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。
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.
