Abstract: According to statistics, the most serious meteorological disasters of Zhanhua winter jujube producing areas is precipitation anomaly disaster, including rainstorm, flood, drought, so precipitation conditions become meteorological factors which caused adverse effect the most easily in the winter jujube producing areas. In order to understand the precipitation adaptability of Zhanhua winter jujube, the precipitation anomaly disaster had been counted since winter jujube brought about industrialization, combined with the observed data of precipitation in Zhanhua national meteorological station only. The Zhanhua winter jujube suitable precipitation characteristics was summarized, combined with the precipitation anomalies in precipitation disaster time, precipitation conditions adverse to the Zhanhua winter jujube were analyzed further. Causing disaster of precipitation conditions was estimated.
