The latest key points of plum management in spring

Plum is a kind of fruit of Rosaceae, also known as Jiaqingzi, mountain plum, etc., plum can promote the digestion of stomach acid and digestive enzymes. Can increase appetite, promote digestion and so on, now the plum planting area in our country is also more extensive. Now, with the passage of time, we will gradually enter spring, so how do we manage plum trees when we plant plums in spring? Next, the editor will introduce the key points of plum management in spring.

1. Clear the garden in spring

Spring is the season of recovery of all things, not only the plum tree will gradually return to growth, but also its overwintering diseases and insect pests will gradually awaken. Therefore, we should destroy the overwintering places of diseases and insect pests such as dead branches, fallen flowers and weeds in the plum orchard before the new buds of plum trees sprout. Concentrate on taking out the orchard for burning and deep burial treatment. Then spray insecticides and fungicides on the orchard in time to eliminate overwintering diseases and insect pests, reduce pathogens and reduce the incidence of diseases and insect pests.

2. Fertilizer and water management

To ensure sufficient water in early spring, sufficient water is the key to ensure the normal growth and increase the yield of plum trees in this year. It has a great influence on the new bud germination and flower bud differentiation of plum trees. If drought occurs in the bud, it should be watered in time to end the dormant period of the roots and improve the soil water content and soil heat preservation capacity. To promote root respiration and enhance disease resistance, rooting agents can be properly sprayed to promote root growth and improve the rate of flowering and fruiting.

3. Tree trunk whitening

Trunk whitening is usually carried out in winter. Painting the trunk of white plum trees can effectively prevent diseases and insect pests from overwintering in the bark. If you paint white in spring, it is usually carried out around mid-February, and the height of the tree is controlled according to the growth of the tree, usually to the branches of the trunk. Should pay attention to the larger gaps in the bark and branches and other places to prevent leakage. When painting white, we can mainly choose the liquid protective film of fruit trees, strong water resistance, appropriate field disinfectant to prevent the harm of diseases and insect pests.

4. Prevent the cold in late spring

Late spring cold is one of the most common problems in spring, because the temperature gradually picks up in spring, but it fluctuates greatly, so it is very easy to appear late spring cold. Flower buds are easily frostbitten by cold in late spring, affecting the yield of plum trees. Therefore, we should do a good job in the spring management measures to prevent the occurrence of late spring cold, generally can properly spray health conditioning and foliar fertilizer and so on. Then combined with watering, smoking and other work to do a good job of heat preservation, strengthen the preventive measures of late spring cold, to prevent affecting the growth of plum trees.

5. Prevention of diseases and insect pests

As I just said, spring is the peak of the activity of diseases and insect pests, so we should pay attention to the prevention and control of diseases and insect pests in spring. In addition to doing a good job in the above basic work, we should regularly spray pesticides for prevention and control and strengthen management. Insecticides and fungicides can be used to kill gram, Zhengsheng and other agents. The main control targets are aphids, plum bag fruit disease and so on. Prevention work should be carried out purposefully and directionally to avoid affecting the planting efficiency.

The above is a brief introduction of the key points of plum tree management in spring, and the spring management of plum tree is very important. It is directly related to the economic benefits of planting in that year, so we must pay more attention to it.
