Yes, it is easy for seedlings to die and rot, with low yield and poor quality. You need to use professional anti-recropping products: Wanmukang re-cropping agent is developed by the Chinese Academy of Agricultural Sciences, the China Soil Research Institute and the China National Soil Research Institute. The School of Bioengineering has developed a special anti-recropping and soil remediation agent based on China's current agricultural situation. National patent has been applied for. This product is mainly produced by using microbial metabolites, photosynthetic super carbon and melicin as the core technology, using highly active humic acid as the carrier, and using high-concentration double chelation technology. Wanmukang's re-cropping agent is based on microbial metabolites, photosynthetic super carbon and benzoin as the core technology, with highly active humic acid as the carrier, and complexes the most deficient boron and zinc elements in my country's soil, using high-concentration double Produced by chelation technology. We will start from the three major obstacles to repeated cropping: malnutrition of crops, large amounts of pathogens, and soil poisoning to comprehensively solve the problem of repeated cropping. It has special effects on crop root rot, dead trees, stiff seedlings, stunted growth, low yield, and poor quality. It is simple and convenient to use and can be mixed with most pesticides, fertilizers, and fungicides. It is a pure biological agent that has no side effects on crops and no residue. Farmers can use it with confidence.
