Management of chestnut after chestnut picking "four steps"
The beginning of September-October is the beginning of flower bud differentiation of chestnut tree production in the following year. The management after harvesting directly affects the output of the following year. Well, it is good to eat, drink, wear, and care. Stepping is particularly important. First, rational fertilization, give enough "eat". Generally, the development and maturation of chestnut needs to consume 4.5-5 kg ​​of pure nitrogen and potassium and 1.5-2 kg of phosphorus per 100 kg of chestnut. After the fruit is harvested, fertilizer should be added in time, and the fertilizer is mainly organic fertilizer. The trees are usually 8-10 years old. Each plant has 50-60 kg of manure, 0.5 kg of urea and 1 kg of phosphate fertilizer. The tree grown more than 10 years old will increase the amount of fertilizer according to the amount of the results. Second, irrigation drought, give enough "drink." After the fruit is harvested, the water loss of the tree is very large. In addition, during the agricultural season, the autumn and winter droughts are more serious and it is easy to make the chestnut trees suffer from drought. Therefore, the chestnut trees that are conditional after fruit harvesting must be filled with water once in a timely manner. Irrigation also needs timely. Third, earthworms, give enough "to wear". In mid-late and late November, each tree is sized with 2-4 pieces of decomposed garbage and pond mud, and it is tiled under the canopy centered on the trunk and covered with a layer of fine soil. When the temperature in late spring rises, it will be dug again to facilitate long-term ventilation and reduce the growth of weeds. Fourth, pest control and treatment, "Health Care." After the fruit is harvested, the garden is cleaned in time, and the dead branches, disease and insect branches are cut off, the branches and leaves of the diseases and insects that have fallen off the ground are removed, and burned or buried deeply. Autumn chestnut pests and diseases should be timely application of pesticides, pesticides can be used times the amount of Bordeaux mixture, 40% omethoate emulsion 1500-2000 times the liquid, 2.8% 8000 emulsion killed EC.
