A Detailed Explanation of the Latest Key Technical Points for Spring Management of Plum Trees
Plum is a fruit of the Rosaceae family, also known as Jiaqingzi, mountain plum, etc. Plums can promote the digestion of substances such as gastric acid and digestive enzymes. They can improve appetite and promote digestion, etc. At present, plum cultivation in China is also relatively widespread. Now as time slowly passes, spring is gradually approaching, so how should we manage plum trees when growing plums in spring? Below, let me introduce the key points of spring management for plums!
1. Spring Orchard Cleaning
Spring is the season when all things revive. Not only will plum trees gradually recover their growth, but the overwintering pests and disease pathogens will also gradually awaken. Therefore, before the new buds of plum trees sprout, we should promptly destroy the overwintering sites of pests and disease pathogens, such as dead branches, fallen branches and flowers, and weeds in the plum orchard. Gather them and take them out of the orchard for burning or deep burial. Then spray insecticides and fungicides on the orchard for timely disinfection, eliminate overwintering pests and disease 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 should be applied promptly to end the dormancy period of the roots, improve the soil's water content and soil heat preservation capacity. Promote root respiration, enhance disease resistance, and appropriately spray rooting agents to promote root growth and improve the flowering and fruiting rate.
3. Trunk Whitewashing
Trunk whitewashing is generally carried out in winter. Whitewashing the trunk of plum trees can effectively prevent pests and disease pathogens from overwintering in the bark. If whitewashing in spring, it is generally carried out around mid-February. Control the height of the tree according to its growth condition, and usually whitewash up to the branching part of the trunk. Pay attention to large cracks in the bark and branches, etc., to prevent missing spots. For whitewashing, fruit tree liquid protective film can mainly be selected, which has strong water resistance. Add appropriate 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 late spring cold. Generally, growth regulators and foliar fertilizers can be appropriately sprayed. Then, combined with watering and smoking, do a good job in heat preservation work, 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 pest and disease pathogen activity, so in spring special attention should be paid to pest and disease prevention and control. In addition to the basic work above, we should regularly spray chemicals for prevention and control and strengthen management. For insecticides and fungicides, chemicals such as Bihaike and Zhengsheng can be used. The main targets of control include aphids, plum pouch fruit disease, etc. Prevention work should be carried out purposefully and directionally to avoid affecting planting benefits.
The above is a brief introduction to the key points of spring management for plum trees. The spring management work of plum trees is very important. It is directly related to the economic benefits of cultivation that year, so everyone must pay close attention. That is all for today's introduction. This article is for reference only.
