内蒙古西部干寒地区保护地大枣引种栽培试验研究

THE RESEARCH OF THE BIG DATE INTRODUCTION CULTIVATION EXPERIMENTS IN GREENHOUSE IN WESTERN COLD AREA OF INNER MONGOLIA

内蒙古干寒地区保护地大枣引种栽培试验研究结果表明:保护地适宜栽培的优良鲜食大枣品种为梨枣、冬枣、马奶枣。同一大枣品种的果实含糖量、Vc含量远高于原产地,口感好,品质更佳。在保护地采用矮化、密植、早果、丰产、优质综合配套技术,提高幼树的座果率。枣树花期喷水、喷肥,提高和保持空气湿度,及时补充营养,可有效提高枣树开花坐果率,为丰产提供保障。

The research of the big date introduction cultivation experiments in greenhouse in western cold area of Inner Mongolia indicated as follows： the good and fresh species of the big dates were Li date,Winter date,Ma Nai date in greenhouse.The sugar content and the Vc content are far higher than those of the original area.The flavor feels good and the quality is better.Using synthesizes techniques of dwarfing,density plants,early fruit,plentiful production,the superior quality cultivation and so on,increasing the fruit setting rate of the young tree.Though sprays the water and fertilization during the blossom period,increase and maintain air humidity and complement nutrition on time,we could increase the fruit setting rate of date tree and offering the guarantees for good production.
