摘　　要：以野生龙葵为试材,研究了不同栽培条件下(喷施浓度为0.2%、0.3%、0.4%KH2PO4及浇水间隔为2、3、4d)龙葵澳洲茄碱、澳洲茄边碱、总碱含量的变化,明确环境因素对龙葵生物碱积累的影响。结果表明:不同栽培条件下龙葵澳洲茄碱、澳洲茄边碱、总碱含量均有不同。喷施0.3%KH_2PO_4,浇水间隔为2d时龙葵总碱含量最高,综合考虑成本和产量因素,更加适宜实际栽培。综上可知,喷施不同浓度KH_2PO_4对龙葵生物碱含量影响程度有限,而浇水间隔天数对龙葵生物碱含量影响较大。Taking wild Solanum nigrum as test materials, the changes of contents of solasonine, solamargine and total alkali of Solanum nigrum under different cultivation condition combinations （0. 2 %, 0. 3 %, 0. 4 % KH2PO4 and watering interval 2,3,4 days） were studied, to clear the effect of environmental factors on the accumulation of alkaloid content of Solanum rigrurn. The results showed that the contents of solasonine, solamargine and total alkaloid of Solanum nigrum were different under different cultivation condition. Generally, the contents of total alkaloids was the highest through spraying with 0. 3 % KH2 PO4 and watering interval with 2 days. The effects of different cultivation conditions on the content of alkaloids were further analyzed. The results showed that the levels of water supply played an important role than fertilization in effecting alkaloid content of Solanum nigrum.
