摘  要:
在大田实地观测的基础上,对地下滴灌水分变化、棉花各生育阶段蒸腾量进行测定,同时取棉花根系观察,结果表明:地下滴灌棉田土壤水分变化深度主要在20-60cm;棉花根系分布在10-80cm范围,主要集中在15-50cm,并且有两个明显的根系层;博乐垦区棉花日均耗水量苗期为1.4mm/d,蕾期为2.3mm/d,花铃期为3.8mm/d,絮期为1.5mm/d,并由此制定该地区的灌水制度。

摘  要:
This paper analyzed moisture change and cotton on the foundation of the big field observation on-the-spot, for underground drop give birth to stage each to rise, quantity is surveyed, at the same time, cotton root is observed, The result is: underground drop fill the soil moisture change depth of cotton field major in 20-60 cm; cotton is thoroughly spread in 10-80 cm scope, major concentration in 15-50 cm, and have two obvious root departments layer; the rich happy cotton of reclamation area day the seedling stage of water consumption is 1.4 mm/d, bud stage is 2.3 mm/d, blooming and fruiting stage is 3.8 mm/d, boll opening stage is 1.5 mm/d, fill water system by this established this region.
