How to Increase Walnut Yields? These Methods Are Very Practical

The 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 oilseed crop. The nutritional value of walnuts is extremely high. As the saying goes, "eating walnuts nourishes the brain" - this actually has a certain medical basis, because walnuts are rich in protein and many trace elements essential to the human body. Good market prospects have attracted many people to grow them, but how should they 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 excellent saplings. This is the foundation for ensuring high yield and high quality in walnut trees. We can choose varieties suitable for planting according to the weather, soil and environment of the planting area. Because most saplings 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. The saplings should maintain robust growth, with a height of about 50-70 cm, 15-20 lateral roots, and ideally be disease-free and pest-free saplings. This can achieve twice the result with half the effort and lay a solid foundation for planting.

2. Nutrition

The nutrition referred to here means the application of fertilizer. All plants cannot lack nutrition during cultivation. To make walnuts grow and develop rapidly, sufficient nutrition must be ensured. Fertilizing walnut trees is mainly done in the early stage of planting, to promote the growth and development of the saplings and strengthen the resistance of the tree body. About three months after planting, pre-flowering fertilizer can be applied as a top dressing to promote nutrient absorption by the saplings and increase their growth rate. Pre-flowering fertilizer is mainly nitrogen fertilizer, but it should not be excessive, to prevent excessive vegetative growth of the saplings. After that, at least two more top dressings should be applied: one is fruit-setting fertilizer, and one is fruit-swelling fertilizer, to increase the fruit-setting rate and ensure yield.

3. Pruning

Shaping and pruning is work that must be carried out for all large trees. If the tree shape of walnut trees is not managed in time, it will reduce the growth rate of the 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 aeration and light penetration, triggering various diseases and pests and leading 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. Cut off all water sprouts, excessively dense branches and diseased branches from the tree body to strengthen the orchard's aeration and light penetration. Give the fruit trees a better growing environment. After pruning, treat the wounds promptly 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, according to the soil conditions and the growth progress of the walnut trees, carry out loosening and weeding work. Loosening the soil is to strengthen the permeability of 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 becoming too vigorous and competing with the fruit trees for nutrients, affecting the orchard's permeability and causing nutritional deficiencies in the fruit trees. Therefore, proper soil loosening and weeding are very good for the growth of walnut trees.

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