| 摘 要： | 采用模拟土柱试验方法,通过连续种植2茬蔬菜,研究7种不同施肥模式即:不施肥,化肥(基施),化肥(基、追肥各半),化肥+双氰胺(基施),化肥+双氰胺(基、追肥各半),化肥+有机肥(N各半),有机肥(基施)]对蔬菜产量、硝酸盐含量及模拟土柱氮、磷随渗漏水淋溶损失的影响.结果表明,"化肥+双氰胺(基施)"和"有机肥(基施)"2种施肥模式,不仅能使蔬菜获得较高的产量、硝酸盐含量较低,还能明显减少蔬菜种植期间模拟土柱硝态氮、铵态氮和水溶性总磷随渗漏水淋溶的损失量,从而有效减少菜地土壤的氮、磷对地下水造成的农业面源污染. |

| Abstract: | A fertilization experiment was carried out on two cropping of vegetables growing in simulated soil column.The experiment was designed to have 7 fertilization patterns i.e.(1)CK or no fertilizer,(2)chemical fertilizer applied as basal dressing,(3)chemical fertilizer applied half as basal dressing and half as side-dressing,(4)chemical fertilizer and dicyandiamide applied as basal dressing,(5)chemical fertilizer and dicyandiamide applied half as basal dressing and half as side-dressing,(6)chemical fertilizer ... |
| Keywords: | vegetable fertilization pattern yield nitrate content loss of nitrogen and phosphorus |
