气候变化对县域棉花物候期影响——以陕西大荔为例
Impacts of climate change on cotton phenophase of a county——Take Dali in Shaanxi Province for example
摘要
Abstract
According to meteorological information in recent SO years and cotton phenological data in last 10 years in the main cotton producing area of Dali County in Shaanxi Province, the methods of linear trend and Mann - Kendall inspection were used to analyze the trend of climate and cotton phenological change and the impacts of climate change on cotton phenophase. The results revealed that, in recent 50 years, the average temperature increased considerably , while precipitation decreased slightly, sunlight hours increased, and the trends of extremely low and high temperature were not in synchronization, extremely high temperature dropped, while extremely low temperature rose slightly. Temperature and sunlight hours were the main weather factors to cotton phenophase. The climate turned wanning and drying, and sunlight hours increased in last 10 years, which made cotton phonological phase (from seedling period to harvest period) partly advance with different levels, and the seedling period and harvest period showed the most significant advance, which resulted in the extension of cotton growth period and was conducive to improving the quality of cotton.关键词
