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 trac...
