单因素肥料试验
unifactorial fertilizer experiment
导致碑肥效果的较大变化，因此单因素试验的结论是在某种具体条件下得出的局部规律，应用的范围不宜随愈扩大. 单因素肥料试脸最常用的设计方法有随机区组与拉丁方两种。这两种设计方法都采用设重复、局部控侧、随机排列三项基本原理。但随机区组试验只进行一个方向的局部控制。拉丁方设计则有两个方向的局部往侧，常用于精度要求较高的试验。 单因素肥料试脸可以在一处进行，也可在多处地点进行，常常是肥料试验网的主要试验项目。这种肥料试脸网的规棋往往较大.(陶勤南)单因素肥料试验(unifaetorial fer‘ilizer ex-periment)仅有一个人为控制肥料因素的试验。可控因素又可分为数量因素与质t因家，数量因素如施肥量等，质量因素如肥料种类等。将试验因素人工控制于不同的状态称作水平，施肥量试验的不同施肥数t为不同水平;施肥方法中条施、穴施等为不同水平.单因素试验应含有两个或两个以上水平。除试验因素外其他可控因素都需保持在某一固定状态，以保证试验因素不同水平单一差异的可比条件，才能比较出不同水平的效应。单一差异是指除了试验因素有不同水平外，其他因素保持一致.作物品种A施甲肥与品种B施乙肥相比，其差异是品种、肥料两个因家都处于不同水平共同引起，两种效应纠绷在一起称为效应混杂。常规试验设计中应尽量避免效应混杂，以免失去了可比性。 单因素肥料试验目的单纯，试验规模较小，研究结果适应范围较窄.如在酸性缺磷土壤上比较几种不同性质磷肥的肥效，与石灰性土壤得出的结果会有很大区别。即使在同一土壤条件，氮肥施用量的大小也可能
