稻蟹联合种养对稻田生态环境的影响
Effect of Rice-crab Co-culture on Environment of Rice Field
摘要
Abstract
A field study was conducted to investigate the effect of rice-fish poly-culture on the concentration of nitrate nitrogen and ammonium nitrogen, weed and yield of rice and crab under different nitrogen dose.Re-sults showed that the concentration of nitrate nitrogen and ammonium nitrogen was significantly decreased by minimize nitrogen application in co-culture treatment.Compared with the traditional mono-rice plant model, the existence of crab in the rice-fish poly-culture was beneficial to the rice yield.It could dramatically reduce the need of the chemical inputs such as pesticide and fertilizer while sustaining high and stable grain produc-tion.This research exploits an agricultural model for a broader ecological and evolutionary perspective into re-search on rice plant area.Therefore, rice-fish poly-culture could contribute agriculture at a large scale by the ecological interaction between plant, crab and the environment.关键词
