What are the latest methods to increase walnut yields?

Walnut is known as one of the world's four major nuts. It can not only be processed into nuts for consumption, but is also a very good oil crop. The nutritional value of walnuts is very high. As the saying goes, “eating walnuts nourishes the brain”, and this actually has a certain medical basis. Because it contains rich protein and many trace elements essential to the human body. Its good market prospects have attracted many people to grow it, but how should it be grown to achieve high yields? Today, the editor brings you methods to increase walnut yields.

1. Seedling selection

First of all, before planting, you must select superior seedlings. This is the foundation for ensuring high yield and high quality of walnut trees. We can choose varieties suitable for planting according to the weather, soil and environment of the planting area. Because most seedlings are grafted nursery stock, when selecting seedlings we should also pay attention to checking whether the wounds have healed, or whether the degree of healing is complete, etc. The seedlings should maintain robust growth, with a height of about 50-70 cm, 15-20 lateral roots, and disease-free, pest-free seedlings are best. This can achieve twice the result with half the effort and lay a good foundation for planting.

2. Nutrition

The nutrition referred to here is the application of fertilizer. All plants cannot lack nutrition during cultivation. To make walnuts grow and develop quickly, it is even more necessary to ensure sufficient nutrition. Fertilizing walnut trees is mainly done in the early stage of walnut tree planting, to promote the growth and development of seedlings and strengthen the resistance of the tree body. About three months after planting, pre-flowering fertilizer can be applied to promote nutrient absorption by the seedlings and increase the growth rate of the seedlings. Pre-flowering fertilizer is mainly nitrogen fertilizer, but it should not be excessive, to prevent excessive vegetative growth of the seedlings. After that, it should be applied at least two more times: once as fruit-stabilizing fertilizer and once as fruit-strengthening fertilizer, to improve the fruit-setting rate and ensure yield.

3. Pruning

Shaping and pruning is work that all large trees must undergo. If the tree shape of walnut trees is not managed in time, it will reduce the growth rate of walnut trees and prevent the canopy from forming in time. Moreover, when walnut trees reach the final stage, the bearing capacity of the tree body will gradually decline. During fruiting, this causes poor permeability, triggers various diseases and pests, and leads to poor walnut quality. Therefore, in order to promote early maturity and high yield of the fruit trees, we should carry out appropriate pruning work on the fruit trees. Remove all water sprouts, overly dense branches and diseased branches from the tree body to strengthen orchard permeability. Let the fruit trees have a better growing environment. After pruning, treat the wounds in time to prevent pathogen invasion and disease.

4. Soil

In addition to the above three points, the soil should also be properly managed. During the planting process, carry out loosening and weeding according to the soil conditions and the growth progress of the walnut trees. Loosening the soil is to strengthen the permeability in the soil, which is beneficial to the respiration of the tree roots and enhances the nutrient absorption capacity of the tree roots, but attention should also be paid to the soil's water and fertilizer retention. Weeding is to prevent weeds from growing too vigorously and competing with the fruit trees for nutrients, affecting orchard permeability and causing nutritional deficiency in the fruit trees. Therefore, proper soil loosening and weeding are very good for the growth of walnut trees.

The above four points are methods to increase walnut yields. Growing walnuts still requires you to master certain cultivation techniques. Before planting, make all planting preparations, ensure the environment required for planting, and improve the survival rate of planting, so as to ensure the yield and quality of walnuts.
