The people who planted kiwifruit have the experience that the kiwifruit grows vigorously in the early stage. After 7 to 8 years of fruiting, the continuous result is very strong, but after 10 years, the tree has premature aging in varying degrees. So how to overcome this phenomenon?
Control the yield of kiwifruit during the fruiting period, strictly control the yield, ensure that the per mu yield is 2500~3000 kg, and use the high-efficiency one-word shaping technology in the winter to reasonably leave the branches and stay buds. The remaining shoots must be strong and full. After the result, the results should be updated in time to keep new branches every year and achieve good results every year.
The thinning and thinning fruit pays attention to the flowering fruit, the ratio of leaf to fruit is 6:1, the tree is more than the flower, and the weak tree is less. The remaining fruit per acre can be between 30,000 and 35,000. But you can't die hard, you should be flexible according to the tree of your own orchard.
Strengthen the management of fertilizer and water to apply 5000~6000 kg of decomposed organic fertilizer per mu. The base fertilizer is applied immediately after the kiwifruit is harvested, and the water is poured to increase the soil organic matter content. Topdressing mainly captures the pre-emergence period, the fruit expansion period, and several top dressings before and after fruit picking. The sprouting fertilizer is mainly composed of high nitrogen, low phosphorus and medium potassium. During the expansion period, it is mainly composed of medium nitrogen, low phosphorus and high potassium. Before and after the kiwifruit harvest, the base fertilizer is applied, and the balanced fertilizer is mainly used, such as 45% compound fertilizer or 51% compound fertilizer.
Strengthen the prevention and control of pests and diseases Before the germination, the whole garden spray is carried out with 3~5 Bomei stone sulphur mixture. Spring is the high incidence of ulcer disease. It is inspected and observed in the orchard. Once it is discovered, it is immediately eradicated. Diseases in the growing season include early defoliation, spot disease, black spot, kiwi flower rot, insect mites, spotted wax mites, stink bugs, chafers, red spiders, and the like. Prevention and control of pests and diseases should be based on prevention and prevention.
