研究两种氮肥水平条件下麦蚜天敌群落生物多样性差异 ,结果表明其差异不显著 ;同时分析了两种肥力水平对两种麦蚜空间格局的影响 ,结果表明其影响不显著
The results showed that there was no significant difference in the biological diversity of the natural enemies of wheat aphids under the two nitrogen levels. The effects of the two fertility levels on the spatial pattern of the two kinds of wheat aphids were also analyzed. The results showed that the effect was insignificant
