肥料和密度对玉米籽粒蛋白质及醇容蛋白含量的影响

Effect of fertilizer and density on protein and zein content of maize kernels

研究了肥料和密度对玉米籽粒蛋白质及醇容量的含量的影响。结果表明,氮、磷、钾和密度等单项措施对玉米籽粒蛋白质含量的影响呈二次曲线。4种因素之间存在明显互作效应,采取适宜的氮、磷、钾比例与合理的种植密度可以提高玉米籽粒蛋白质含量。氮肥和密度的影响较大,随氮肥的增加醇溶蛋白含量迅速增长,接近+0.69水平时达到最高,而后略有降低。

The effect of N,P,K or plant density on protein content of kernel all can be expressed by conic,and there is mutual effect between the four factors. Therefore,the protein content can be increased by regulating fertilizer and plant density. The zein content increase rapidly with the increasing of nitrogen,and get the top when the nitrogen is closely +0.69 level.
