石河子棉区棉花阶段延迟型冷害指标研究
The Research of Cotton Delayed Cool Injury Index in the Cotton Region of Shihezi
摘要
Abstract
To objectively assess the damage to cotton by low temperature, the field experiment of sowing seeds by stages was conducted respectively in the Mosuwan and Wulanwusu Agro- meteorological Station in the cotton growth seasons from 2003 to 2007. The different agricultural characteristics were measured such as the growth stage, leaf and flower, yield and fruit branches of cotton. In the meantime, several meteorological factors such as light, temperature and humidity were monitored and recorded continuously. To research impact of low temperature on growth and quality of cotton during the flowering and boll stages, the regression equation of yield and the interval days from blooming to bloom filling stage were analyzed. The index of interval days, single boll weight and the flower percentage before frost were confirmed from blooming to bloom filling stage, which could be the assessment index of different levels of delayed cold damage. In the same way, the light, medium and heavy levels of the single boll weight index about delayed cold damage from the flowering to the crack time in cotton region in north Xinjiang could be built as well.关键词
