摘　　要：在现代二次回归肥料设计中,“3414”设计,除具有其他二次回归设计所共有的优点外,还具有其独特的优点,既可配置3类7种肥料效应函数的功能。对于N、P、K三因素的肥料试验,首先可配置N、P、K三因素二次肥料效应函数,其次尚可配置NP、NK、PK三种二次肥料效应函数,此外还可配置N、P、K三种一元二次肥料效应函数。这样可从3类7种肥料效应函数中为研究者提供多种施肥信息,大大提高了试验成功率与试验精度。In modern Dual regression,'3414'design has its special merits besides other common advantages. It can obtain 3 types and 7 fertilizer effect functions. For NPK three factor fertilizer experiment, it can be first disposed NPK three factor gradual regression. Secondary it can get NP?NK?PK fertilizer effect functions. In addition, it can be disposed N?P?K fertilizer effect function. It can provide researchers with many fertilizer information from the functions and increase success probability and precision of experiment.
