山西省高寒区枣树设施栽培技术研究初报

摘要

Taking experiments of sunlight greenhouse cultivation of jujube in colder area in Shanxi province, protected cultivation could reach or surpass open-air cultivation of suitable region in the city of Taiyuan and Jinzhong, and satisfy completely the re-quirements of the jujube tree growth to reach economic cultivation.Tent-buckling stage was between 15 to 30 January.Thermal control technology before July was the key technology.Compared with suitable area open-air cultivation, bud germinating period was in late March which was ahead of schedule for 20~30 days, and new shoots grew 10~15 days in advance, but the other phenological phases were closer to that of the suitable area.In 0.5 m ×1.0 m garden of 2 years old plant, the fresh jujube pro-duction reached 1 067.2 kg/667 m2 , and 1 m ×2 m garden reached 500.3 kg/667m2 , the economic benefit was significant.%在山西省高寒区进行日光温室大棚枣栽培试验,试验表明,设施栽培能够达到或略超适生区太原市、晋中市露天栽培的条件,完全可以满足枣树生长发育的要求,达到经济栽培的目的. 1月15日至30日为扣棚时间,7月以前的保温调控技术是关键技术. 与适生区露天栽培相比较,萌芽期为3月下旬,提前了20 d~30 d;新梢生长提前10 d~15 d,但其它物候期与实生区接近. 2年生时0.5 m ×1.0 m园内鲜枣产量达1 067.2 kg/667 m2;1 m ×2 m园内鲜枣产量达500.3 kg/667 m2 ,经济效益十分显著.
