摘    要: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.

关 键 词:红花;氮;磷;钾;吸收

Abstract:The percentage of nitrogen(N),phosphorus (P) and potassium in the safflower plant varied with the growth stages. N,P and K were translocated mainly to growth center of the plant in the life of safflower,facilitating the growth and develOpment of safflower plant. Nutrient contents of the organ were higher when the organ began to form. Nutrient contents in leaves were highest of all organ of safflower plant. In order of the amount, nutrient contents was K,N and P. The total amounts of N,P, K for obtaining 300kg/ha dry flower yield absorbed by safflolower plant Per ha were K2O(490. 5kg) >N (198kg) >P2O5 (103. 5kg). The maximum peak of absorption appeared at the branch and alabasturum forming stage. Nutrient translocation occurred mainly in leaves and stem.
Keywords:safflower  nitrogen  phosphorus  potassium  absorption
