作物复种的免耕直播栽培研究进展

综述了国内外水稻、油菜等作物复种的免耕直播栽培技术的发展,免耕稻田土壤的物理化学特性及生物特征,免耕直播栽培对作物生长发育及产量的影响,以及适合于我国水稻-油菜复种的免耕直播栽培的技术。指出作物免耕直播与翻耕移栽具有同样的产量潜力,省工、节本、增效的效益显著,是我国作物低成本、高效益栽培的主要途径之一。

Research Development of Direct Seeding and Zero-tillage Cultivation in Multiple Cropping Systems

This paper reviewed the development of direct seeding and zero-tillage cultivation in multiple cropping systems, physical, chemical and biological characters of zero-tillage paddy soils, the effects of direct seeding and zero-tillage on the growth development and yield and adaptable techniques for direct seeding and zero- tillage cultivation in rice-oil rape system. This paper also pointed out that the direct seeding and zero- tillage has the same yield potential and more beneficial and needs less labors compared traditional transplantation under pollowed paddy soils. A possible path is of crop cultivation of low input and high profit in China.
