影响磷肥肥效因素的探索研究

Preliminary Study on the Factors Affecting Phosphatic Manure Efficiency

本文对影响磷肥肥效的因素进行了探索研究,结果表明降低土壤pH值,增加土壤水分及与腐殖酸、尿素配合施用,对提高磷肥肥效有显著效果。

The factors affecting phosphatic manure efficiency were sear-ched in this paper. The result showed that decreasing the soil pH value increasing the soil moisture and applying humic acid in combination with urea had remarkable, effect on increasing phosphatic manure efficiency.
