摘要
在对新疆石河子棉区乌兰乌苏和莫索湾两个观测点27a的农业气象观测资料进行分析的基础上,对这两个测点棉花植株倒伏进行2 a平行观测,在排除品种、栽培措施、土壤性质和肥力等非气象因子以后,初步得出结论:石河子棉区棉株倒伏的关键时期是花铃期;造成石河子棉区棉株倒伏的主要气象因子是0—30 cm土壤相对湿度和当时的风速及持续时间。
Analyses on agrometeorological observation data for 27 years from Wulanwusu and Mosuowan weather stations in northern Xinjiang were conducted, and another parallel observation for 2 years about cotton lodge was done at two observation sites. It was disclosed that the key factors effecting cotton lodge are meteorological factors, mainly including soil relative humidity within 0--30 cm layer, and temporal wind speed and its duration. Cotton lodging frequently happened in bloom-kell period. Non-meteorological factors such as plant variety, culturing steps, soil property and its fertility, etc. have no effect.
