农业上应用稀土已取得显著效益。为准确地肯定稀土对林业苗木的增产效用,并摸索关键技术,1987年至1989年,在温室和田间进行泡桐实生苗水培和埋根苗应用试验。水培试验部分地采用了植物稳态营养研究的理论和方法。
Agricultural application of rare earth has made significant benefits. In order to accurately confirm the effect of rare earth on the yield increase of forestry seedlings, and to explore key technologies, from 1987 to 1989, in the greenhouse and field Paulownia seedlings hydroponic culture and burying root application test. Hydroponic experiments partially adopted the theory and method of plant steady-state nutrition research.
