Problems solved by technology

Fertilization is one of the most effective ways to improve the yield and variety quality of walnuts. However, in the production management of walnut planting, there is an unreasonable phenomenon of fertilization, that is, the long-term application of chemical fertilizers leads to the lack of soil organic matter and the imbalance of tree nutrition. At the same time, the existing walnut The use of fertilizers has the problem of relatively single nutrient composition and incomplete nutrition, which leads to the walnuts being not full and having a certain empty shell ratio, resulting in low yield and poor quality of walnuts. In order to solve this problem, the application of organic fertilizers suitable for walnuts should be increased
