Responses of Rhizosphere Soil Physicochemical Properties and Enzyme Activities to Polyethylene Microplastic Stress in Maize–Soybean Intercropping
Agricultural microplastics threaten soil health, yet rhizosphere microecological responses to microplastic stress in intercropping systems remain unclear. We conducted a pot experiment using two cropping systems (maize monocropping and maize–soybean intercropping) and four polyethylene microplastic (PE-MP) levels (0%,...
