The results showed that rare earth elements could increase chlorophyll content, enhance photosynthesis, promote root system development and increase nutrient uptake by roots. Rare earth can also promote seed germination, improve seed germination rate and promote seedling growth. Besides above main action, still have the ability that makes certain crop strengthens disease resistance, cold resistance, drought resistance.
Rare Earth, is the chemical periodic table lanthanide elements and scandium, yttrium a total of 17 metal elements. There are 250 kinds of rare earth minerals in nature. The first rare earth was discovered by a Finnish chemist, John Gadolin. The first rare earth "element" (yttrium earth, or Y2O3) was isolated from a heavy bituminous ore in 1794. Because few rare earth minerals were discovered in the 18th century, only a small amount of water-insoluble oxides could be made by chemical processes. Rare earth is known as the "vitamin" in resources. Among the 35 strategic elements identified by the United States and 26 high-tech elements selected by Japan, all rare earth elements are included, which shows the precicity of rare earth. Do you know what the world would be like without rare earths?
According to the electron layer structure and physical and chemical properties of rare earth elements, as well as their co-occurrence in minerals and the characteristics of different properties of different ion radius can be produced.
A common analogy is that if oil is the blood of industry, then rare earths are the vitamins of industry.
Rare earth is the abbreviation of a group of metals, including 17 elements in the periodic table of chemical elements, such as lanthanum, cerium, praseodymium, etc., which have been widely used in electronics, petrochemical, metallurgy and other fields. Scientists discover new USES for rare earths almost every three to five years, and one in six inventions relies on them.
China is rich in rare earth minerals, ranking first in the world in terms of reserves, production scale and export volume. At the same time, China is the only country able to supply all 17 rare earth metals, especially the medium-heavy rare earth metals that are highly used for military purposes, with an enviable share. Comrade deng xiaoping once said: "the Middle East has oil, China has rare earth." The implication of his words is self-evident.
Rare earth, as a valuable strategic resource, is known as "industrial monosodium glutamate" and "mother of new materials" and is widely used in the fields of cutting-edge science and technology and military industry. According to the ministry of industry and information technology, the rare earth permanent magnet, luminous, hydrogen storage, the function such as catalytic materials are advanced equipment manufacturing, new energy, new industries such as new and high technology industries indispensable raw materials, is widely used in electronics, petrochemical, metallurgy, machinery, new energy, light industry, environmental protection, agriculture, etc.

The results show that rare earth elements can increase the chlorophyll content of plants, enhance photosynthesis, promote root development, and increase nutrient uptake by roots. Rare earth can also promote seed germination, increase seed germination rate and promote seedling growth. In addition to the above main functions, it also has the ability to enhance disease resistance, cold resistance and drought resistance in certain crops.
Rare Earth is a general term for 17 elements of lanthanides and lanthanum and cerium in the chemical periodic table. There are 250 rare earth minerals in nature. The first to discover rare earths was the Finnish chemist John Gadolin. In 1794, the first rare earth "element" (alumina, Y2O3) was separated from a bituminous ore-like ore. Because rare earth minerals were found in the 18th century, only a small amount of water-insoluble water could be produced by chemical methods. Oxide, historically used to call this oxide "earth", hence the name rare earth. Rare earths are called "vitamins" in resources. The 35 strategic elements recognized by the United States and the 26 high-tech elements selected by Japan include all rare earth elements, which is a rare trace of rare earths. If there is no rare earth, do you know what the world will be like?
According to the electronic layer structure and physicochemical properties of rare earth elements, and their symbiosis in minerals and different ionic radii, different properties can be produced.
A common analogy is that if oil is the blood of industry, then rare earth is the vitamin of industry.
Rare earth is an abbreviation of a group of metals, including 17 kinds of elements such as lanthanum, cerium and lanthanum in the periodic table of chemical elements. It has been widely used in many fields such as electronics, petrochemicals and metallurgy. Almost every 3-5 years, scientists can discover new uses for rare earths, and one out of every six inventions is inseparable from rare earths.
China's rare earth mineral deposits are rich in three world firsts: reserves first, production scale first, export volume first. At the same time, China is still the only country that can provide all 17 kinds of rare earth metals, especially the medium and heavy rare earths with outstanding military use. The share of China is enviable. Comrade Deng Xiaoping once said: "There is oil in the Middle East and rare earth in China." The tone of the words is self-evident.
Rare earth is a valuable strategic resource. It is known as “industrial MSG” and “mother of new materials” and is widely used in cutting-edge technology and military fields. According to the Ministry of Industry and Information Technology, functional materials such as rare earth permanent magnets, luminescence, hydrogen storage, and catalysis are indispensable raw materials for high-tech industries such as advanced equipment manufacturing, new energy, and emerging industries. They are also widely used in electronics and petroleum. Chemical, metallurgy, machinery, new energy, light industry, environmental protection, agriculture, etc.
研究结果表明，稀土元素可以提高植物的叶绿素含量，增强光合作用，促进根系发育，增加根系对养分吸收。稀土还能促进种子萌发，提高种子发芽率，促进幼苗生长。除了以上主要作用外，还具有使某些作物增强抗病、抗寒、抗旱的能力。
稀土(Rare Earth),是化学周期表中镧系元素和钪、钇共十七种金属元素的总称。自然界中有250 种稀土矿。最早发现稀土的是芬兰化学家加多林(John Gadolin)。于1794 年从一块形似沥青的重质矿石中分离出第一种稀土“元素”(钇土，即Y2O3),因为18 世纪发现的稀土矿物较少，当时只能用化学法制得少量不溶于水的氧化物，历史上习惯地把这种氧化物称为“土”，因而得名稀土。稀土被称为资源中的“维生素”， 美国认定的35个战略元素和日本选定的26个高技术元素中，都包括了全部稀土元素，足见稀土的珍贵。若没有稀土，你知道世界会如何吗？
根据稀土元素原子电子层结构和物理化学性质，以及它们在矿物中共生情况和不同的离子半径可产生不同性质的特征。
一个常用的比喻是，如果说石油是工业的血液，那稀土就是工业的维生素。
稀土是一组金属的简称，包含化学元素周期表中镧、铈、镨等17种元素，目前已被广泛应用于电子、石化、冶金等众多领域。几乎每隔3-5年，科学家们就能够发现稀土的新用途，每六项发明中，就有一项离不开稀土。
中国稀土矿藏丰富，雄踞着三个世界第一：储量第一，生产规模第一，出口量第一。同时，中国还是唯一一个能够提供全部17种稀土金属的国家，特别是军事用途极其突出的中重稀土，中国占有的份额让人艳羡。邓小平同志曾说：“中东有石油，中国有稀土。”其话语的弦外之音不言而喻。
稀土是宝贵的战略资源，有“工业味精”“新材料之母”之称，广泛应用于尖端科技领域和军工领域。据工业和信息化部介绍，目前稀土永磁、发光、储氢、催化等功能材料已是先进装备制造业、新能源、新兴产业等高新技术产业不可缺少的原材料，还广泛应用于电子、石油化工、治金、机械、新能源、轻工、环境保护、农业等.
