Fig. 3From: Effects of plastic film mulching and legume rotation on soil nutrients and microbial communities in the Loess Plateau of ChinaEffect of different film mulching and crop rotation treatments on bacterial and fungal alpha diversity. a, c, e Chao1, ACE, and Shannon indices for bacteria. b, d, f Chao1, ACE, and Shannon indices for fungi. Different lowercase letters indicate a significant difference between treatments (p < 0.05). Film mulching (F), crop rotation (R), interaction of film mulching and crop rotation (F × R). *p < 0.05, **p < 0.01, ***p < 0.001. PC, potato continuous cropping without film mulching; PCF, potato continuous cropping with film mulching; R1, potato–broad bean rotation without film mulching; R1F, potato–broad bean rotation with film mulching; R2, potato–pea rotation without film mulching; R2F, potato–pea rotation with film mulchingBack to article page
