The analysis of main agro-meteorological disasters affecting on the productivity of red jujube at Zhongning County
摘要
Abstract
Through the analysis of meteorological data and yield of red jujube in the experimental station in Zhongn-ing County of Ningxia ,combined with the records of main agro-meteorological disasters ,it was discovered that there were mainly 5 kinds of agro-meteorological disasters affecting the productivity of red jujube ,i .e .,high temperature in sprout-ing and leaf expansion stage (B1 ) ,high temperature and low humidity in florescence stage (B2 ) ,continuous rain in flo-rescence stage (B3 ) ,continuous rain in fruit growing stage (B4 ) ,and continuous rain in maturity stage (B5 ) .The ana-lytic hierarchy process (AHP) was adopted for quantitative analysis of these disasters ,which indicated that the influenc-ing weight of different disasters to the production of red jujube was sequenced as B 5>B4>B2>B3>B1 .The trend yields were corrected so as to forecast the actual output of red jujube in different stages ,and to set up the models of dynamic forecast of productivity ,which could be used as references in actual forecasting activities .关键词
