施肥对玉米品质的影响研究

以高淀粉玉米品种华单208和普通玉米品种农大364为供试材料,采用正交试验设计,分析氮、磷、钾对2种不同类型玉米的产量性状及品质性状的影响。试验结果表明:磷、钾对玉米品种营养品质的影响大于氮。施磷后,高淀粉玉米华单208的脂肪含量增加了7.14%;施钾后高淀粉玉米华单208的蛋白质含量增加了4.82%,农大364品种的蛋白质则增加了3.72%。

Study on the Effect of Fertilization on the Quality of Maize

Taking the high starch maize variety Huadan 208 and normal maize variety Nongda 364 as tested material,the effects of nitrogen,phosphorus,potassium on two different types of maize yield and quality characters were analyzed by orthogonal experiment design. The results showed that,the effect of phosphorus,potassium on nutritional quality of maize varieties was higher than that of nitrogen,the fat content of high starch maize Huadan 208 increased by 7.14% after the application of phosphorus,protein content of high starch maize Huadan 208 increased by 4.82% and protein of Nongda 364 varieties increased by 3.72% after the application of potassium.
