摘要
采用四因素三水平的正交试验设计方法,对杂交玉米奥玉005在安顺市西秀区的高产配套栽培技术模式进行研究。结果表明各因素对产量影响的效应大小排列为密度>施氮量>施磷量>施钾量,说明密度对奥玉005的影响较大;最佳组合为密度3300株/667m^2,施尿素40kg/667m^2,施磷肥50kg/667m^2。
4 factors with 3 levels by orthogonal design was applied on study of high yield cultivation techniques for Aoyu 005 in Xixiu, Anshun. The results showed that the factor influence yield was planting density 〉 nitrogen fertilizer 〉 phosphorus fertilizer 〉 potassium fertilizer, it＇ s indicated that planting density take great influence on yield of Aoyu 005, and the best, combination of planting density, urea, phosphorus fertilizer, potassium fertilizer is 3300plants/667m2, 40kg/667m2, 50kg/667m2, 20kg/667m2, respectively.
