Effects of rice-crab coculture on rice growth and paddy field ecosystem:A review
The rice-crab coculture model,as a distinctive rice field cultivation and breeding mode in Chi-na,relies on mutual benefits between species and complementary utilization of resources in rice field.It plays a significant role in maintaining soil fertility and rice yield,improving nitrogen use efficiency,and controlling pests,diseases,and weeds.In this paper,we mainly summarizes and analyzes the impact of the rice-crab coculture model on rice field ecosystems from five aspects,rice growth,water quality,soil environment,system nitrogen loss and biodiversity.The main conclusion is that the rice-crab coculture model can stabilize or increase rice yield and improve rice quality although its impact on the rice field ec-ological environment is complex.Our findings provided a reference for the in-depth development and promotion of rice-crab co-culture model.
