Fertilization methods of Walnut trees

Walnut, also known as walnut, is one of the world's four famous nuts, rich in nutrients, and has great benefits for the human body. According to expert research, the optimal number of walnuts to eat daily is six. China can be said to be a big walnut planting country with a wide planting range, including North China, Northwest China, Southwest China, South China and East China, especially Bozhou, Anhui Province, which is the largest walnut forest farm in Asia. So fertilization is critical when planting walnuts. Do you know how to fertilize walnut trees? Let's learn together with Xiaobian below.

1. Base fertilizer

Walnut tree its different growth periods, the amount of fertilizer required, fertilizer species are different, and the application of base fertilizer is the basic conditions for walnut tree growth. For Yuanbao, the base fertilizer is mainly organic fertilizer or decomposed farm manure. In addition to the base fertilizer applied at the beginning of planting, the base fertilizer should be applied in the autumn or spring of each year during the later growth of walnut trees. This can promote flower bud differentiation and root growth, thereby improving the yield of walnut trees. When fertilizing, we usually combine deep ploughing for fertilization, and watering is needed after fertilization, which is conducive to nutrient absorption.

II. Topdressing

To walnut tree topdressing, that is, on the basis of base fertilizer, according to the different stages of walnut tree growth, reasonable provision of nutrients, so as to improve the yield and quality of walnut, to ensure the growth of walnut trees. Generally, at least three topdressing treatments are needed in the growth process of walnuts. Let's learn more about it in detail below.

1. Growth fertilizer

Walnut growth fertilizer is generally based on a walnut growth situation after the base fertilizer, reasonable topdressing, used to promote the growth of new walnut branches, and promote flowering, to shorten the growth period of a role. In this topdressing, we mainly use quick-acting nitrogen fertilizer, and with a small amount of phosphorus fertilizer for topdressing. At the same time, the topdressing amount can be said to account for about half of the total topdressing amount, because if the topdressing amount 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

Flowering and fruit fertilizer is generally carried out before and after flowering, mainly to promote flowering and achieve the effect of promoting flowers and fruits. This time, we still use nitrogen fertilizer as the main fertilizer, but we need to use phosphorus and potassium fertilizer together. If topdressing is carried out during this period of time, it can reduce the phenomenon of flower and fruit drop caused by insufficient nutrition, and at the same time it is beneficial to the growth of branches and promotes the transportation of nutrients in place.

3, strong fruit fertilizer

Fruit fertilizer is generally a topdressing in the fruiting period, which is about the end of June, and is also the last topdressing in the process of walnut planting from flowering to fruiting. This topdressing is mainly based on phosphorus and potassium fertilizer, and then a small amount of nitrogen fertilizer is applied to maintain a balanced nutrition. This topdressing is mainly to improve the quality of walnuts, but also for the next year's high yield to lay the foundation.

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 sowing method, radial fertilization method, ring fertilization method, hole fertilization method, strip fertilization method, disc fertilization method and other methods, these are very common fertilization methods, we can also learn from it.
