药用红花Ｎ、Ｐ、Ｋ三要素在整个生育期中，主要向该时期生长最活跃的部位运转，以确保其生长发育所需。在植株各器官形成初期，该器官中的Ｎ、Ｐ、Ｋ含量较高．在植株不同器官中，以叶中的养分含量最高。植株中Ｎ、Ｐ、Ｋ三要素含量的顺序为：Ｋ＞Ｎ＞Ｐ。药用红花对Ｎ、Ｐ、Ｋ养分吸收的高峰时期为分枝孕蕾期，占整个生育期的百分率分别为：８３．３％、５５．４％、５２．９％．Ｋ的吸收主要在生育前期和中期，Ｎ和Ｐ在生育后期还有较大的吸收量。每生产５００ｋｇ干花需吸收Ｋ２Ｏ０．８２ｋｇ、Ｎ０．３２ｋｇ、Ｐ２Ｏ５０．１７ｋｇ．Ｎ、Ｐ、Ｋ养分的转移主要发生在主茎叶和茎，其中以Ｋ的转移率最大．
Medicinal safflower N, P, K three elements throughout the growth period, mainly to the most active part of the period of operation, in order to ensure its growth and development needs. In the early stages of the formation of various organs of plants, the organs have higher N, P and K contents. In different organs of plants, leaves the highest nutrient content. Plant N, P, K three elements in the order: K> N> P. Medicinal Safflower N, P, K nutrient absorption peak during the budding buds, the percentage of the entire growth period were: 83.3%, 55.4%, 52.9%. K absorption mainly in the early and mid-term, N and P in the late growth period there is a greater absorption. Each production of 500kg dried flowers need to absorb K2O0.82kg, N0.32kg, P2O50.17kg. N, P, K nutrient transfer occurs mainly in the main stem leaves and stems, of which K the largest transfer rate.
