稀土元素镧、铈对擎天树幼苗生长量的影响
|
摘要
为探究稀土元素对擎天树林木生长量的影响,配置不同质量浓度的镧、铈元素溶液处理擎天树幼苗,观测镧、铈对其苗高、地径等生长量的影响。结果表明,铈质量浓度32 mg/L处理下苗木生长最佳,其苗高、地径的总增长量与月平均生长量以及总干质量较对照组增高了144.6%、46.9%、585.7%、60.0%、578.9%,均显著提高;望天树苗木在镧质量浓度64 mg/L处理下生长最好,但效果远不及铈;稀土元素铈对擎天树苗木苗高、地径、生物量的促进作用显著,可用于擎天树壮苗培育;2种稀土元素在较高质量浓度下对苗木的生长促进作用均降低。
To explore the impact of rare earth elements on the growth of forest,seedling of Parashorea chinensis were treated by different concentrations of lanthanum and cerium solution. The effect of La,Ce on seedling height,diameter and biomass were studied. The results showed that the growth of seedlings was the best under the treatment of 32 mg/L Ce. Compared with the CK,the total increment and the monthly growth of seedling height,the total increment and the monthly growth of ground diameter and the total dry weight were significantly increased by 144. 6%,46. 9%,585. 7%,60. 0%,578. 9% respectively. The best growth was under the treatment of 64 mg/L La,but the effect was far less than the Ce. The effects of rare earth element Ce on the seedling height,ground diameter and biomass were significant and could be used to cultivate the seedlings of the P. chinensis. The effects of 2 kinds of rare earth elements on the growth promotion of seedlings were lower under higher concentration.
