Abstract:
In order to make full use of climate resources, pursue better benefits while avoiding disadvantages, plan and develop the apple industry in Shaanxi reasonably, and promote the optimization of apple planting layout and the healthful and sustainable production at county level, the apple drought indexes at each growth stages for 4 apple planting counties, which are on behalf of the different climate types, are calculated and analyzed, in combination with the actual geographical and climate features of apple growing areas in Shaanxi Province. The apple drought risk regionalization is conducted for each growth stage and 4 apple planting counties. The results show that the period from apple budding to young fruit appearing is the time in which apple trees are most likely attacked by droughts in Shaanxi in the whole growth period, and the fruit enlargement period is the second, then the period from coloring to mature and the wintering period; in the whole growth period, apple drought in Yan’an is the most serious, then in the northeastern and northwestern Weihe, and apple drought in Guanzhong is the least serious relatively. The results can be used as references for anti drought service at different apple growth stages in different apple growing areas in Shaanxi and for decision making in disaster prevention and mitigation of apple industry.
