| 摘 要： | 试验采用渗水地膜覆盖、普通地膜覆盖和露地三个处理的随机区组设计,研究了不同处理对高粱生长发育的影响。结果表明:(1)渗水地膜覆盖明显加快了高粱的生长发育进程,使高粱提早成熟。(2)渗水地膜覆盖促进了高粱次生根的生长,增加了高粱次生根条数;加快了高粱叶片的生长速度,使高粱的株高增长稳定。(3)渗水地膜覆盖后,增加了单株叶片数,其中下部叶片叶面积较大,使其在抽穗前叶面积指数大于其它两处理。

| 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. |
