图3 不同年份和不同处理间土壤线虫群落不同营养类群的密度。VV: 光叶紫花苕; MS: 紫花苜蓿; CK: 对照。F表示牧草间效应, Y表示年间效应, F × Y表示牧草与年间的交互效应。F为参数检验, H为非参数检验。不同大写字母表示不同处理间差异显著(P < 0.05), 不同小写字母表示同种处理不同年份间的差异显著(P < 0.05)。

Fig. 3 Density of different trophic groups of soil nematode communities in different cultivating years and different treatments. VV, Vicia villosa; MS, Medicago sativa; CK, Control. F represents the effects of forages, Y represents the effects of cultivating years, and F × Y represents the interactional effects of forages and cultivating years. F represents the parameter test, H represents the nonparametric test; Different capital letters represent the significant difference between treatments (P < 0.05), and different lowercase letters represent the significant difference between the different cultivating years (P < 0.05) of the same treatment.
