摘　　要：水分对苗木移栽成活率有重要的影响,为研究其对枣苗移栽的影响,以一年生灰枣嫁接苗为材料,通过不同的晾晒处理进行了移植栽培,结果表明晾晒使苗木失水,失水导致苗木成活率降低,苗木体内的含水量随着晾晒时间的延长而减少,晾晒时间不宜超过1.5d,如果超过,苗木就会大量死亡,其成活率也大为降低。Water content has important influence on survival rate when transplant seedlings. The author object to study the effects of different drying treatment on Jujube transplanting seedlings survival rate. Different drying in the air treatment on one-year-old Jujube grafting seedlings were carried out. The results indicated that drying in the air causes the seedlings dehydrate, accordingly reduce the survival rate. Water content of seedling decreased along with the drying time in the air. A drying time not surpass 1.5 days when transplanting is proposed, otherwise, the transplanted seedlings would die massively hence the survival rate reduces greatly.
