在综合开发利用冬水田的工作中,我县部分地方把前几年的稻—笋、稻—鱼、稻—萍利用方式,结合成稻—笋—鱼—萍综合种养的立体结构,取得了显著效益。一般亩产稻谷500—600公斤、鲜笋600—800公斤、鲜鱼50—80公斤、绿萍4,000—5,000公斤。亩产值达到700—800元,比水稻净作增收约3倍,比稻—笋或稻—鱼套作增收1倍以上。这种结构能充分利用光、温、水、土资源,培肥土壤,互相利用和促进,可显著提高经济效益和生态效益。稻—笋—鱼—萍立体种养,应着重抓好以下技术环节:
In the comprehensive development and utilization of winter paddy fields, some parts of our county have made use of the three-dimensional structure of rice-shoots, rice-fish, rice-duck utilization in the past few years in combination with the comprehensive planting and breeding of rice-shoots-fish- Significant benefits. General per mu rice 500-600 kg, 600-800 kg fresh bamboo shoots, fresh fish 50-80 kg, 4,000-5,000 kg Greenpine. The output value per mu reached 700-800 yuan, about three times more than the net increase of rice and more than one time more than that of rice-shoots or rice-fish sets. This structure can make full use of light, temperature, water, soil resources, soil fertility, mutual use and promotion, can significantly improve economic and ecological benefits. Rice - shoots - fish - Ping three-dimensional planting and breeding, should focus on the following technical aspects:
