What's wrong with walnut trees that don't bear fruit? Attached cultivation techniques

Walnut trees, also known as walnut trees, are planted in many places in China, most of them are artificially improved varieties, so that the yield is higher and the skin is thinner. The fruit of walnut tree is rich in nutrients and has a strong fragrance, which is deeply loved by consumers. In addition, walnut trees can also be used as shelterbelts for roads and have certain economic value. Walnut trees have relatively strict requirements for planting land, and growers often react to the phenomenon that walnut trees do not bear fruit. How is that going on? What are the key points of cultivation techniques?

First, what's wrong with walnut trees that don't bear fruit?

1. Planting time is not enough.

Walnut trees bear fruit later than other fruit trees, and it usually takes three years to blossom and bear fruit. If you plant later, the result will be a little later, and it may take five years to bear fruit, or even longer.

2. The management method is incorrect

Walnut trees were not properly managed after planting, which affected the growth of walnut trees to a certain extent. For example, insufficient water, insufficient fertilizer, improper pruning, poor pollination and other phenomena of walnut trees will lead to the occurrence of sterile phenomena.

3. Caused by diseases and insect pests

If walnut trees are attacked by diseases and insect pests, it is likely that they will not blossom or bear fruit. At this time, we should choose the right way to carry out scientific prevention and treatment. It is common to encounter maggots during flowering, and many female flowers are nibbled away, which naturally does not bear fruit.

2. Cultivation techniques of walnut trees

1. The choice of planting site

If you plant walnuts, it is very important to choose planting land, generally choose sunny, leeward, convenient irrigation, convenient gentle slope, flat land, front and back of the house, and so on.

2. Soil conditions

Walnut is suitable for growing in sandy soil or sandy loam with good air permeability, good water retention and good looseness. The soil layer should be deeper, and more than one meter is recommended.

3. Select seedlings

Only high-quality walnut seedlings can grow walnuts with high yield and good quality. Therefore, the general selection of walnut seedlings is two or three years of strong seedlings better than the price, the height should be greater than 30cm, the ground diameter can not be less than 1cm. In addition, walnut seedlings have more roots and are free from diseases and insect pests, so that the survival rate of planting is higher.

4. Watering

Walnut trees can not grow without water, especially in the growth period of young trees, so the requirements for drainage and irrigation are relatively high. Specific according to the soil wettability and growth period to determine the amount of water, can not be long-term stagnant water can not be long-term drought, both phenomena are not conducive to the growth of walnut trees.

5. Fertilization

Fertilization is an important means to ensure the normal growth of walnut trees and to achieve high yield and stable quality. Walnut trees in different growth stages have different demand for fertilizer.
