Plum tastes sweet and sour, tastes good and is liked by everyone. There are also many people who plant plum trees. However, there is a problem in the planting process. There is nothing wrong with the management in the early stage, and the management after harvesting has not kept up, which has greatly reduced the output in the coming year. It is obvious that the management after harvesting is also very important. Guarantee. Then let's take a look at the management points and precautions after the harvest of plums.

1, reasonable pruning
After the harvest of the plum, it is necessary to pruning in time. This pruning mainly cut off diseased branches, dense branches, long branches, etc., avoiding excessive consumption of nutrients, improving the permeability of the trees, increasing the nutrient accumulation of plum trees, and laying the foundation for the next year's flowering results. When trimming, keep a back branch every 30~40 cm, and remove the extra one as soon as possible.
2, deep turning loose soil
In summer, the temperature is high and the humidity grows a lot of weeds under the plum trees, and the tree grows to compete for nutrition. Therefore, after harvesting, it is necessary to deepen the loose soil. The depth of the loose soil is generally about 25 cm, which improves the permeability of the soil and achieves the purpose of improving the soil. After deep turning, the manure should be applied to each plum tree, which can not only weed, but also enhance the soil fertility, improve the cold resistance and drought resistance of the tree, reduce the wintering base of the bacteria, and ensure the normal growth after the plum tree.

3, scientific topdressing
After the harvest of plums, the nutrition of the tree will be reduced. In order to ensure the normal flowering results in the next year, it should be properly topdressed. Generally, each plum tree is applied with urea 0.3~0.5 kg and potassium dihydrogen phosphate 0.2~0.3 kg. Combined with pest control, some foliar fertilizers can also be added. After topdressing, water should be poured in time to promote the growth of the tree. Deeply turning the land into the base fertilizer is the key to ensuring a bumper harvest 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 growth capacity of the tree will be weakened, which is susceptible to infection by pests and diseases. Therefore, after harvesting, the orchard should be properly disinfected to bring the sick bodies and weeds in the hospital out of the orchard. The common pests and diseases of plum trees include perforation, leafhopper, red spider, etc. Before harvesting, if the treatment is not complete, it can be the best period of prevention after harvesting. It can be effectively prevented by spraying 750 times with speed (bactericide) and spraying 2~3 times.
