摘要：

以四倍体酸枣生根组培苗为试材，研究炼苗天数、基质种类、空气相对湿度、组培苗高度、根条数及移栽时间对组培苗移栽成活率和生长的影响。结果表明：移栽应在4月底至6月进行，在此时期选择高度大于5 cm，根7条以上的组培苗，经炼苗3天，移栽至纯蛭石或珍珠岩与土（1:1）或蛭石与土（1:1）中，移栽前期保持空气相对湿度在90%以上，移栽成活率可达70%以上。

Abstract:

The survival rate and growth status of transplanting in vitro plantlets with roots of tetraploid Ziziphus acidojujuba were investigated under different conditions, including training days, medium, air relative humidity, plant height, root quantity and transplanting time. The results showed transplant should be carried out from the end of April to June. After 3 days training cultivation, plantlets with 7 or more roots and the height of over 5 cm were transplanted in vermiculite, perlite and soil (1:1) or vermiculite and soil (1:1). The air relative humidity was kept over 90% during the early stage of transplanting. The survival rate would be more than 70%.
