| Abstract: |
| Through the analysis of meteorological data and yield of red jujube in the experimental station in Zhongning 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 sprouting and leaf expansion stage (B1), high temperature and low humidity in florescence stage (B2),
continuous rain in florescence stage (B3), continuous rain in fruit growing stage (B4), and continuous rain in maturity stage (B5). The analytic hierarch
y process (AHP) was adopted for quantitative analysis of these disasters, which indicated that the influencing weight of different disasters to the production of red jujube was sequenced as B5>B4>B2>B3>B1. The trend yields were co
rrected 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. |
