Management Points and Precautions for Plum Collection

Plums taste sour, sweet, and tender, and have a good taste and are popular with everyone. At present, many people plant plum trees. However, there is a problem in the planting process, that there is no error in the previous management, and the management after harvest has not kept up, which has led to a significant reduction in the output in the next year. It can be seen that the management after harvest is also very important. Protection. Then let's learn the management points and precautions of plums after harvesting.

1. Reasonable trim

After the plums are harvested, they should be trimmed in time. This pruning mainly cuts off the diseased branches, dense branches, long branches, etc., to avoid consuming excessive nutrients, improve the permeability of the tree body, increase the nutrient accumulation of the plum tree, and lay the foundation for the next year's flowering and fruiting. When pruning, keep a branch on the back every 30-40 cm, and remove the extra as soon as possible.

2. Deep turning loose soil

Under the high temperature and humidity in summer, a lot of weeds grow under the plum tree and compete with the tree for nutrition. Therefore, after harvesting, the loose soil should be deeply turned. The depth of the loose soil is generally about 25 cm to improve the permeability of the soil and achieve the purpose of improving the soil. After deep turning, sufficient manure should be applied to each plum tree, not only to weed, but also to enhance the fertility of the soil, improve the cold and drought resistance of the tree body, reduce the wintering base of pathogens, and ensure normal growth of the plum tree in the future.

Essentials of post-harvest plum management

3.Scientific topdressing

After the plums are harvested, the nutrition of the tree will be reduced. In order to ensure normal flowering and fruiting in the next year, fertilization should be reasonable. Generally, 0.3 to 0.5 kg of urea and 0.2 to 0.3 kg of potassium dihydrogen phosphate are applied to each plum tree. Combined with pest control, some foliar fertilizers can also be added. After topdressing, watering should be timely to promote the restoration of tree growth. Deeply turning over the land and applying basal fertilizers is the key to ensuring a high yield in the second year.

4. Pest control

After the plums are harvested, a large amount of nutrients in the tree will be lost, and the tree's growth ability will be weakened, and it will be susceptible to infection by pests and diseases. Therefore, after harvesting, the orchard should be properly disinfected, and the sick bodies and weeds in the hospital should be brought out of the orchard. Common pests and diseases of the plum tree include perforation, leafhoppers, red spiders, etc. Before harvesting, if the disease is not completely treated, it is the best time to control after harvesting. It can be effectively controlled by spraying 750 times of Sudu (bactericide) twice or three times.
