稀土元素是化学元素周期表中镧系元素:包括镧、铈、镨、钕……铥、镱、镥和性质相似的钪、钇共十七种化学元素的总称。它们不但性质相似,而且在矿物中共生。现在世界上越来越多的资料证实,植物不仅需要氮、磷、钾三种元素,而且还需要一定的微量元素肥料来满足其生长发育的需要。稀土元素正是具有这种效用,故可作为微肥使用,它可以使多种作物增产增收。使用方法可浸种、拌种和叶面喷施。 为了探讨稀土元素对蔬菜的作用,我们引进了稀土元素处理辣椒种子发芽试验。
Rare earth elements of the periodic table of the chemical elements of lanthanides: including lanthanum, cerium, praseodymium, neodymium ... ... 铥, ytterbium, 镥 and similar properties of scandium, yttrium total of 17 kinds of chemical elements. They are not only similar in nature, but also symbiotic in minerals. Now more and more data in the world confirm that plants not only need nitrogen, phosphorus and potassium three elements, but also require a certain amount of trace element fertilizer to meet the needs of its growth and development. Rare earth elements have this effect, it can be used as a fertilizer, it can increase a variety of crop yield. How to use it Soaking seed, seed dressing and foliar spray. In order to explore the effect of rare earth elements on vegetables, we introduced the rare earth element treatment of pepper seed germination test.
