综述了尿素在土壤中所产生的变化:土壤短期内pH急剧上升,尿素被土壤利用的效率低,N素损失量大,长期施用尿素导致土壤酸化等.提出尿素与控释尿素对温室大棚中土壤特性的影响、尿素对土壤微量元素的影响及温室效应等方面还有待研究.

The changes of urea in soil were introduced in this paper, which showed as follows: the pH of soil hoiked in a short time; low efficiency of urea utilized by soil; huge loss amount of nitrogen; soil acidification caused by long-term application of nitrogen. It needs to be researched that showed as follows: the impacts of urea and controlled release urea on characters of soil in greenhouse, the impact of urea on trace element in soil and the greenhouse effect etc.
