根据沙雅县近几年来在红枣栽培和管理工作中总结的经验,新植枣树在覆膜套袋后成活率可提高12%以上。沙雅县由于春季气温回升快,土温回升慢,气温高于土温;枣树根系20~25℃时生长旺盛,土温降至21℃时生长减缓,至20℃以下则停止生长。移植的枣苗只有在根系20~25℃时生长旺盛时长出新根。枣苗起苗后根系大部被切断,
According to the experience of Shaya County in jujube cultivation and management in recent years, the survival rate of newly-planted jujube trees can be increased by over 12% after being bagged by membrane. In Shaya County, the soil temperature rose slowly and the temperature was higher than the soil temperature due to the rapid warming in spring. The jujube roots grew vigorously at 20-25 ℃, the growth slowed down when soil temperature dropped to 21 ℃, and stopped below 20 ℃. Transplanted jujube seedlings grow only in the root 20 ~ 25 ℃ when the growth of new roots. Jujube seedlings most of the roots were cut off,
