摘 要:为阐明稀土叶面肥对江淮丘陵和黄河故道葡萄园节肢动物群落、中性昆虫亚群落和食饵功能团组成的影响,通过系统调查和数学分析得出,稀土元素镧、钕和醋(CK2)对肥东葡萄园节肢动物总群落、植食性昆虫亚群落和捕食性天敌亚群落的物种数、个体数和物种丰富度的影响均不显著。稀土叶面肥对萧县总群落的物种数影响显著,镧对总群落物种丰富度影响显著,其余影响不显著。镧和钕元素对两地葡萄园中性昆虫亚群落的物种数和物种丰富度影响极显著,对个体数影响不显著,CK2对中性昆虫亚群落的物种数、个体数和物种丰富度影响均不显著;肥东县葡萄园镧肥区、钕肥区和CK2与CK1之间食饵功能团物种数的t值为3.4384、2.3911和2.0528,镧肥区和钕肥区与CK2之间食饵功能团物种数的t值为1.6397和0.6357;萧县葡萄园镧肥区、钕肥区和CK2与CK1之间食饵功能团的物种数t值为2.2909、2.3223和0.3674,镧肥和钕肥区与CK2之间的t值为2.7533和2.7744,表明镧肥和钕肥对两地食饵功能团的物种数影响均显著。肥东县镧肥区、钕肥区和CK2与CK1之间食饵功能团的个体数t值为1.3047、1.0338和0.2300,镧肥区和钕肥区与CK2之间的t值为1.6014和1.1835;萧县镧肥区、钕肥区和CK2与CK1之间食饵功能团的个体数t值为1.0431、1.0245和0.7369,镧肥区和钕肥区与CK2之间的t值为0.9495和0.9490;两地处理与与CK1和CK2之间食饵功能团的个体数t值均小于t0.05,表明稀土叶面肥对两地食饵功能团个体数影响不显著。稀土叶面肥对肥东葡萄园食饵功能团物种丰富度影响很小,萧县镧肥和钕肥与CK2之间物种丰富度的t值为2.1709和2.0226,差异显著。综上所述,稀土叶面肥对葡萄园中性昆虫亚群落和食饵功能团的物种数影响显著。To elucidate the influences of spraying rare earth foliar fertilizer on arthropod community,neutral insect sub-community and prey functional groups in grapery,in this work,systematic investigations were carried out in Feidong of Yangtzi-Huai hills and Xiaoxian of Huanghe River old way.Statistically analytical results showed that lanthanum,neodymium and vinegar(CK2) treatments had not significant impacts on species numbers,individual numbers and species richness index of arthropod community,herbivorous insect sub-community and predatory natural enemy sub-community in the grapery of Feidong ( all t values t0.05 = 2.07).However,in the grapery of Xiaoxian,the lanthanum and neodymium treatments had very significant influences on species numbers of arthropod community (t values are 3.2571 and 2.6969,respectively),and Lanthanum treatment had also significant effect on species richness (t value = 2.3956),while lanthanum,neodymium and CK2 treatments had not significant influences on the other indexes.The further statistical analysis demonstrated that the t values of species numbers of neutral insect sub-community between the three fertilizer treatments (lanthanum,neodymium and CK2) and CK1 were,respectively,3.1559,4.0102 and 0.5959;and the t values of individual numbers were,respectively,2.0390,1.7349 and 0.4564;as well as the t values of species richness index were,respectively,4.0491,4.0601 and 1.0310 in the Feidong′s grapery.Whilst in Xiaoxian′s grapery,the t-testing values of species numbers between the three fertilizer treatments and CK1 were,respectively,4.6399,4.9084 and 0;and the t values of individual numbers were,respectively,1.0340,1.0196 and 0.8705;as well as the t values of species richness index were,respectively,3.0646,4.0325 and 0.0784.These above results indicated that,in both Feidong and Xiaoxian,the t values of both species numbers and species richness index between the two fertilizer treatments (Lanthanum and Neodymium) and CK1 were greater than t0.01 = 2.82,displaying that
