河蟹作为水产珍品,自古以来,就被人们誉为上等菜肴,但市场货紧价昂,供不应求。近年来,一些农户开展了河蟹人工养殖,获得了成功,取得了一定经济效益。1988年以来,我们根据城郊农业要“为城市服务”的要求,针对免耕旱直播畦作中稻面积逐年扩大的实际,为合理利用稻田一套沟,提高稻田单位面积土地生产力,开展了稻田养蟹配套技术的研究,并于1990年底,通过专家鉴定。从研究和示范推广结果看;稻蟹共生的生态结构,既适合河蟹生活习性的要求,又有利于水稻生产。具有
Crab as a treasure of aquatic products, since ancient times, has been hailed as the finest dishes, but the market tight prices, demand exceeds supply. In recent years, some farmers have carried out artificial breeding of crab and have achieved success and achieved certain economic benefits. Since 1988, according to the request of suburban agriculture to serve the city, in view of the fact that the area of mid-season non-tillage and direct seeding cultivation has been expanding year by year, in order to make rational use of a set of furrows in paddy fields and improve land productivity per unit area in paddy fields, Crab supporting technology research, and by the end of 1990, through expert identification. Judging from the research and demonstration results, the ecological structure of rice-crab symbiosis is not only suitable for the habitat requirements of crabs, but also conducive to rice production. have
