通过对一季稻田白菜薹免耕与翻耕栽培试验对比,研究了冬闲田白菜薹免耕栽培对植株成活率、虫害情况、生产成本及产量与效益的影响。结果表明,免耕栽培可减轻白菜薹的地老虎危害率,降低生产成本,但产量和产值有所下降。免耕栽培产量比机械翻耕和人工翻耕免耕栽培分别降低10.3%和11.9%;生产效益比机械翻耕栽培降低11.9%,比人工翻耕栽培提高11.1%。
By comparing the no-tillage and tillage cultivation trials of Chinese cabbage boll in the first season paddy field, the effects of no-tillage cabbage boll culture on plant survival rate, insect pest, production cost, yield and benefit were studied. The results showed that no-tillage cultivation could reduce the damage rate of the native tiger to the cabbage boll and reduce the production cost, but the output and the output value decreased. The yield of no-till cultivation was reduced by 10.3% and 11.9% respectively compared with that of mechanical tillage and manual tillage; the productivity was 11.9% lower than that of mechanical tillage and 11.1% higher than that of artificial tillage.
