稀土主要由镧、铈、镨、钕等15种镧系元素和钪、钇共17种元素组成。目前,生产中使用的稀土肥料主要是硝酸稀土,商品名称为稀士“农乐”或益植素,其氧化物含量为38％。随着稀土农用技术的应用与推广,稀土林用技术也有了一定的发展,但有关稀土林用方面的报导甚少,为了使更多的林业生产者了解和利用这项投资少、使用方便、收益大的新技术,本文就稀土林用技术方法做介绍,供使用中参考。
The rare earth mainly consists of lanthanum, cerium, praseodymium, neodymium 15 kinds of lanthanides and scandium, yttrium a total of 17 kinds of elements. At present, the rare-earth fertilizers used in production are mainly rare earth nitrates, the trade name of which is “Nongle” or Yi-Zu, which has a content of 38% of oxides. With the application and popularization of rare earth agricultural technology, rare earth forest technology has also made some progress, but few reports on rare earth forest use. In order to make more forestry producers understand and utilize this investment with less expense and easy to use, Revenue of new technologies, this paper describes the technical methods of rare earth forest for reference.
