摘要
文中探讨了茎部施用稀土元素对金桔的生长和生理基础的影响，通过茎部施用不同浓度的稀土元素来考察金桔叶相对生长率、新梢相对生长率、叶绿素含量．结果表明茎部施肥对植株的生长有明显地促进作用，且茎部施用稀土浓度不同对金桔的生长影响也不同，而且茎部施用稀土元素效果优于根部施用稀土元素．
The effects of trunk injection of REE on the growth and physiological factors of kumquat are studied. The effects of relative growth rate of leaves and tips, chlorophyll content, etc. are observed by using REE with different concentrations. Results show that truck injection fertilizer has apparent promoting effect on plants growth, and the effects on the growth of kumquat vary with the concentration of injection REE, and the effects of trunk injection REE are superior to those of root applying REE.
