【摘要】 麦套春棉和纯作春棉覆膜栽培与纯作春棉露地栽培比较结果表明,三者在不同深度的土壤温度、棉苗冠层光照强度、地面蒸发量、田间湿度和生育期、单株性状及经济性状等方面均有较大差别。麦棉共生期是影响棉苗生长直至中、后期发育的主要时期,热量是影响棉苗生长发育的首要环境因子。更多还原

【Abstract】 Results from conventional and inter-cropping cotton with wheat with film cover or without the film showed that there were great differences among those treatments in soil temperature, soil evaporation,light intensity over cotton canopy, field humidity,growth period, plant characters, economic features, etc.. The length of the co-growth period of cotton with wheat is the main factor affecting cotton seedling growth,even its later growth. Heat is the main environmental factor affecting cotton seedling growth.更多还原
