“稀土”(REM)是化学元素周期表中的镧系元素和钪、钇的统称。它包括镧、铈、镨、钕、钪等十七种性质相似的微量元素。除直接被植物吸收利用外,还能促进植物根系对氮、磷、钾和其它微量元素的吸收、运转和分配,增加植物体内叶绿素的含量,提高光合作用强度和光合产物的运转与积累,从而提高作物产量与品质。为了探讨稀土微肥对茶树生长发育和产量的影响,为茶叶生产上大面积推广稀土微肥提供可靠依 “Rare Earth” (REM) is a generic term for the lanthanides and scandium, yttrium in the periodic table of the chemical elements. It includes seventeen similar trace elements such as lanthanum, cerium, praseodymium, neodymium and scandium. In addition to direct plant absorption and utilization, but also to promote plant roots on nitrogen, phosphorus, potassium and other trace elements in the absorption, operation and distribution, increase plant chlorophyll content, improve photosynthesis intensity and photosynthetic production and operation, and thus Improve crop yield and quality. In order to investigate the effect of rare earth micronutrient fertilizer on the growth and yield of tea tree and provide a reliable basis for popularizing rare earth micronutrient fertilizer on tea production
