摘  要:
试验针对中原二季作区的早春拱棚马铃薯,采用"3414"回归组合设计,将在马铃薯栽培过程中三大主要的肥料因子作为研究对象,建立了马铃薯氮磷钾配方施肥模型,通过对建立的数学模型进行综合分析,探讨出氮磷钾单因素对产量的影响、经济最佳施肥量和每公顷45000~52500kg施肥模式。

摘  要:
A Model for formulated fertilization of N-P-K was established according to the study on these three main fertilization factors in cultivation process of potato planted in the small plastic greenhouse in the central plains with two-time crops, using"3414"regression combination design approach. Based on comprehensive analysis of the mathmatical model established, the individual effect of N-P-K on yield, the most economic fertilizer application and fertilization pattern with 45 000~52 500 kg per hectare as target yield were discussed.
