在单位面积水田上,一年能收两季稻谷两季鱼的两杂两鱼共生栽培新技术,为有限耕地高产出、高效益的集约经营开发了新的途径。黄冈县1984年开始试验研究,到1987年两杂两鱼共生栽培面积已经发展到2422亩,占全县稻田养鱼面积的15%,占稻鱼共生面积的1/3。通过四年的实践证明,这种栽培法能做到粮食产量稳步增长,经济效益成倍增加,农田生态环境也有明显改善。 一、效益评价 两杂两鱼共生栽培是由原来水田粮油生产“单轨型”转变为种养结合“同轨型”,
In paddy fields per unit area, the two-season and two-fish co-cultivation techniques that can harvest two-season rice in two seasons each year can be used to develop new ways for the intensive management of limited arable land with high output and high efficiency. Huanggang County in 1984 began experimental studies, by 1987 two miscellaneous fish symbiosis cultivation area has been developed to 2422 acres, accounting for 15% of the county rice area fish farming, rice accounted for 1/3 of the symbiotic area. Through four years of practice, it has been proved that this cultivation method can achieve a steady increase in grain output, a double increase in economic benefits, and a marked improvement in the ecological environment of farmland. I. Benefit Evaluation The symbiotic cultivation of two miscellaneous and two fish was transformed from “monorail” of grain and oil production in the paddy field to planting and raising of “same type”
