根据泽普县1961—2015年平均气温、降水量、日照时数等气象观测资料,利用气候学方法对泽普县近55年来光热气候条件的变化特征进行分析,研究气候变化与红枣产量相关关系。结果表明:泽普县气候变化总体呈平均气温上升、降水量增多、日照时数增加趋势。降水量与红枣产量正相关性显著,尤其花期降水对开花、授粉较有利;坐果期到成熟采收期跟气温成正相关,跟降水成负相关;花期和成熟期日照时数与产量成正相关。
Based on the meteorological observation data of average temperature, precipitation and sunshine hours from 1961 to 2015 in Zepu County, climatological methods were used to analyze the characteristics of solar thermal climatic conditions in Zepu County in recent 55 years, and to study the relationship between climate change and yield of red dates relationship. The results show that the overall climate change in Zepu County shows an average temperature increase, an increase in precipitation, and an increase in the number of sunshine hours. Precipitation was positively correlated with jujube yield. In particular, flowering was more favorable to flowering and pollination at flowering stage. Positive correlation between precipitation and mature temperature was positively correlated with temperature and negatively correlated with precipitation. There was a positive correlation between flowering and maturity sunshine hours and yield.
