金叶莸种苗设施贮藏技术研究初报

Facility Storage Technique of Caryopteris clandonensis 'Worcester Gold'

研究了温度和湿度、5种根系处理、不同贮藏时间对金叶莸失水率、成活率的影响。结果表明，在不同介质时，成活率随着贮藏时间的增加而略呈下降趋势，失水率随着贮藏时间的增加而略呈上升趋势。冬季在冷库湿度90％～95％；温度0℃～3℃条件下，贮藏60d不同根系处理的苗木成活率达98％以上、失水率10．9％内；春季蘸泥浆处理的苗木贮藏60d成活率达85％以上。

The dehydration rate and survival rate of Caryopteris clandonensis＇Worcester Gold＂ were studied under the conditions of 2 kinds of temperature and humidity, 5 treatments to root system, and different preserving time. The results indicated that under different media, the survival rate declined with the increase of preserve time, and the dehydration rate increased slightly. The survival rate of nursery stock reached over 98% with the dehydration rate within 10. 9% under the storage humidity of 90%-95%, the temperature of 0℃-3℃ and preserving time of 60 days in the winter. The survival rate reached over 85% after the nursery stocks were dipped with mud and preserved 60 days in spring.
