七十年代以来,我们对水稻锌肥应用及其有效施用条件有过较多的研究,对水稻硅肥肥效也做过一些试验。国内外这类研究较多,但综合研究硅、锌、锰对水稻生长及元素吸收利用的影响,则报道较少。而植物体内各营养元素之间有一定平衡关系,常相互影响,由于营养离子间的相互作用,往往改变了单一营养元素的吸收水平。元素交互作用是一个十分复杂的过程,特别是多元素的交互作用,各国学者都在探索。Park等指出水稻土管理中保持多元素平衡是高产的关键技术之一。为此,1991～1993年我们开展了这方面的研究。
Since the seventies, we have made more studies on the application of zinc fertilizer and its effective application conditions, and have done some experiments on the efficiency of silicon fertilizer in rice. There are more studies at home and abroad, but the comprehensive study of the effects of silicon, zinc and manganese on rice growth and elemental absorption and utilization is less reported. The vegetative elements of the body have a certain balance between the various, often affect each other, due to the interaction between nutrients, often change the level of absorption of a single nutrient. Element interaction is a very complex process, especially the interaction of multiple elements, scholars from all over the world are exploring. Park et al. Pointed out that paddy soil management is one of the key technologies for maintaining high production balance. For this reason, we carried out the research in this area from 1991 to 1993.
