不同栽培措施对新疆灰枣一年生枣头枝抗寒力的影响
Effects of Different Cultivation on Annual Branch Cold Resistance of Xinjiang Huizao jujube (Zizyphus jujuba Mill.)
摘要
Abstract
[Objective] Effects of different cultivation on annual branch cold resistance of Xinjiang Huizao jujube (Zizyphus jujuba Mill. ) were evaluated to select basic parameters for making appropriate cultivation method. [ Method ] 23 cultivation treatments including controls of irrigation and additional fertilizing in late stages, controls of winter irrigation, controls of fruit loading and control of retarded growing retarded were set on 4 years Xinjiang Huizao jujube. 5 indexes including relative conductance, proline value, soluble total sugar value and bond water/free water ratio of annual branches stressed under -27℃ were measured to evaluate the effects on cold resistance. [Result]Proper growing retarded control increases bond water/free water ratio and soluble total sugar value of annual branch. Irrigation in late stages takes effects on proline value and bond water/free water ratio of annual branches. Proper winter irrigation increases bond water/free water ratio significantly, and effects soluble total sugar value and proline value certainly. Additional fertilizing in late stages effects branch bond water/free water ratio Fruit loading effects branch soluble total sugar value. [Conclusion]Single cultivation method including Paclobutrazol (PP333) 8g per tree, twice irrigations at the beginning of August and mid — September, phosphorus potassium fertilizing once at the end of September, 75%fuirt loading, winter irrigation in early November will increase annual branch cold resistance of Xinjiang Huizao jujube varying.关键词
