摘要
花生田分别采用免耕清理秸秆、免耕秸秆还田、翻耕秸秆还田、休耕田、翻耕清理秸秆五种耕作方式来进行田间比较试验。结果表明,在不同耕作方式下,以免耕秸秆还田处理花生蛴螬(Holotrichia diomphalia)数量最多,为每平方米12.8头,其次是免耕清理秸秆处理每平方米11.4头,以休耕田处理蛴螬数量最少,为每平方米8.6头,虽然各不同处理花生田间蛴螬的数量不相同,但各处理间蛴螬数量差异不明显。其中以免耕秸秆还田处理经济效益最优。
In order to investigate the effects of different tillage managements on white grubs occurrence and yield of peanut,five different tillage methods including no-tillage with straw cleaning(NSC),no-tillage with straw incorporated(NSI),tillage with straw incorporated(TSI),tillage with straw cleaning(TSC) and fallow(F) were conducted.The results showed that the numbers of white grubs differed with different tillage methods.There were 12.8,11.4 and 8.6 grubs per square meter in NSI,NSC and F treatment,respectively.The number of grubs in all five treatments was higher than control threshold and had no significant difference among treatments.Taking TSC as control,the economic benefit of NSI was the highest.
