Problems solved by technology

Chinese cabbage has a large planting area in my country, and the market demand is large. In the process of planting Chinese cabbage, there are too many topdressing fertilizers, unreasonable fertilizer components, and low fertilizer efficiency, which can easily lead to excessive nitrate content in Chinese cabbage, affecting the quality of Chinese cabbage and endangering the human body. Healthy, and the long-term application of fertilizers can easily cause soil compaction, and at the same time lead to deterioration of the soil environment, seriously affecting the sustainable development of my country's agriculture
