摘要
采用大田与盆栽相结合的方法,研究了不同形成微肥对玉米的增产作用。结果表明,氨基酸螯合多元微肥可延长玉米根系和叶片的功能期,提高玉米植株的干物重,使玉米产量提高12.9%~14.3%。其作用不仅优于微量元素和稀土,又优于氨基酸与微量元素形成的螯合微肥。
With combination of field and pot-culture method a study was carried out on the in-creasing effects of different morphology of micro-element fertilizers on maize.The results indi-cated that chelate compound of ammino acid with microelement fertilizers which consists ofammino acid,micro-element and rare earth could prolong the functioning duration of maizeroots and leaves and increase the plant dry weight and maize yield by 12.9%~14.3%.The ef-fects of it were better not only than that of single application of micro-elements or rare earth,but also were better than that of chelate micro-elements of ammino acid with micro- elements.
