At present, kiwifruit is on the market, but after the fruit is harvested, strengthening the management of the orchard is an important task. Yao Chunchao, an expert on kiwifruit research at the Northwest A&F University, reminded fruit farmers that kiwifruit should not be sloppy after fertilization, sterilization, weeding and disinfection.
First of all, it is necessary to apply fertilizer after harvesting. Generally, a mixture of urea and potassium dihydrogen phosphate is sprayed once every 10 days, and spraying continuously for 2 to 3 times. At the same time, combined with the application of photosynthetic nutrient film fertilizer, restore the tree potential and increase the nutrition of the tree. If the results are small in the current year and the tree is weak, the base fertilizer and quick-acting nitrogen fertilizer can be added.
Second, we must prevent pests and diseases. The pests after picking mainly include the sucking mouthparts pests such as the big green leafhopper and the planthopper, which can be sprayed with the mother tree of the general guardian tree; the diseases mainly include ulcer disease, brown spot and black spot disease, and the fungus can be used. 3000 times of alcohol or 1500 times of oxystroxate combined with a new high-fat film spray fruit tree to improve the tree's own resistance.
In addition, we must grasp the autumn shears. It is necessary to take measures such as topping and wiping off the secondary shoots to control the growth. It is also possible to control the prosperousness by spraying the medicament and blocking the upward flow of the dredging conduit. After the construction is completed, the branches and leaves should be thoroughly cleaned to alleviate the pests of the leap year.
