摘要
选用对玉米产量有重要作用的氮和被称作为品质元素且与氮有明显交互作用的钾, 以及在北方地区植物和人体共同缺乏的锌为肥源因子, 采用二次通用旋转回归组合设计的试验方法, 定量探讨了氮、钾、锌肥配施对玉米地上部分氮、钾、锌含量和分布的影响, 为北方地区玉米高产、优质提供合理施肥依据。
N,K which had interactive effect with N, and Zn which were low in the plant and human body in the North Part of China were chosen as experimental fertilizers. The effects of combined N and K and Zn fertilizers on the nutrition accumulation and contribution in corn shoot were studied with the experiment designed with the general rotative regression method in order to find out the best fertilizing technology for the high yield and high quality of corn in the North Part of China.
