The latest fertilization methods for walnut trees

Walnut, also known as walnut, is one of the four famous nuts in the world, which is rich in nutrients and is of great benefit to the human body. According to expert research, the best number of walnuts to eat every day is six. It can be said that China is a big walnut growing country with a wide range of planting, including North China, Northwest, Southwest, Central China, South China and East China, especially Bozhou in Anhui Province is the largest walnut forest farm in Asia. So fertilizing is very important when planting walnuts. Do you know how to fertilize walnut trees? Next, let's study with the editor.

1. Base fertilizer

The amount and species of fertilizer required for walnut trees are different in different growth periods, and the application of base fertilizer is the basic condition for the growth of walnut trees. For Yuanbao, the base fertilizer is mainly organic fertilizer or rotten farm manure. In addition to the so-called base fertilizer applied at the beginning of planting, base fertilizer needs to be applied in autumn or spring every year during the late growth of walnut trees. This can promote the differentiation of flower buds and the growth of roots, thus increasing the yield of walnut trees. When applying fertilizer, we usually apply fertilizer combined with deep ploughing, and we need to water it after fertilization, which is conducive to the absorption of nutrients.

Second, topdressing

Topdressing walnut trees, that is, on the basis of base fertilizer, according to the different stages of walnut tree growth, reasonable provision of nutrients, which is conducive to improve the yield and quality of walnut, and ensure the growth of walnut trees. Generally speaking, at least three times of topdressing are needed in the growth process of walnut. Let's learn more about it.

1. Growth fertilizer

The growth fertilizer of walnut is generally applied reasonably according to the growth of walnut according to a growth situation of walnut, which is used to promote the growth of new branches of walnut and promote flowering so as to shorten the growth period. In this topdressing, we are mainly based on available nitrogen fertilizer, and combined with a small amount of phosphate fertilizer. At the same time, the amount of topdressing can be said to account for about half of the total topdressing, because if the amount of topdressing is not enough, it is likely to affect the growth and development of walnut trees, thus affecting flowering and fruiting.

2. Flower and fruit fertilizer

Flower and fruit fertilizer is generally carried out before and after flowering, mainly in order to promote flower blooming and achieve the effect of promoting flowers and protecting fruits. We still use nitrogen fertilizer as the main fertilizer this time, but we need to cooperate with the use of phosphorus and potassium fertilizer. Topdressing during this period can reduce the phenomenon of falling flowers and fruits caused by lack of nutrition, at the same time, it is conducive to the growth of branches and promote the delivery of nutrients in place.

3. Strong fruit fertilizer

Strong fruit fertilizer is usually a topdressing in the fruiting period, which is about the end of June, and it is also the last topdressing in walnut planting from flowering to fruiting. This time, topdressing is mainly based on phosphorus and potassium fertilizer, and then combined with the application of a small amount of nitrogen fertilizer to maintain the balance of nutrition. The main purpose of this topdressing is to improve the quality of walnut and to lay the foundation for high yield in the coming year.

Generally speaking, the fertilization process of walnut trees is like this. At the same time, when we apply fertilizer, we can use the whole garden sprinkling method, radial fertilizer method, ring fertilizer method, hole fertilizer method, strip fertilizer method, disc fertilizer method and other methods, which are all very common fertilization methods, and you can also learn from them.
