摘要
本文报道了大麦产量、品质与氮、磷、钾化肥施肥量关系的初步研究结果。试验采用二次回归饱和设计,建立了模拟大麦产量、产量性状以及蛋白质含量与氮、磷、钾化肥施用量间关系的回归方程式,即肥料效应函数式。由此分析在不同条件下的肥料效应和提高产量的施肥特点;指出提高籽粒品质的原则,提出了产量和品质兼顾的合理施肥方案和适宜的氮磷钾比例。从而为大麦作物的合理施肥提供了科学依据。
In this paper the investigation on the relationship between barley yield, quality and N, P, K fertilizers treatment was reported. The quadratic regression optimum design was adopted in the field experiment. The fertilizer effect function equations were set up. There were analyses about fertilizers effect on the different conditions. The characteristic and Principle of the application fertilizer for barley yield, quality was summarized and a scheme of rational fertilization was given. The numerical calculation and drawing were performed in a pocket computer.
