| 摘 要： | 为了提高肥料利用效率，以盆栽油菜为试材，在水溶肥料中添加不同水平的聚天门冬氨酸，研究聚天门冬氨酸作为肥料增效剂加入肥料中对油菜生长及品质的影响。结果表明：聚天门冬氨酸与肥料结合施用可以增加油菜的叶绿素含量，有利于油菜干物质的积累，促进植株氮磷钾的吸收，提高VC含量，同时降低硝酸盐的含量，以聚天门冬氨酸（为肥料用量的5％）加水溶肥处理效果最好。

| Abstract: | In order to improve the use efficiency of fertilizer , taking potted rape as test materials,adding differ- ent levels of polyaspartic acid in the water soluble fertilizer, effects of different levels polyaspartic acid as syner- gist of fertilizer on growth and quality of rape were studied. The results showed that using the combination of polyaspartic acid and fertilizer could increase rape chlorophyll content, conducive to the accumulation of dry matter of rape, promote the absorption of N,P, K,increase the content of vitamin C and reduce the content of nitrate,treatment E had the best effect. |
