摘要
分别采用免耕秸秆还田、翻耕秸秆还田、免耕清理秸秆、翻耕清理秸秆四种耕作模式来进行田间比较试验。结果表明:在不同耕作模式下,大豆田间蛴螬的数量各不相同,以免耕秸秆还田最高,每平方米蛴螬可达10头以上,以翻耕清理秸秆最低,每平方米蛴螬数量在3头以下。以翻耕清理秸秆作为对照,经济效益以翻耕秸秆还田最优,且比对照每公顷多收入661.23元;其次为免耕秸秆还田,与对照相比每公顷多收入424.01元。
The experiment in soybean field was using these methods：no-tillage,tillage,cleaning straw and no-tillage,and cleaning straw and tillage.The results showed that the numbers of white grubs were different in different tillage systems＇soybean field.There were 10 grubs per square meter in no-tillage,but there were only 3 grubs per square meter in cleaning straw and tillage.By using cleaning straw and tillage as a control,the tillage improved 661.23 Yuan per hectare than the control;and the no-tillage improved 424.01 Yuan per hectare than the control.
