【摘要】 为了明确棉花秸秆还田对棉花植株生长和土壤的影响，本研究通过整合分析前人研究，总结发现棉花秸秆还田可以促进棉花生长、提高棉花产量、改善土壤物理性质、提高土壤中营养元素和有机质的含量、增加土壤微生数量、促进土壤细菌的活性和酶的活性。此外，秸秆还田目前还存在一些问题，如：哪种还田方式更为高效、适宜的还田时间、还田量及如何预防还田带来的毒害问题等。最后，本研究针对现存问题提出了相应建议，以期为棉花秸秆还田高效利用和棉花产业绿色可持续发展提供理论支持。更多还原

【Abstract】 In order to clarify the impact of cotton straw returning on cotton plant growth and soil, the study summarized previous studies and found that cotton straw returning could promote cotton growth, improve cotton yield, ameliorate soil physical properties, increase the content of nutrient elements and organic matter in soil,raise the number of soil microorganisms, and promote the activities of soil bacteria and enzymes. In addition,there are still some problems in cotton straw returning, such as choosing more efficient ways, appropriate returning time, returning amount and preventing toxicity caused by returning. Finally, this study put forward corresponding suggestions for the existing problems in order to provide theoretical support for the efficient utilization of cotton straw and the green and sustainable development of cotton industry.更多还原
