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.
