摘要
采用随机区组设计,设渗水地膜覆盖、普通地膜覆盖和露地三个处理,研究了不同处理对高粱生育期和产量的影响。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)渗水地膜覆盖高粱每公顷穗数、穗粒重、千粒重、穗长、穗粗、经济系数明显高于普通地膜覆盖和露地。(3)渗水地膜覆盖较普通地膜覆盖和露地产量差异达0.01显著水平,比露地增产20%以上。
The experiment design was randomized blocks about three treatments including water-permeability plastic film mulching,common plastic film mulching and open ground.The experiment studied growth season and yield of different treatments on sorghum.The result had showed:1)The water-permeability plastic film mulching promoted the growth and development of sorghum,so sorghum could mature earlier.2) The ear number per hectare,the grain weight per ear,1000-grain weight,economic coefficient,spike length and spike wi...
