Abstract: The large quantities of 100% straw covered fields in the annual double cropping system affects the operation of the no-till planter, which had been influenced the crop emergency. The effects of 6 different kinds of treatments on soil water content, plant growth characteristics and plant yields was researched in this study. The results showed that the problems of blocking under large amount of straw, seeds airing were solved under biochar covers in no-tillage treatment. Compared to straw covers in no-tillage treatment, the water content of biochar covers with no-tillage treatment was lower, in contrast, plant growth characteristics such as crop emergency and plant height and plant yields were increased. The results in this study can promote the extension and development of conservation tillage.
