西伯利亚红松引种试验中的育苗研究

本研究为西伯利亚红松引种试验的子课题，是在满归林区，以带岭红松为对照进行的不同种源西伯利亚红松引种育苗试验。经几年研究，初步掌握了该树种苗期的生长规律，培育出达到前苏联及黑龙江省有关苗木分级标准要求的合格苗，且多数种源的西伯利亚红松生长好于对照，为该树种引种奠定了基础。

STUDY OF INTRODUCTION TESTOF PINUS SIBIRICA ON SEEDING

This article is the part of program that is introductiontest of Pinus sibirica.It is introduction and seeding test of different provenance of Pinus sibirica in contrast with Pinus koraiensis in Mangui\+s forest district.In recent years\+ study,We already knew elementarily growth rhythm of Pinus sibirica in seeding stage and bred successfully standard seedling that reached seeding sorting standard of the pre-Soviet Union and Heilongjiang Province.And the most of different provenance of Pinus sibirica grow better than control group,which lay a foundation for introduction test of Pinus sibirica.
