摘 要:
采用4种质量浓度稀土溶液、2种浸种时间处理长白落叶松种子并播种育苗，结果显示：不同质量浓度的稀土溶液和不同的浸种时间对长白落叶松1a生播种苗的苗高生长量、地径生长量、主根生长量、侧根数量、成苗率均有显著促进作用，以50mg·L^-1的质量浓度浸种处理4h的效果最好；使用该质量浓度处理后，苗高生长量较对照高出7．7％，地径生长量较对照高出24．1％，主根生长量较对照高出9．5％，侧根数量较对照高出43．0％，成苗率较对照高出28％。[著者文摘]

Abstract:
Raising seedlings test by sowing was conducted by immersing seed of lanthanon solution with 4 different concentrations and 2 immersed time, the results showed that： To the seedlings of 1 - yr - old of Ear＆ olgensis by , its growth in height and basal diameter, length of main root and amount of lateral roots, also in survival rate, can be greatly promoted by all treatment. The best result was from 50 mg· L^- 1 of lanthanon and immersed 4 hours; For mean height, basal diameter, main root length, amount of lateral roots and survival rate of the seedlings were increased by 7.7 %, 24.1%, 9.5%, 43.0% and 28.0%, respectively, compared to that of the control seedlings.[著者文摘]
