摘要
引进美国提色素用万寿菊 3 个品种进行筛选和种植技术的探讨，通过 3 a 的生物学特性、产量、叶黄素含量等的观察结果表明，以橙红品种综合价值最高，深橙品种次之，橙色品种第三。种植密度以 75 000 株 / hm2 为宜，花中叶黄素含量以开花后 12 d 最高。并总结了万寿菊种植配套技术。
varieties of Tagetes erecta were introduced from the U.S.A. for comparison test. 3 years' observations on their biological properties, flower output and pigment content showed that orange red ones had the highest integrated value, then deep orange ones and the last was orange ones. Cultivation density: 75 000 / hm2, xanthophylls content top-ped 12 days after flowering.
