摘要
以引种在长春市的蒙古沙冬青为研究对象,进行了育苗基质选择、生长及越冬状况观测。结果表明:与紧实的黑土等基质相比较,以腐殖土:黑土:河沙=1:1:2的基质效果最佳,出苗率为70.1%;生长性状与原产地无明显差异,每年的高生长量为15 cm左右;在无防寒措施的露地环境中可安全越冬,无明显冻害发生。
Seedling substrate, growth and live situation through winter of Ammopiptanthus mongolicus were studled which had been planted in Changchun. The results showed that the survival rate was 70. 1% when seedlings were planted in soil substrate mixed with sands and humus at 1 ： 1 ： 2, higher than those planted in original soil. The growth ofA. mongolicus in Changchun was similar to those in original region, keeping about 15 cm height growth each year. A. mongolicus could live thought winter safely on open field without winter protection, indicating A. mongolicus could adapt to the local climate conditions, and is suitable for introduction and cultivation in Changchun.
