枣树抗旱机制的探讨

Probe on the Drought resistance Mechanismof zizyphus jujuba

通过观测研究枣树的生长习性、形态结构及生理指标 ,从多个方面研究了枣树的抗旱性。研究发现 ,枣树是一种强抗旱经济树种 ,其抗旱性包括了避旱性、御旱性和耐旱性三个方面 ,是生长习性、形态结构及生理等方面综合作用的结果。同时发现 ,其抗旱以降低生产力为代价 。

The drought resistance of Zizyphus jujuba have been analysesed from several aspects such as grow characteristics, morphology anatomy structure and physiology indexes. The results of study indicated; Zizyphus jujuba is strong resitant to drought, Its drought resistance includes drought avoidance, drought defence and drought tolerance,is the results acted comprehensively by the grow characteristics, morphology anatomy structure and physiology. Meanwhile, as the drought resistance of it make benefitiable effects at the lost of reducing production forces,the management of water and fertilizer should be strenghened in necessary period.
