摘要
华北落叶松Ｌａｒｉｘｐｒｉｎｃｉｐｉｓ－ｒｕｐｐｒｅｃｔｉｉ苗期的生长规律说明，苗期内苗木各器官的蕴育、生长、发育都遵守着一定的时间规律。同时也表明根系是苗木的重要器官，特别是侧根根系的强弱和规模，对苗木的影响几乎是决定性的。因此，在育苗过程中一切促进苗木根系发育的措施，也都是提高苗木质量的措施。
The year growth law of Prince Rupprecht′s Larch (Larix principis-rupprechtii) illustiates that all seedling organs abide by the certain time law in its formation, growth and development. It also demonstrates the root is the important organ, especially the root size and density, which have determinate influence on seedlings. All measures promoty root developing in the course of seedling cultivation are thorefore those which can improve the quallty of seedlings.
