大棚冬枣栽培技术

Greenhouse Techniques of Dongzao(Zizyphus jujuba Mill. cv. Dongzao) Cultivation

为了冬枣的优质早熟,减少成熟期的阴雨损失,我们研究了大棚冬枣栽培技术。通过棚体建造,选择2月上旬开始扣棚,5月底揭棚,并采用规范的棚内温度控制,可使冬枣提前成熟20~30 d,品质和优果率明显提高。在栽培管理上一次施足基肥,扣棚前灌水1次,其它措施类似于冬枣的大田管理。大棚冬枣栽培技术,解决了冬枣座果难的问题,水肥投入减少,虫害减少,但温度控制要求严格,否则会造成损失。大棚冬枣效益显著,减低了成熟期遇雨裂果的风险,优化了产业结构,值得我国同类枣区借鉴。

To make the winter date ripen earlier and have a good quality and reduce the loss caused by rain to minimum,greenhouse techniques of Dongzao（Zizyphus jujuba Mill.cv.Dongzao） cultivation were developed.To cover the greenhouse in early Feb.and open the cover at the end of May,together with proper temperature control,will have the dates ripened 20~30 days earlier.Cultivation of Dongzao Jujube in greenhouse solved the problems of fruit setting and reduced the pest and disease and the cost of irrigation and fertilization.Greenhouse techniques for Dongzao Jujube produced higher economic benefits and reduced the damaged caused by rainfall during the ripening period.
