本文采用二次回归正交旋转组合设计,建立了灌水定额、氮肥和磷肥对辣椒产量的数学模型。研究表明:水、氮、磷三个因素对辣椒产量的影响大小基本相近。灌水量和氮肥、氮肥和磷肥对辣椒产量的耦合作用为负效应,灌水量和磷肥对产量的耦合作用为正效应;筛选出了辣椒稳产、高产的水肥管理措施。
In this paper, quadratic regression orthogonal rotation combined design, the establishment of irrigation quota, nitrogen and phosphorus fertilizer on the yield of pepper mathematical model. The results showed that: water, nitrogen and phosphorus three factors on the pepper yield basically the same size. Irrigation and nitrogen, nitrogen and phosphorus fertilizer on the yield of pepper coupling effect as a negative effect, irrigation and phosphorus fertilizer on the yield of the coupling effect as a positive effect; Screening pepper steady and high yield of water and fertilizer management measures.
