Research Progress on Nutrient Regulation Technology on the Reduction of Soybean Continuous Cropping Barrier
In order to clarify the effect of different nutrient regulation technologies on the reduction of soybean continuous cropping obstacles,this paper expounds the occurrence and harm of soybean continuous cropping obstacles.In this paper,the solutions for different hazards in soybean continuous cropping obstacles were reviewed from three aspects:Improving fertilizer nutrient supply capacity,improving soil physical and chemical properties,and optimizing soil microbial environment.The problem of long-term continuous cropping of soybean causing nutrient depletion in the soil and affecting the growth and development of soybean was solved by changing the fertilization method,time and quantity.By using different amendments,the problems of soil acidification,compaction,and the decline of water and fertilizer retention capacity can be solved.Beneficial microorganisms were introduced into soybean continuous cropping soil,so as to reduce the activity of harmful microorganisms and pathogenic bacteria,and finally achieve the effect of improving the soil microbial environment.Finally,it is concluded that the problems to be solved in the process of reducing soybean continuous cropping obstacles and the research direction of nutrient regulation technology were summarized to provide suggestions and prospects for the research on the occurrence and development mechanism of soybean continuous cropping obstacles and the optimization and improvement of nutrient regulation technology.
