Abstract:

An orthogonal quadratic regression rotation combinatorial design with 4 factors, row spacing (X1), nitrogen (X2), phosphor (X3) and potassium (X4), was adopted in field experiments. Regression models were created and analyzed for 1000-grain weight and seed yield per ha, respectively. The results show that the effects of four factors on 1000-grain weight are ordered as X2 >X4 >X3 >X1 and on seed yield per ha are X1 >X2 >X3 >X4. Based on the regression models of 1000-grain weight and seed yield per ha, the optimum fertilization rate is found. Comprehensive analyses indicate that the preferred cultivation technique of chicory is the row spacing of 55~60 cm, N 90~120 kg·hm-2, P 65~75 kg·hm-2, K 65~75 kg·hm-2.

摘要:

采用四元二次正交旋转组合设计,以行距(X1)、施氮量(X2)、施磷量(X3)和施钾量(X4)4个因素为控制变量进行田间试验,研究其对菊苣种子千粒重和种子产量的影响,分别建立了其与试验因子的回归模型。对模型解析可得,各因素对千粒重影响大小为氮肥(X2) >钾肥(X4) >磷肥(X3) >行距(X1);对种子产量影响大小为X1(行距) >X2(氮肥) >X3(磷肥) >X4(钾肥)。通过模拟寻优,分别找到菊苣种子千粒重和种子产量的最佳栽培方案。经过综合分析,得到菊苣种子丰产栽培最佳方案为行距55~60cm,施氮量90~120kg·hm-2,施磷量65~75kg·hm-2,施钾量65~75kg·hm-2
