日本落叶松(Layix leptoiepis siebet zucc cord),Larix Kacmopteri(lamb)-Sargent)在我国东北地区是个很有发展前途的树种。在当前大面积造林尚不能实行全面施肥和灌水措施的情况下,如何施用一般条件下的技术措施、达到营造速生丰产林的目的,显然是非常重要和迫切的。为探讨这一重要问题,我们根据过去的研究体会,总结以下几点,供生产部门参考。 Larix Kacmopteri (Lamb) -Sargent) is a promising species in northeastern China. Under the circumstances that large-scale afforestation is still unable to implement comprehensive fertilization and irrigation measures, it is obviously very important and urgent to implement the technical measures under normal conditions and achieve the objective of creating fast-growing and high-yield forests. To explore this important issue, we based on past research experience, summarize the following points for the production department for reference.
