| Abstract: | In rice-crab-loach field,the feed transformation rate ranged from 16.57% to 18.34%,increasing 2.96% to 4.73% than that in rice-crab field;in rice-crab-loach field,the yields of non-contaminated rice and crab were 9 111 kg/hm2 and 474 kg/hm2,close to the yields of rice and crab in rice-crab field,9 200 kg/hm2 and 489.6 kg/hm2;furthermore,the non-contaminated loach yielded 145.8 kg/hm2,and the profit was 1 191.11 yuan;generally,the benefit in rice-crab-loach field was 1 015.6 yuan than that in rice-crab field. |
