摘　　要： Study shows that mulching of jute geotextiles can greatly improve the tolerance of soil to the changes of atmosphere temperature,and cut down the duration and accumulation quantity of the soil temperature higher than 30℃ and lower than 5℃,which has an inhibiting effect on ramie growth.At the same time,it raised water containing quantity 0.04%～5.83% higher than the soil of bare land.The time when ramie plantlets covered with geojute come out of the soil is shortened,the emergence rate increases 53 percent point.The stem height in the plot with covering geojute increases 25.6～46.4cm in all three growing perods of one year.Furthermore,the number of greenery and overall leaves from emergence to harvest of a ramie are always greater,the crop growing duration extends.Not only the biological yield and the fiber rate from stem but also the fiber yield and economic coefficient are increased.
