在氮、磷、钾肥料不同施用量条件下,调查万寿菊产量及叶片中叶黄素含量变化情况,试验结果表明:氮、磷、钾不同施用量对万寿菊的产量及叶黄素含量影响差异显著。在以菊花为收获产物,以花中叶黄素为最终产品的生产实际中,三种肥料配合施用适宜用量为尿素20kg/hm2、磷酸二铵40kg/hm2、硫酸钾20kg/hm2,此时万寿菊中叶黄素含量达最高。
The results showed that the effects of different application rates of nitrogen, phosphorus and potassium on the yield and lutein content of marigold under different application rates of nitrogen, phosphorus and potassium fertilizers were investigated. Significant. In the production of chrysanthemum as the harvest, the flower lutein as the final product, the three kinds of fertilizer with the appropriate amount of urea 20kg / hm2, DAP 40kg / hm2, potassium sulfate 20kg / hm2, this time marigold Medium lutein content reached the highest.
