摘要
利用国家科学技术成果,并根据国内外研究现状,将个化学元素分成对作物生长103发育、增产起显著作用、起一定作用、起有害作用和起未知作用个农业生态元素类型,进而论4述了它们与作物优质高产的关系。
103 elements were divided into 4 sorts of element of agriculture ecology by using national fruit of science and technology, according to research status quo inside and outside home. First sort was distinct in promoting the development and increasing production of crop, the second had some positive effect, the third harmful influence, and the fourth unknown effect. The relation between elements and high grade-yield crop was discussed.
