【摘要】 根据对天鹰椒氮肥、最经济的磷肥效应试验,求出天鹰椒的产量依N、P₂O₅用量的回归方程,计算出其最高和最经济的施N量和P₂O₅用量（81.7kg/hm²）,并应用其产量依P₂O₅用量的偏回归曲线,指明其产量依P₂O₅用量呈抛物线效应趋势;应用其产量构成因素及吸收N、Ca、Mg数量依P₂O₅用量的偏回归曲线,阐明P₂O₅施用过量产生负作用,找到P₂O₅过量导致天鹰椒减产的原因和根源。更多还原

【Abstract】 Regression equations to express the relation between fruit yield of the capsicum variety Tianyingjiao （C. a var. fascicalatum Irish）and the N,P₂O₅ application rate were established to estimate the highest and the most economic N and P₂O₅ application. A parabola-like effect was produced on the partial regression curve indicating the relation between yield and P₂O₅ application rate. And it is indicated that the fruit yield decrease was caused by the excess P₂O₅ application according to the partial regression curves indicating the relation between the yielding components and the plant’s N、Ca、Mg absorption.更多还原
