Economic Benefit Analysis of Ecological Cultivation Model of Rice and Crab in Panshan County
In order to explore the optimal ecological cultivation model of rice and crab,the rice yield and the comprehensive benefits of rice output under conventional rice mono-cultivation(RM),rice and crab ecological cultivation(ERC)and rice and crab ecological cultivation optimization(OERC)in Panshan County were compared and analyzed.The results showed that there was no significant difference in rice yield among the three cultivation modes,and the two ecological cultivation modes of ERC and OERC significantly improved the economic benefits.Compared with ERC,OERC significantly improved the yield and size of crab,effectively alleviated the occurrence of dry wilt,and significantly reduced the lodging rate of rice varieties prone to lodging.It is an optimization model of ecological cultivation of rice and crab that takes into account both economic and ecological benefits.
