1990-2020年南疆阿拉尔垦区棉花物候期的动态变化
Dynamic Changes of Cotton Phenological Stages in Alar Reclamation Area of Southern Xinjiang from 1990 to 2020
摘要
Abstract
Phenology is the sensor of climate change,which can objectively reflect the impact of climate change on cotton growth cycle.In order to explore the dynamic changes of cotton phenological stages in Alar reclamation area of southern Xinjiang under the background of climate warming and humidification,the cotton phenological stages data were selected and the statistical methods such as anomaly,cumulative anomaly,Mann-Kendall nonparametric test and sliding t test were used to analyze the dynamic changes and abrupt changes of cotton phenological stages in Alar reclamation area of southern Xinjiang from 1990 to 2020.The results showed that the average cotton sowing stage,seedling stage,squaring stage,flowering stage,boll opening stage and stopping growth stage appeared on April 14,April 29,June 3,July 2,September 17 and October 20,respectively,which the range were 25,23,20,22,44 and 24 d,respectively,in Alar reclamation area of southern Xinjiang from 1990 to 2020.The cotton sowing stage and seedling stage showed a very significant advance trendy with"significantly advanced-slightly advanced"process change.The flowering stage and stoping growth stage showed a significant advance trendy with"significantly advanced-slightly advanced"process change.And the advanced of the boll opening stage and the delayed of the squaring stage showed no significant changes.The characteristics of cotton squaring stage,flowering stage and boll opening stage were obvious which mainly delayed of squaring stage,advanced of boll opening stage,the delayed and advanced of flowering stage in Alar reclamation area of southern Xinjiang from 1990 to 2020.And the characteristics of stage changes in sowing stage,seedling stage and stoping growth stage of cotton were not obvious in Alar reclamation area of southern Xinjiang from 1990 to 2020.The results could provide theoretical basis for better evaluation of cotton growth and scientific management of cotton field in reclamation area under the background of warming and humid climate.关键词
