Abstract
The field experiment was conducted to study the effect of different tillage models(conventional tillage,deep tillage+straw returning,deep tillage+straw returning,and every other year deep tillage+straw returning)on the leaf area index,grain filling rate and yield of summer maize.The results showed that deep tillage+straw returning could significantly increase the leaf area index,promote the grain filling rate,and improve the grain yield by 4.48%-6.65%compared to the conventional tillage+straw returntng.Without straw returning for 2 years,the gain yield decreased.The highest yield was from the continuous deep tillage+straw returning,which gave an average yield increase of 6.48% in two years.
