Five points of management of kiwifruit after autumn
Shearing After entering August, after the beginning of autumn, it is necessary to strengthen the ventilation and light transmission of the frame to enhance the photosynthetic nutrient manufacturing capacity and improve the fruit quality. The purpose of ventilation and light transmission of the fruit can be achieved by moderately cutting the result. The method is: for the result branch in the dense place, the number of fruits remaining in the front of the top fruit is equal to the number of the branches, or the number of fruits is 1.5 times. Pay attention to the strong, can be selected as the result of the next year, the cutting of the mother branch is long, or not cut. Insect control In July and August, sucking mouthparts pests, such as spider mites and spider mites, are easy to spread. Pay attention to spraying insecticides such as chlorpyrifos, avermectin, carbaryl salt and imidacloprid, as well as fungicides such as mancozeb and 45% dexamethasone. Anti-ulcer disease From the end of August, we must pay attention to the prevention of ulcer disease. Beginning in late August, the whole tree is sprayed with 20% thiabendazole 600 times solution, 50% leaf cumin 600 times solution, and neutrophin 600 times solution. It is sprayed once every 10 to 15 days to prevent ulcer disease. use. Add 3000~5000 times liquid penetrant to improve the efficacy of the agent. Combined with spraying, adding 0.3% to 0.5% potassium dihydrogen phosphate is beneficial to enhance disease resistance. Root repair For the field or plant with serious dry leaves and deciduous leaves in the early stage, the reasons should be analyzed and different measures should be taken: the root system is too deep (root root rot has not appeared in the root system), and the layer of soil in the root layer is uncovered. Use 1500 times liquid to lead you through the roots. After filling, do not cover the soil, cover the straw, after about 20 days, restore the tree slowly, and then re-irrigate the root; for root rot, use the mildew (according to instructions), or 300~400 times liquid 45% Dyson Ammonium, add rooting powder for rooting, and after half a month, use it to lead the way. Fertilizer management After the beginning of autumn, in order to avoid the stimulation of the growth of new shoots, the amount of phosphorus and potassium fertilizer should be increased to stop the excessive application of nitrogen fertilizer. For trees that are too busy, you can spray PBO, etc., to slow down the growth and increase nutrient storage. It is better to keep the water without water shortage (the leaf surface does not wilted at 14 noon). The early stage of the drought caused the leaves, issued new leaves, can be sprayed with 0.3% urea or 700 times liquid amino acid, algae, biotin, fulvic acid and so on. At the same time, use the pathogen to root the plants or plants that are used for dry leaves. Disclaimer: Some articles on this website are transferred from the Internet.
