摘要
比较了南湖菱套养泥鳅与单作南湖菱的产量及效益情况,并提出了科学的南湖菱套养泥鳅技术要点。结果表明,南湖菱套养泥鳅与单作南湖菱相比,菱产量降低200.25 kg/667m2,增加泥鳅产量209.25 kg/667m2,产值增加8005.50元/667m2,成本增加6305元/667m2,效益增加1695.50元/667m2,另外,套养泥鳅还可减少杀虫剂的使用次数及使用量,因此南湖菱套养泥鳅是一种经济、高效、安全、生态的种养结合模式。
In this paper, we compared the yield and benefit of Trapa acornis--loach planting-raising mode and monocuhure T. aeomis mode, and pointed out technical key points for the planting-raising mode. The results showed that, compared with the monoculture T. acornis mode, the yield of T. acomis decreased by 200.25 kg/667 m2, and costs increased by 6 305 Yuan/667 m2, but the loach yield increased by 209.25 kg/667 m2. Thus, the output value increased by 8 005.50 Yuan/667 m2, and the benefit increased by 1 695.50 Yuan/667 m2. In addition, raising loaches in T. acomis field could reduce the use frequency and use amount of pesticides, therefore the t. aeomis-loach planting-raising mode was an economic, efficient, safe and ecological fanning mode.
