摘要
为了解决红松育苗周期长、造林成活率低等林业生产中存在的实际问题,于1992年开始进行红松塑料大棚工厂化容器育苗技术的研究。结果表明:用草炭土+腐殖土、腐殖土+马粪、草炭土+马粪配制的三种营养基质,最有利于红松幼苗的生长;培育红松容器苗不仅需要施用大量的N、P、K肥料,而且还需要补充Fe、Cu、Mo、B、Zn和维生素B1]等微量元素;塑料大棚可提高温、湿度,提前和延长了幼苗生长期,2年生即可出圃造林,缩短育苗期2年;红松容器苗根系发达,造林后不缓苗,成活率与保存率高,不需要补植。
The cultivation technique of Korean pine (Pinus koraiensis Sieb. et Zucc.) container seedlings in greenhouse was studied to resolve some practical problems in forestry production such as the long cultivating term and the low survival rate of Korean pine. It indicates that it is the best for the growth of seedlings to use three kinds of nutrient media: turfy soil+humus soil, humus soil+horse muck, turfy soil+horse muck. It is needed to fertilize not only plenty of N, P and K, but some minor elements such as Fe, Cu, Mo, B, Zn and Vitamin B1] to cultivate the container seedlings. Greenhouse can increase temperature, moisture and prolong the growth period of seedlings. Two-year-old seedlings can be used for plantation, and greenhouse can shorten the cultivating term two years. The roots of Korean pine container seedlings are so strong that they have no growth buffer, and they have high survival rate and preserving rate. It doesn't need additional supplement.
