摘要：长茎芒毛苣苔是苦苣苔科多年生草本植物，它的叶片正面黄绿相间、叶背面红绿相间，长茎毛芒苣苔既可以做为盆栽花卉也可作为垂吊花卉种植，具有极大的观赏价值。但长茎芒毛苣苔在人工栽培技术等方面尚未有相关研究报道，制约了其在园艺方面的应用。为了探明不同氮磷钾浓度和比例对长茎毛芒苣苔生长的影响，本研究采用“3414”的肥料配比试验进行栽培试验。分别比较其茎叶、根部的鲜重、干重以及不同处理的氮磷钾含量来获取适合的施肥方案。实验结果表明：长茎毛芒苣苔生长最适的氮磷钾浓度比例为N:P:K=3:2：1对应的氮磷钾浓度分别为：0。45g/L、0。15g/L、0。3g/L在这个浓度下总干重约为10。44g分枝数达到了约16枝。75009

The "3414" fertilizer experiment

of Aeschynanthus longicaulis

Abstract: Aeschynanthus longicaul is chrysanthemum mossy perennial herbaceous plants, its leaves are yellow and green facies, leaves red and green on the back, long stems mango moss can be used as potted flowers can also be used as hanging flowers, with great ornamental value。However, there are no related studies in the aspects of artificial cultivation techniques, which have restricted its application in horticulture。 In order to find out the effect of different N, P and K concentrations and proportions on the growth of Aeschynanthus longicaul , the cultivation experiment was carried out by "3414" fertilizer ratio test。Respectively, compared with its stem and leaf, root fresh weight, dry weight and different treatment of nitrogen, phosphorus and potassium content to obtain a suitable fertilization program 。The results showed that the optimum concentration of N, P and K = 3: 2: 1 was 0。45 g / L, 0。15 g / L, 0。3g / L at this concentration the total dry weight of about 10。44g branches reached about 16 branches。
