| 摘 要： | 水培条件下，研究了不同铵硝配比（CK，0/100|T1，15/85|T2，30/70|T3，45/55）对芥蓝产量和品质的影响。结果表明：与CK相比，T2和T3处理显著促进了芥蓝的生长|3个增铵处理均显著提高了芥蓝的品质，其中T2处理芥蓝品质最佳，其产品器官VC、可溶性糖和可溶性蛋白含量最高。T3处理芥蓝品质下降。营养液增铵处理显著降低了芥蓝的硝酸盐含量，并且随着铵态氮比例的增加而逐渐降低。综合产量和品质，营养液增加30%的铵态氮较适合芥蓝的水培。

| Abstract: | The effects of different ammonium and nitrate ratios(CK:0/100,T1:15/85,T2:30/70,T3:45/55)on yield and quality of Chinese kale(Brassica albograbra L.H.Bailey)were studied in nutrient solution culture.The results showed that the growth of Chinese kale was significantly improved by T2 and T3 treatments,comparing with the control(CK)treatment.The quality of Chinese kale was improved in all ammonium enhancement treatments,in which T2 treatment had the highest contents of VC,soluble sugar and soluble protein.But the quality decreased in T3 treatment.Nitrate content was significantly reduced by ammonium enhancement treatments and it decreased with the increase of ammonium and nitrate ratios.Considering yield and quality,T2 treatment is more suitable for Chinese kale growth. |
