevention and control.
