摘　　要：为考察含腐殖酸液体肥(UAN型)在叶菜上的应用效果,以竞品液体肥为对照,以香叶饺子菜、上海青、生菜、菠菜为试验对象,开展了田间小区试验。结果表明:与对照处理相比,冲施含腐殖酸液体肥(UAN型)处理的4种叶菜的株高、地上部和地下部鲜质量均高于对照处理的;上海青和菠菜的叶片叶绿素相对含量(SPAD值)低于对照处理的,香叶饺子菜和生菜的叶片SPAD值高于对照处理的;4种叶菜的维生素C含量低于对照处理的,而硝酸盐含量高于对照处理的。In order to investigate the application effect of liquid fertilizer containing humic acids(UAN type)on leafy vegetables,a field trial is conducted with competitive liquid fertilizer as the control and leaf mustard,Brassica chinensis L.,lettuce,and spinach as the experimental objects.The results show that compared with the control treatment,the plant height,aboveground and underground fresh weight of the four leafy vegetables treated with liquid fertilizer containing humic acids(UAN type)are higher than those of the control treatment.The relative chlorophyll content(SPAD value)of Brassica chinensis L.and spinach leaves is lower than that of the control treatment,while the SPAD value of leaf mustard and lettuce leaves is higher than the control treatment.The vitamin C content of the four leafy vegetables is lower than that of the control treatment,while the nitrate content is higher than that of the control treatment.
