朝阳地区鲜食枣冷棚栽培效果初报

Preliminary Report on Cultivation Effect of Fresh Jujube in Cold Shed in Chaoyang Area

朝阳地区枣露地栽培9月中下旬成熟,个别年份此间降雨量较大,裂果率达50%~80%。为解决集中上市、裂果等问题,采用冷棚栽培,兼具避雨功效,通过精细化管理,枣果可比露地提前20 d左右成熟,供应期8月中旬至9月下旬,裂果率小于5%。该研究可为冷棚覆盖保温材料栽培枣模式的进一步提早成熟、避雨栽培提供参考。

Open field cultivation of jujube in Chaoyang area was mature in mid-to-late September.In some years,when the rainfall was high in this period,and the fruit cracking rate would reach 50%-80%.In order to solve the problems of centralized market and fruit cracking,the author and team adopted cold shed cultivation,which was heated up in late February.Through fine management,the jujube fruits matured about 20 days earlier than the open field,and the supply period was from mid-August to late September.The fruit cracking rate was less than 5%.This study could provide a reference for further early maturity and rain shelter cultivation of jujube in cold shed covered with heat preservation material.
