通过应用免耕、一种两收、旱育抛栽等轻型栽培技术,对鄂东地区“油稻稻”四种轻型种植模式进行研究。结果表明,稻田轻型种植模式与旧模式比较具有省工、低耗、投入少、高产出、高效益等综合优势。油菜免耕直播板栽、水稻软盘抛栽和一种两收轻型栽培技术应用效益明显。 Through the application of no-tillage, a two-cropping, dry cultivation and throwing planting and other light-cultivation techniques, four light planting patterns of “paddy rice” in eastern Hubei Province were studied. The results showed that compared with the old model, the light planting mode in paddy field had such advantages as less labor, less consumption, less investment, higher output and higher benefit. Rape no-tillage broadcast planted rice, rice floppy disk throwing and a two-cropped light cultivation techniques applied obvious benefits.
