Abstract

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。
