采用随机区组设计了青剌果不同播种时间和不同播种方法试验,进行青刺果不同育苗方式对比研究。结果表明:青刺果的育苗宜随采随播,其种子出苗率达72.4%,随着种子储藏时间的后移,出苗率显著下降,干藏与沙藏对种子出苗率的影响差异不明显;裸根苗和容器苗苗木生长质量上无明显差别,随采随播到当年雨季造林时(9月)苗木嫩小,不宜上山造林,但容器苗此时可造林。
The sowing time and sowing method of Prinsepia utilis Royle were invettigated in randomized block design. The result showed that seed should be immediately broadcasted after colletion, the seed germination rate reached 72.4%, along with sowing date postponded, the seed germination rate decreased significantly. However, the seed germination rate was no significantly differences between the dry and sand storage. The bare - rooted and container seedlings were no significantly differences between the seedling growth and seedling quality, during the rainy season that year (in September) , seedlings was little and tender and should not go into the mountains for afforestation, but container seedlings can be planted at this time.
