摘  要：
在稻蟹种养模式下,采用田间试验方法系统研究了稻蟹联合种养对水稻田生态环境和经济效益的影响.结果表明,与常规施肥(FP)相比,氮肥减量配合环保型聚天门冬氨酸肥料可显著降低水稻田面水中NH4+-N和NO3--N含量,对稻田阔叶杂草具有很好的控草效果,水稻产量略有提高.稻蟹联合种养生态模式可减少无机化肥和农药的施用量,因此实施扶持稻田联合种养结合循环农业模式策略,是改善稻区农业生态环境的重要途径,具有显著的经济效益和生态效益.

摘  要：
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. Results 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 production. This research exploits an agricultural model for a broader ecological and evolutionary perspective into research 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.
