摘要: 应用“3414”回归最优设计原理在赤峰市翁牛特旗大兴农场设置玉米肥效试验,拟探讨不同施肥处理对玉米产量的影响。结果表明:所有处理中处理6氮磷钾都处于2水平时产量最高达1145kg/667m^2。处理1不施肥时产量最低547kg/667m^2,两者相差达显著水平;分别对比不同氮肥、磷肥、钾肥用量下的玉米产量发现在其它两种肥料不变的前提下单一提高另一种肥料的施用量,玉米的产量随着肥料用量的提高出现先提高后下降的情况;对比各缺素处理发现不施氮肥对玉米的产量影响较大,明显低于不施磷、钾肥处理,说明氮肥对玉米的产量影响大于磷、钾,对比缺磷缺钾处理,对玉米的产量影响相差不大,说明玉米产量对磷、钾的依赖情况相似。

Abstract: Application of "3414" design theory in Daxing farm of Wengniute of Chifeng City to set corn farm effieiency test,to investigate the effect of different fertilizer treatments on corn yield.The results showed that: The yield of treatment 6 was the highest reaching 1145kg,when no fertilizer deal with a minimum yield of 547 kg,the difference was significant; were compared with different dosage of nitrogen, phosphorus and potassium found that while the other two fertilizers keep unchanged only increased a single use of another fertilizer, maize yields increased with the fertilizer at first and then decreased when continued to improve the amount of the fertilizer; Contrast the treatment of founded that the treatment without nitrogen has notable effect on corn yield; much lower than that applied P and K treatment, indicating nitrogen fertilizer on corn yield is greater than P and K;Contrast with no potassium and no phosphorus treatment, The deficiency of corn yield was not significant, which indicated corn yields similar to the dependence of the phosphorus and potassium.
