为研究不同磷肥和钾肥耦合对蔬菜品质的影响，以茼蒿为试验材料，通过盆栽试验，研究不同浓度磷肥施用并配施不同种类钾肥下茼蒿维生素C(Vc)，还原糖和氨基酸含量。结果表明：同等磷肥施用量条件下，配施不同钾肥处理茼蒿Vc、还原糖、氨基酸含量整体上分别表现为KH2PO4＞KNO3＞KCl＞K2SO4＞CK、KH2PO4＞K2SO4＞KNO3＞KCl＞CK和KH2PO4＞KNO3＞CK＞K2SO4＞KCl；不同磷肥施用量配施同种钾肥时，茼蒿Vc、还原糖、氨基酸含量普遍表现为随磷肥用量的增加而增加；配合KH2PO4施用在不同磷肥施用量条件下茼蒿Vc、还原糖、氨基酸含量均最高，其中在高水平Ca(H2PO4)2条件下配施KH2PO4，茼蒿Vc、还原糖、氨基酸含量达最大值。
為研究不同燐肥和鉀肥耦閤對蔬菜品質的影響，以茼蒿為試驗材料，通過盆栽試驗，研究不同濃度燐肥施用併配施不同種類鉀肥下茼蒿維生素C(Vc)，還原糖和氨基痠含量。結果錶明：同等燐肥施用量條件下，配施不同鉀肥處理茼蒿Vc、還原糖、氨基痠含量整體上分彆錶現為KH2PO4＞KNO3＞KCl＞K2SO4＞CK、KH2PO4＞K2SO4＞KNO3＞KCl＞CK和KH2PO4＞KNO3＞CK＞K2SO4＞KCl；不同燐肥施用量配施同種鉀肥時，茼蒿Vc、還原糖、氨基痠含量普遍錶現為隨燐肥用量的增加而增加；配閤KH2PO4施用在不同燐肥施用量條件下茼蒿Vc、還原糖、氨基痠含量均最高，其中在高水平Ca(H2PO4)2條件下配施KH2PO4，茼蒿Vc、還原糖、氨基痠含量達最大值。

In order to understand the effect of phosphorous and potassium fertilizer on the quality of Chrysanthemum coronarium, a container experiment was conducted to study the concentrations of vitamin C, reducing sugar and amino acid of C. coronarium under combined application of different phosphorus (P) levels and different potassium (K) fertilizers. The main results showed that under the combined application of the same level of P fertilizer and different K fertilizers, the concentration of vitamin C in C. coronarium decreased in this order:KH2PO4>KNO3>KCl>K2SO4>CK, the concentration of reducing sugar decreased in this order:KH2PO4>K2SO4>KNO3>KCl>CK, and the concentration of amino acid decreased in the order: KH2PO4>KNO3>CK>K2SO4>KCl. With combined application of the same K fertilizer and different P levels, we found that the concentration of vitamin C, reducing sugar and amino acid increased with higher P level. In addition, the concentrations of vitamin C, reducing sugar and amino acid were the highest with combined application of KH2PO4 and high P fertilizer.
