根据浙江省科委下达的“贩江淡水虾苗种资源开发利用研究”课题要求,90年代初我们先后在浙江省青田县、遂昌县等地进行稻田养殖青虾试验,经过多年的探索,初步摸清了稻田单养虾及稻田鱼虾混养技术的关键。试验结果表明,稻田养虾可以改善稻田生态环境,在保证水稻产量的前提下单养虾每亩可增收虾38.9 kg,获利700多元,鱼虾混养产虾 15.7 kg,取得显著社会效益和经济效益。现将其技术要点介绍如下。
According to the “Research on Development and Utilization of Freshwater Shrimp Seed Resources in Shaoguan” issued by Zhejiang Science and Technology Commission, in the early of 1990’s, we conducted freshwater shrimp farming in paddy fields in Qingtian County and Suichang County of Zhejiang Province. After years of exploration, Preliminary find out the key to polyculture technology of paddy single shrimp and paddy fish. The results showed that shrimp farming in paddy field can improve the ecological environment of paddy field. Under the precondition of ensuring rice yield, shrimp can increase shrimp 38.9 kg per mu, profit more than 700 yuan and shrimp 15.7 kg shrimp polyculture shrimp, achieved significant social benefits and Economic benefits. Now the technical points are as follows.
