摘要
通过对杂交棉＂湘001＂开花及脱落记载,研究棉花不同果节位及不同时期的蕾铃脱落规律,并结合天气情况分析杂交棉蕾铃脱落与天气的关系。结果表明：杂交棉不同果节位的脱落规律为自下而上、自内而外脱落率逐渐增高;7月21~30日落蕾率较高,8月10~19日落铃率较高;开花后11天内的幼铃最容易脱落。脱落对天气有滞后反应,气候因子中高温与强降水对脱落影响最大。
Based on observation of flowering and shedding of hybrid variety ＂Xiang 001＂,the shedding pattern of boll and bud on different position and time were studied.Relationship between shedding and weather was also analyzed.The results indicate that shedding rate is up from bottom to top and from inner to outer,and bud-shedding rate is higher between 21st and 30th in July,and boll-shedding between 10th and 19th in August.Boll grown less 11 days after flower is apt to shedding.Shedding response lagged behind weather.High-temperature and heavy-precipitation have strong influence upon shedding.
