云南省是全国岩溶地区石漠化危害程度最深、治理难度最大的省区之一.根据2005年国家林业局发布的统计资料,云南省石漠化土地总面积达288.20万hm2,占云南省总土地面积的7.31％.石漠化地区的生态环境恶劣,给当地人民的生产、生活及经济发展带来了严重的影响,生态环境亟待恢复和重建.根据云南、贵州、广西、重庆等省(区、市)对石漠化治理的经验,在石漠化地区种植金银花既可治理石漠化,又能产生较好的经济效益,是恢复与重建石漠化地区生态环境的有效措施.

金银花(Lonicera japonica Thunb.)为忍冬科忍冬属半常绿藤本植物,又名忍冬、银花、双花等,以干燥的花蕾或初开的花入药.1984年国家中医药管理局将其确定为35种名贵中药材之一.金银花味甘,性寒.归肺、心、胃经.具有清热解毒、疏散风热的功效.用于痈肿疗疮、喉痹、丹毒、热毒血痢、风热感冒、温病发热.金银花主要含绿原酸类、黄酮类化合物、挥发油及三萜等成分.现代药理学研究表明,金银花所含绿原酸、木犀草苷等药理活性成分,对溶血性链球菌、金黄葡萄球菌等多种致病菌及上呼吸道感染致病病毒等有较强的抑制力,还可增强免疫力、抗早孕、护肝、抗肿瘤、消炎、解热、止血(凝血)、抑制肠道吸收胆固醇等,其临床用途非常广泛,可与其它药物配伍用于治疗呼吸道感染、菌痢、急性泌尿系统感染、高血压等40余种病症.

Lonicera japonica mainly grows up in Shangdong and Henan Province in China and its flower bud is commonly used in Chinese traditional medicine.Lonicera japonica Cultivar 'Jiufeng 1' was introduced to Yunnan Province for determining characteristics of growth and florescence,output and quality of flower bud.The plantlets of Lonicera japonica Cultivar 'Jiufeng 1' planted in Yunnan Province grew normally and flowered thrice one year.The weight of a thousand fresh flower buds was 228g,the weight of a thousand dry flower buds was 44g at completely white flower bud stage.The weight of a thousand fresh flower buds was 216g,the weight of a thousand dry flower buds was 35g,the content of chlorogenic acid was 5.30%,the first florescence output of per plantlet was 692.36g and the second florescence output of per plantlet was 443.26g at two white part flower bud stage.
