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。

Abstract:

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.

Key words: Shihezi cotton region of northern Xinjiang, cotton lodge, meteorological factors
