稀土元素是化学元素周期表ⅢB族中的钪、钇与15个镧系元素的总称。我国稀土资源丰富,拥有能够生产各种稀土产品的工业体系,自1972年以来,开展了稀土农用的研究。通过在稻、棉、瓜果和蔬菜等作物上的应用,证明稀土化合物具有增强农作物抗病能力、改善农产品品质和提高产量的作用,施用之后,对环境和农产品无污染,对人畜安全且无副作用。 虽然已有在花生生产中施用稀土的报道;但尚无在根瘤菌剂中添加稀土的先例。我们率先将稀土化合物引入到根瘤菌剂中,研制出了接种剂的新剂型—稀土根瘤菌剂。本文报道稀土菌剂的研制与应用效果。
The rare earth elements are the general term for scandium, yttrium and 15 lanthanides in group ⅢB of the periodic table. China is rich in rare earth resources and has an industrial system capable of producing all kinds of rare earth products. Since 1972, research on rare earth agriculture has been carried out. The application of rare earth compounds on crops such as rice, cotton, fruits and vegetables proves that the rare earth compounds have the function of enhancing the disease resistance of crops, improving the quality of agricultural products and increasing the yield. After being applied, the rare earth compounds have no pollution to the environment and agricultural products, side effect. Although there have been reports of the application of rare earths in peanut production, there is no precedent for adding rare earths to rhizobia. We took the lead in the introduction of rare earth compounds into rhizobium agents, developed a new form of inoculant - rare earth rhizobium agents. This article reports the development and application of rare earth fungi agents.
