摘　　要：研究在平作漫灌、垄作沟灌2种灌水方式及4 200、3 600、3 000m3/hm2 3种灌水量的不同栽培模式条件下,金盏花植株氮、磷、钾养分积累和色素含量的变化。结果表明:在相同灌水量下金盏花垄作沟灌植株积累的氮、磷、钾积累量较传统方式的少,垄作沟灌3 600m3/hm2的氮、磷、钾积累量在垄作沟灌处理中最大,且在主要收获期色素含量较高,表明垄作沟灌有利于营养元素运送到花朵中以提高色素的含量,改善金盏花的加工品质。The accumulation of plant nutrition and pigment content in marigold under the different cultivated style of 2 kinds irrigation method of surface flooding irrigation and furrow irrigation,3 kinds irrigation quantity of 4 200,3 600, 3 000 m3/hm^2 were studied. The results showed that the bed planting and furrow irrigation was lower than trandition style on N,P and K accumulated quantity. The N,P and K accumulated quantity of bed planting and furrow irrigation with irrigation of 3 600 ma/hm^2 were the highest in bed planting and furrow irrigation treatments, and the pigment content was also highter than the treatments. So the bed planting and furrow irrigation was contribute to nutrition elements carried to flower to increase pigment content, and ehanceing the processing quality of mariglod.
