研究结果表明,高寒山区玉米地膜覆盖对增产有明显效果,其原因主要表现在,增温、增湿、增叶、增穗、增粒,并通过偏回归系数测定,确认高寒山区地膜覆盖后增产的主要效应是增株、增穗。
The results showed that maize mulching in high and cold mountainous area had obvious effect on yield increase. The main reasons were: increasing temperature, increasing humidity, increasing leaf, increasing ear and increasing grain, and confirming the increase of yield after alpine mulching The main effect is by strains, by ear.
