稀土元素镧、铈对擎天树幼苗生长量的影响
Effects of Rare Earth Elements La and Ce on Growth of parashorea chinensis Seedlings
摘要
Abstract
To explore the impact of rare earth elements on the growth of forest,seedling of parashorea chinen-sis 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 di-ameter 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.关键词
