不同耕作方式对夏玉米生长发育及产量的影响
Effect of Different Tillage M ethods on Grow th and Yield of Summer M aize
摘要
Abstract
The field experiment was conducted to study the effect of different tillage models (convention-al 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 return-tng .Without straw returning for 2 years ,the gain yield decreased .The highest yield was from the contin-uous deep tillage+straw returning ,w hich gave an average yield increase of 6 .48% in tw o years .关键词
