南疆地区气温变化及其对红枣产量的影响
Air Temperature Change in Southern Xinjiang and Its Influence on Jujube Yield
摘要
Abstract
Through analyzing the change trends of annual mean temperature and mean temperature at each growth stage of jujube in Aksu , Hotan and Kashgar , southern Xinjiang , from 1990 to 2011 , the effect of air temperature on yield and the contribution to yield change of jujube were studied .The annual mean temper-ature and the mean temperature at each growth stage of jujube in the 3 regions increased in the tested 22 years.The annual mean temperature and the mean temperature at sprout -anthesis and fruit enlargement -maturity periods were all significantly correlated to the yield of jujube , which indicated that air temperature rise was the major reason for increasing jujube yield .Empirical analysis of random effect model showed that the contribution rate of air temperature on jujube yield change was 7 .54%.The jujube yield increased by 9%~11 .7%with every 1℃increase of annual mean temperature .关键词
