摘要
以郑麦9023为试验材料,研究了2种保护性耕作技术对小麦分蘖数、穗粒数、千粒重、产量等指标的影响。试验结果表明,秸秆粉碎还田深耕的效果最好,有利于小麦的生长发育并能提高产量;而秸秆还田免耕对小麦生长发育及产量有不良影响。
In order to study tillage effects on wheat yield,Zhengmai 9023 had been selected as test material,two conservation tillage cultivating technologies had been examined on wheat tiller number,grain number,grain weight,yield and other indexes. The results showed that straw chopper deep plowing was the best for the growth of wheat and to increase production. No-tillage on wheat straw had an adverse effect on growth and yield.
