摘要：

为提高工厂化育苗生产效率，降低生产成本，方便管理者取得简单易用的肥料，试验以菇渣有机复合基质为育苗基质，以缓效氮肥草酰胺为肥源，番茄为试验材料，采用穴盘育苗法研究了草酰胺在培育番茄壮苗中的施肥效果。结果表明，与施速效肥尿素基质EC值相比，在整个育苗过程中，施缓效肥草酰胺的育苗基质EC值变化平缓，呈现缓慢上升而后缓慢下降的趋势；草酰胺施肥处理能够促进番茄幼苗对N、P、K营养元素的均衡吸收，利于鲜重、干重的快速积累，幼苗生长较快，株高、茎粗和叶绿素含量显著高于尿素处理，幼苗生长健壮。表明草酰胺是培育壮苗的优良氮肥肥源，能够促进番茄壮苗形成，操作简单，适于工厂化育苗使用。

Abstract:

In order to improve the industrialized breeding production efficiency, lower the production cost, and make the fertilizer been convenient for the manufacturer to obtain in brief and easily, research was conducted to study effects of low release nitrogen fertilizer of oxamide on vegetative growth of tomato seedling grown in the substrate of mushroom dregs. The results showed that, compared with the substrate with application with urea, EC value dynamic change of the substrate with application of oxamide was steady, increased slowly at first and then decreased slowly. Oxamide fertilizer could induce N, P and K nutrients balanced absorption by tomato seedling, and dry weight and fresh weight accumulation in seedlings. So tomato seedlings grew fast and healthy. Plant weight, stem diameter and chlorophyll content of tomato seedling grown on substrate were higher with application of oxamide fertilizer than with application of urea. In collusion, oxamide is the good N fertilizer in industrialized breeding due to promoting healthy seedling and operation was simple.
