Daily maintenance and management points of the latest plum trees

We all know that plums are fruits from plum trees, and it takes a lot of time to manage in the process of planting. The main thing is to do a good job in daily maintenance, such as the branch growth rate of plum trees is very fast. So pruning is a more important step for it, in addition to strengthen its fertilizer and water management and other conservation, then the following will give you a detailed explanation!

Pruning plum trees

The key point of pruning plum trees lies in their short fruit branches, because their blossoms and fruits are mainly short fruit branches, so we should pay attention to the pruning of short fruit branches. In the first year, we should focus on tree shape shaping and branch density control to ensure the perfect shape of the whole plant. When it comes to the fruiting period, we should pay attention to the pruning of lateral branches and trunk branches, so that they can grow more short fruit branches, shorten the fruiting cycle, and prune the over-dense branches. Coring the branches in time to promote the differentiation of flower buds.

II. Fertilizer and water management

1. Topdressing the tree after fruit harvest and pruning, especially the re-fruiting after fruit harvest and the re-growth of branches will consume a lot of nutrients, so we have to dig ditches in the field, apply mature fertilizer and element compound fertilizer in the ditch, and then water thoroughly.

2. Fertilization is mainly applied on the leaves, and then spread through the leaves. Of course, the environmental impact is also a big factor. If the temperature is high and the light intensity is too weak, the leaves will become very brittle. Therefore, fertilization on the leaves can make the leaves thicker, the leaves larger, the ability to accept fertilizer stronger, the intensity of photosynthesis will be greater, and it can produce more substances beneficial to the plant. In the early stage of the plum tree, the multi-element compound fertilizer with amino acid as the main element is mainly applied to supplement the nutritional needs in many aspects. The effect can be seen by spraying every other week and spraying for a month. When entering the height of summer, it can be replaced with potassium dihydrogen phosphate-based fertilizer to apply.

3. The base fertilizer will be applied at the end of summer. In preparation for autumn, the base fertilizer is mainly high-quality organic fertilizer, one-time fertilization is sufficient, and then watering is diluted. There is nothing to pay attention to above watering. The cold resistance of plum trees is also relatively strong, basically in accordance with normal watering, but to prevent waterlogging, sometimes heavy rain or accidental watering has caused stagnant water. All these need to be paid attention to.

4. Then there are the pest control methods that plum trees will have. Plum trees will be sprayed with insecticides and fungicides after pruning and fruit harvesting. Insecticides are mainly aimed at mites, and mites can be used to kill insects. In addition, carbendazim can be used for sterilization. As we all know, there is also bacterial perforation and a disease that likes to prevail in June. And some diseases and insect pests such as red spider, caterpillar moth and brown rot should be paid attention to. Once found, carbendazim, acaricide and methyl topiramate can be used alternately, which can achieve a very high control effect. Early detection and early control should be achieved.

5. To promote the differentiation of flower buds, plants can be sprayed with paclobutrazol wettable powder in June, and then sprayed according to the actual growth situation to control the nutrition needed for growth. In late November, plum trees can be sprayed with high-quality urea to promote leaf defoliation, which can be effective after spraying for three or four days, which can shorten the greenhouse time.

The above are the main points of daily maintenance and management of plum trees. have you learned it? The daily maintenance of plum trees includes pruning and fertilizer and water, there is no other, do these basically can be smooth results, but also pay more attention to diseases and insect pests, the occurrence of diseases and insect pests has a great impact on its growth, if you want to know more related knowledge, please continue to pay attention to the pro-agriculture network!
