摘要
为提升黔北地区稻田综合种养的经济效益和生态效益,2016-2018年连续3年在湄潭县大庙场村实施"稻虾共生"绿色增产增效示范,示范面积33. 3 hm2。结果表明,稻虾模式与传统单季稻模式相比,水稻产量同期下降10%左右,但均价和产值均翻了一番,田间施肥量减少42. 8%～50%,施药次数和种类也大幅减少,产出投入比显著增加,稳产、增收、增效显著,取得了良好的示范效果。
In order to improve the economic and ecological benefits of integrated rice field planting and raising in northern Guizhou,the demonstration of“Rice-crayfish symbiosis”green production and efficiency enhancement was carried out in Damiaochang village of Meitan county from 2016 to 2018.The demonstration area was 33.3 hm^2.The results showed that compared with the traditional single-cropping rice model,rice yield decreased by about 10%in the same period,but the average price and output value both doubled,the fertilization amount in the field decreased 42.8%~50%,the number and type of application decreased significantly,and the ratio of output to input increased significantly.Steady production,increase in income,significant increase in efficiency,and achieved a good demonstration effect.
