天津市大港地区枣粮间作丰产栽培技术

Jujube and Grain Intercrop Cultivation Technology in Dagang Region of Tianjin

通过研究、分析，总结出大港地区枣粮间作模式和丰产栽培的技术要点。丰产栽培技术包括枣粮的肥水管理、保花保果技术、合理修剪和病虫害防治方法等。栽培模式可分为以枣为主、以粮为辅的间作模式；以粮为主、以枣为辅的间作模式；粮枣兼顾的模式。３种间作模式枣树栽植密度不同，但枣树定干高度应在１～１．４ｍ，树高度应控制在５～６ｍ为宜。

Through study and analysis,the model of cultivation technology of jujube and grain intercrop at Dagang region is summerized as follows:the technology of fertilization and water management of jujube and grain,the protection of flower and fruit,rational pruning,and the method of disease and pest control.It may take the jujube cultivation model in the first place and the grain in the second place,at the same time,the model of this intercrop should take care of both jujube and grain.The three kinds of intercrop model is different,the density of jujube planting is different,the height of jujube tree should he controled at 5～6 m.
