农业生产必须讲究经济效益,以最小的投资获得最大的经济收益。研究肥料的增产效应,提高化肥的经济效益,对于促进农业生产的发展,增加经济收益具有重大意义。肥料的增产效应反映在施肥量与产量的数量关系上,是研究肥料经济效益的理论基础,是确定经济最佳施肥点,制定最佳施肥方案的根据。本文主要从施肥量与产量之间的数量关系探讨肥料的经济效应,提出合理施肥的经济界限及其确定方法,为经济合理施肥提供科学依据。
Agricultural production must pay attention to economic benefits, with the smallest investment to obtain the maximum economic benefits. It is of great significance to study the stimulation effects of fertilizers and increase the economic benefits of fertilizers in order to promote the development of agricultural production and increase the economic benefits. Fertilizer yield effect is reflected in the relationship between the amount of fertilizer and yield, is to study the economic benefits of fertilizer, the theoretical basis is to determine the best economic fertilization point, to develop the best fertilization program basis. In this paper, the economic effect of fertilizer is discussed mainly from the relationship between the amount of fertilizer and yield, the economic limit of rational fertilization and its determination method are put forward to provide a scientific basis for economical and rational fertilization.
