Detailed Explanation of Key Points for Spring Management Techniques of Plum Trees
The plum is a fruit of the Rosaceae family, also known as Jiaqingzi, mountain plum, and so on. Plums can promote the digestion of substances such as gastric acid and digestive enzymes. They can increase appetite and promote digestion, and plums are now planted quite widely across our country. As time gradually passes, spring is also approaching, so how should we manage plum trees when growing plums in spring? Below, let the editor introduce the key points for spring management of plum trees!
1. Spring Clearing of the Orchard
Spring is the season when all things revive. Not only will plum trees gradually recover their growth, but the overwintering disease and insect pathogens will also gradually awaken. Therefore, before the new buds of the plum trees begin to sprout, we must promptly destroy the overwintering sites of disease and insect pathogens such as dead branches, fallen branches, fallen flowers, and weeds in the plum orchard. Collect them and take them out of the orchard for burning or deep burial. Then spray the orchard with insecticides and fungicides to disinfect it promptly, eliminate the overwintering disease and insect pathogens, reduce pathogens, and lower the incidence of pests and diseases.
2. Fertilizer and Water Management
In early spring, sufficient water must be ensured. Adequate water is the key to ensuring the normal growth of plum trees and increasing yield throughout the year. It has a very large impact on the sprouting of new buds and flower bud differentiation of plum trees. If drought occurs during the budding period, water promptly to end the root dormancy period, increase the soil water content and the soil's heat preservation capacity. Promote root respiration, enhance disease resistance, appropriately spray rooting agents to promote root growth and increase the rate of flowering and fruiting.
3. Whitewashing the Trunk
Whitewashing the trunk is generally done in winter. Whitewashing the trunk of plum trees can effectively prevent disease and insect pathogens from overwintering in the bark. If whitewashing in spring, it is generally done around mid-February, and the height should be controlled according to the tree's growth vigor. Usually, it is enough to whitewash up to the branching part of the trunk. Pay attention to larger cracks in the bark and branches to prevent missing spots. When whitewashing, you can mainly choose liquid protective film for fruit trees, which has strong water resistance, and appropriately apply field disinfectant to prevent pest and disease damage.
4. Preventing Late Spring Cold
Late spring cold is one of the most common problems in spring, because spring temperatures gradually rise but fluctuate greatly, making late spring cold very likely. Flower buds are very easily damaged by late spring cold, affecting the yield of plum trees. Therefore, in spring we must take good management measures to prevent the occurrence of late spring cold. Generally, we can appropriately spray growth regulators and foliar fertilizers. Then combine watering and smoking to do a good job of heat preservation, strengthen preventive measures against late spring cold, and prevent it from affecting the growth of plum trees.
5. Preventing Pests and Diseases
As just mentioned, spring is the peak period of activity for disease and insect pathogens, so in spring special attention must be paid to pest and disease control. In addition to the basic work above, we should regularly spray pesticides for prevention and control and strengthen management. For insecticides and fungicides, pesticides such as Bihaike and Zhengsheng can be used. The main targets for control include aphids, plum pouch fruit disease, and so on. Prevention work should be carried out purposefully and directionally to avoid affecting planting benefits.
The above is a brief introduction to the key points for spring management of plum trees. The spring management work of plum trees is very important. It is directly related to the economic benefits of planting that year, so everyone must pay close attention to it. That is all for today's introduction. This article is for reference only.
