Key points for the management of the latest walnut trees

Walnut is known as one of the four dried fruits in the world. It is rich in nutrients and contains many essential substances for the human body. For example, some trace elements such as calcium and phosphorus, as the saying goes, "walnut tonifying the brain" is not unreasonable, it is one of the most popular nuts in our country. Walnut planting is becoming more and more common, walnut is easier to manage and more adaptable. So how to manage it after planting? Let's take a look at it with the editor.

1. Soil

For the good growth and development of walnut trees, suitable soil is essential, and the degree of soil fertility will directly affect the growth rate and fruit rate of fruit trees. Properly cultivate the soil, increase the water content in the soil, enhance the soil permeability, improve the soil fertility, promote the growth of walnut trees, and improve the yield and quality.

2. Pruning

Reasonable pruning is the key factor to make walnut trees high yield. if pruning after defoliation or budding is not conducive to wound healing, the tree is very prone to diseases and insect pests. Try to put the pruning time after harvest, pruning the tree at this time can effectively adjust the structure of the tree, although it will have a certain impact on the accumulation of nutrients, but the problem is not big.

3. Fertilization

The growth of walnut has a great demand for nutrition. When ploughing and cultivating soil, base fertilizer is applied, and the base fertilizer is fully mixed with the soil to enhance the fertility of the soil. In the later stage, topdressing was appropriate according to the growth of trees, weather changes and the degree of nutrition in the soil. Fertilizer can not be poured directly into the pit, pay attention to mix well with the soil, may burn out the roots.

4. Watering

Watering work must be carried out, after planting, we need to irrigate the fixed root water, and after each fertilization and topdressing, we should supplement water to promote the absorption of fertilizer nutrients by tree roots. Walnut is a kind of water-loving crop, in order to ensure the water needed in the growth process of walnut, it is necessary to replenish water in time in continuous dry weather to prevent walnut from water shortage and cause adverse effects on walnut growth and development.

5. Diseases and insect pests

Walnut trees have strong disease resistance, and there are not as many diseases and insect pests as other crops, but sometimes diseases and insect pests are caused by improper management. Failure to deal with diseases and insect pests in time, resulting in stunted growth or death. Regularly spray pesticides for prevention, inspect the orchard, determine the disease according to the incidence, and then treat the disease, and do a good job of orchard disinfection and cleaning after harvest.

6. Overwintering

Walnut likes to be wet and waterlogging-resistant but not cold-resistant. After harvest, walnuts also need to do a good job of overwintering to prevent frost damage. The lower part of the tree is painted white and brushed dry before winter, which plays a role in heat preservation. In case of heavy snow, sweep the snow around the tree in time. Cover with plastic film to increase the surface temperature and prevent frost damage.

The above six points are a brief introduction to the management points of planting walnut. If any of the above points are not carefully controlled, they will have a great impact on the growth and development of walnut. For example, if the diseases and insect pests are not dealt with in time, the production will be greatly reduced, the quality will be reduced, and the weight will lead to the death of the whole tree. Therefore, when planting, we must meet all the requirements for walnut growth, so that we can successfully survive and produce high yields.
