长白落叶松苗最佳密度的小气候研究（Ⅲ）──长白落叶松苗群体不同密度生物生长量的研究

Study on the Microclimmte of Larix olgensis Seedling under Optimum Density(Ⅲ)──The Biomass Increment of Larch Seedlings in Different Densities

本文分析了长白落叶松苗期不同密度的生物生长量的数据，得出长白落叶松苗最佳密度为６００～７００株／ｍ￣２，并提出了提高长白落叶松苗期速生丰产的措施．

Through analyses on biomass increment data of Larix olgenisis seedlingsin different density conditions,the optimum density range was obtained,from 600 to 700individuals per square metre,and the measures of fast-growing and high-yeilding of Lar-ix olgensis seedlings were proposed.
