摘要
2007年在浙江省绍兴县采用水稻和青虾轮作种养模式试点,试验面积为8.4hm2,4月5～8日播种水稻,7月19～27日收割,8月5～17日放养青虾苗种,12月底捕捞,试验共收获水稻50400kg,获利38052元;青虾5670kg,获利151200元;鲢鳙16758kg,获利14868元,总获利204120元,投入产出比为1∶1.698。试验表明,稻虾轮作种养模式作为农民增收有效途径具有重要的推广价值。
In 2007, the experiment of rice - shrimp rotation farming was carried out in Shaoxing County. The trial area was approximately 8.4hm2 and the rice was planted between April 5 and 8. After the harvest of the rice between July 19 and 27, the freshwater Shrimp fry was stocked on August 8 - 25. At the end of December the freshwater shrimp （Macrobrachium nipponense） was fished. The output of rice was 50 400 kg, which make a profit of 38 052 yuan; the yied of freshwater Shrimp was 5 670kg, which earn 151 200 yuan; the production of Silver carp and Bighead crap was 16 758 kg, which also make a profit of 14 868 yuan. As a result, the total profit was 204 120 yuan and the proportion of input to output was 1 ： 698. These show rice-shrimp rotation farming model has an important promotional value as an effective way to increase the income of farmers.
