Principal coordinate analysis of a bacteria and b fungi (operational taxonomic units > 0.01%) under different film mulching and crop rotation treatments. The sample groups show 95% confidence ellipses for each treatment. 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 mulching
