摘　　要：通过盆栽试验,研究5种自制包膜尿素对油菜养分缓释作用及油菜品质的影响。结果表明包膜肥料能够促进油菜的生长发育,做到一次施肥长期供应,满足油菜生长期的养分需求。从油菜的品质来看,包膜肥料提高植株油菜Vc含量为8.3%～48%,提高植株叶绿素含量为8.5%～36%,降低硝酸盐含量为6.4%～13.3%。A pot experiment to study the effects of five kinds of self-sustained-release coated urea on sustained-release and nutrient quality of rape was done.The results showed that coated fertilizer could promote the growth of oilseed rape,so that once fertilization long-term supply of nutrients to meet growing demand for rapeseed.From the quality point of view of rape,rape-coated fertilizer could improve plant Vc content of 8.3%～48%,plant chlorophyll content of 8.5% ～36%,lower nitrate content of 6.4%～13.3%.
