Abstract:
Rare earth micro-element fertilizer is a kind of agricultural rare earth compounds , which plays an important role in improving crop yield and quality , promoting agricultural harvest , alleviating the contradiction between population growth and the lack of cultivated land , promoting sustainable development of domestic agriculture and realizing“less application with better efficiency”. This paper reviews studies of recent years on the effects of rare earth micro-element fertilizer on crop ripening , yield increase and disease resistance , and introduces the regulating effects of such fertilizer on crop physiology and biochemistry. It is eXpected that with the continuous development of rare earth micro-element fertilizer theory in the future , the popularization and application of such fertilizer will be further developed and its categories will become more and more abundant.
