摘要

该文应用二次饱和D最优设计

研究了试区3种不同立地农田生态系统春小麦N、P施肥效应方程

建立起不同适宜性的施肥数学模型

分析研究了N、P肥的主效应和交互效应

计算出不同农田的最佳施肥量.以低位梯田为例

计算出不同产量下N、P肥的用量及最适配比.

Abstract

Based on the field test of saturated D-optimal designs with a匆uare

This paper deals with the response equa-tion of N and P fertilizer

on Spring Whest in three different yild ecosystem in Shanghuang experimental station.The mathmatic model of fertilization with different adaptability has been established

The main effect and mutualeffects of N and P fertilizer have been analized and the optimum of fertilizer required has been caculated according tothe model. fertilizer amount applied and the optimum ratio of N and P of crops grown in low terrace have been cacu-lated as an example.
