Differential regulation of soil microecology in crop rotation systems of maize, seed pumpkin, and processing tomato.

ABSTRACT: Long-term continuous cropping of processing tomatoes in Xinjiang has led to soil degradation and microecological imbalance, severely constraining the sustainable development of the industry. To investigate the mitigation mechanisms of different crop rotation systems, this study established maize-tomato rotation (SZa), pumpkin (for seeds)-tomato rotation (SLa), and continuous cropping control (SSa) treatments in a long-term continuously cropped tomato field. The results demonstrated that compared to SSa, the SLa treatment increased the proportion of large aggregates (>2 mm) by 16.5%, whereas the SZa treatment decreased it by 24.6%. Rotation significantly reduced soil pH (by 5.6%-6.0%) and increased electrical conductivity (by 124%-215%). Enzyme activities responded variably: phosphatase act
