水稻冬闲田白菜薹免耕栽培效益研究

Experiment on No-Tillage Cultivation of Chinese Cabbage in Rice Winter Fallow Fields

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%。

This paper comparied one-season paddy field Chinese cabbage production between no-tillage and tillage cultivation, which studied the effect of no-tillage on plant survival rate, pest situation, production cost, yield and efficiency. The results showed that no-tillage cultivation of Chinese cabbage reduced cutworms damage rate and production costs, but the yield and value declined. The yield of no-tillage cultivation decreased by 10.3% and 11.9% compared with mechanical and manual plowing cultivation. And the production efficiency of no-tillage cultivation decreased by 11.9% compared with mechanical plowing cultivation, but increased by 11.1% compared with manual plowing cultivation.
