摘要: 运用三因素五水平二次正交旋转组合设计方法,研究了雅安地区蓉油3号栽植密度、氮化肥与磷化肥的用量对产量及主要经济性状的影响,并建立了相应的数学模型,得出在试验的土壤肥力水平下产量达2.25t/hm2以上的高产栽培技术方案是:栽植15-16.5株/m3,分别施化肥N100-150kg/hm2和P2O545-75kg/hm2

Abstract: A field experiment of quadratic orthogonal regressive rotation design of three factors was conducted. The mathematical models of planting density, application rate of nitrogen and phosphorus for high-yielding and other economic characters were established and the scheme of cultural practices for yielding above 2.25t/hm2 was computed from the model as fellows: transplanting at the densities of 15.5-16.5 plants/m2, applying the fertilizers N 100-150 kg/hm2 and P2O545-75kg/hm2.
