摘要: 在潮土、褐土、砂姜黑土3种土壤上,分别自1980和1981年选点布置了氮、磷、钾定位试验。在各个处理中分别从0~20,20~40,40~60,60~80,80~100cm个剖面层次中垂直取土样,然后进行室内分析。结果表明:在不施肥处理、单施氮处理、氮磷配施处理、氮磷钾配施处理,NO-3-N累积量以砂姜黑土为最多,潮土次之,褐土最少。硝态氮在土壤中分布不仅与施氮量有关,而且还与土壤类型有直接关系。不同土壤类型直接影响硝态氮在土壤剖面中的移动。

关键词: 长期施肥, 硝态氮累积, 硝态氮剖面分布

Abstract: The effects of different meaures of fertilizer application on crop yield and accumulation of NO-3-N in the profile of three major soils were studied according to the result of a 18 years located experiment.The results showed that the mixed application of N and P or N,P and K would be an efficient way for raising crop yield and had accumulation of NO-3-N in the profile of three major soils.

Key words: Fertilizer application, Accumulation of NO-3-N, Crop yield, Different soil
