摘要
应用"3414"试验设计方案对贵州省天柱县城附近的早熟白菜生产进行了肥料效应试验,通过对试验数据的经济效益分析和三元二次回归分析表明,采用氮、磷、钾比例为1∶0.446∶0.392配方,能够获得较理想的经济和社会效益。
The fertilizer effect experiments were conducted to early Chinese cabbage nearby Tianzhu County of Guizhou City by ＂3414＂ method.Then,the economic benefit analysis and ternary quadratic regression analysis were conducted to experimental datum,and the results showed that when proportion of nitrogen,phosphorus and kalium in fertilizer was 1∶ 0.446∶0.392,the economic benefit and social benefit were the best.
