| 摘 要： | 采用田间试验方法，研究了稻-蟹-泥鳅田生态系统的效益。结果表明：稻-蟹-泥鳅田饵料转化率在16．57％-18．34％之间．比稻-蟹田13，61％提高2．96％-4．73％。1hm^2稻-蟹-泥鳅田产出无公害水稻9111kg、无公害河蟹474kg，分别与稻-蟹田水稻9200kg和河蟹489．6kg相近。增收无公害泥鳅145，8kg，经济效益比稻-蟹田14458元增加1015．6元。其中养泥鳅利润为1191．11元。

| Abstract: | This paper analyses the benefit of the paddy, crab and loach field ecosystem through experiment. The results showed that the transformation ratio of diet was between 16.57% and 18.34% in paddy, crab and loach field, The yields of rice and crab were similar in both systems, but the additional 145.8kg loach per hm^2 was harvesfed in paddy, crab and loach system, The benefit in paddy, crab and loach field per hm^2 was 1015.6yuan, and that in paddy and crab field was 14458yuan. The benefit of loach was 1191.11yuan. |
