Abstract
The experiment design was randomized blocks with three treatments including water-permeability plastic film mulching,common plastic film mulching and open ground.The experiment focused on the development of different treatments on sorghum.The result has showed:(1)The water-permeability plastic film mulching promoted the growth and development of sorghum,so sorghum could mature earlier.(2) The water-permeability plastic film mulching promoted the second roots growth and increased the second root number,it accelerated leaf growth and made plant high.(3)The water-permeability plastic film mulching increased the number of plant leaf,and its leaf area was larger in middle and lower leaves,so its LAI was bigger than the other two treatment's.
