【Abstract】 By comparing the difference of soil physical property and soil temperature, the loss of field water and soil nutrient, plant growth and yield between irrigation with plastic mulch and the traditional irrigation it indicated the effect with plastic mulch on soil environment and plant growth, and showed that irrigation with plastic mulch can improve soil environment, decrease the loss of invalid soil water,advance plant growth .So irrigation with plastic mulch is an important measure to add the profit and decrease the cost in the course of cotton production.更多还原
