北疆棉区棉花生长期气候变化特征及其对棉花发育的影响
Climatic change during Apr. to Oct. in recent 47 years and its effects on growing period of cotton in Beijiang cotton planting region
摘要
Abstract
The data of four weather stations during Apr. to Oct. from 1961 to 2007 in Beijiang cotton planting region were analyzed using the climatic tendency coefficient, and the characteristics of climate change during cotton growth were also analyzed. The results were as follows: the temperature and the precipitation had been increasing, but the duration of sunshine decreasing. The date of the latest frost appearing was getting earlier and the date of the first frost was postponed. The 1O℃ beginning date was getting earlier and the 1O℃ ending date was postponed. The duration and accumulated temperature( ≥ 10℃ )all were increasing. Contrasted with the data of cotton growing date since 1991, each growing stage from seeding to split boll period of cotton became earlier and the growing period was delayed, and the whole growing season of cotton was delayed too. Wanner climate is advantageous to the cotton production in Beijiang cotton planting region.关键词
