研究了夏套棉的环境因子及其对棉株生长发育的影响 .结果表明 ,麦棉共生期 ,麦田畦埂棉苗冠层光照强度为单作棉苗的 30 %左右 ,麦套棉行棉苗大部分时间处在光补偿点以下 ,光照是影响夏套棉生长发育诸因子中的首要因子 ;0、5、1 0、1 5、2 0cm深度土壤的日平均温度 ,麦田畦埂比单作棉田分别降低 5.1、4.0、4.6、5.0、4.9℃ ,比麦套棉行分别提高 2 .1、1 .8、1 .1、0 .6、0 .6℃ ;其它环境因子 ,麦田畦埂一般均优于麦套棉行而次于单作棉田 .棉株性状 ,麦田畦埂的优于麦套棉行次于单作夏棉 ;生育期 ,麦田畦埂的早于麦套棉行晚于单作夏棉 ;经济性状 ,麦田畦埂的好于麦套棉行次于单作夏棉 .
The environmental factors and their effects on the growth and development of cotton plants were studied.The results showed that the canopy light intensity of cotton seedlings was about 30% Most of the shoots were below the light compensation point, and light was the most important factor affecting the growth and development of summer cotton. The daily mean temperature of 0, 5, For cotton fields were reduced 5.1,4.0,4.6,5.0,4.9 ℃, respectively, cotton than the cotton line increased by 2.1, 1.8,1 .1,0 .6,0. 6 ℃; other environmental factors, wheat field 畦 埂Generally better than wheat cotton line and secondly in single cotton field.The characters of cotton plant and wheat field were superior to wheat cotton line in the single cotton crop.The growth period was earlier than that of wheat cotton line In a single for summer cotton; economic traits, wheat field is better than the wheat cotton line in a single for summer cotton.
