Abstract: 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.
