姜荷花的形态特征及在白云禁毒主题公园的花境应用

Morphological Characteristics of Curcuma alismatifolia and Its Flower Border Application in Baiyun Anti-drug Theme Park

摘要:

姜荷花 Curcuma alismatifolia 要种植在光照充足且排水良好的环境，种植时需消毒土壤及种球，使用缓释复合肥，保持土壤湿润，并及时防治炭疽病及蝗虫等病虫害。参考泰国农业部对姜荷花新品种的测试内容，对广州白云禁毒主题公园中种植的 10 个姜荷花品种的叶片、花序、株高等进行了观察测量。结果表明，10 个品种的株高、冠幅、花序等存在明显差异，应用时应考虑株高等差异；选用、验收姜荷花品种时，可以从叶片中脉、可育苞片、不育苞片、花瓣颜色等进行识别。姜荷花在广州白云禁毒主题公园的花境应用形式是根据其高度和颜色进行搭配，取得了良好的效果。

Abstract:

Curcuma alismatifolia should be planted in an environment with sufficient sunlight and good drainage. When planting, it is necessary to sterilize the soil and seed bulbs, use slow-release compound fertilizers, keep the soil moist, and timely control diseases and insect pests such as anthracnose and locusts. Referring to the testing content of new C. alismatifolia cultivars by the Ministry of Agriculture of Thailand, the leaves, inflorescences and plant heights of 10 cultivars planted in Guangzhou Baiyun Anti-drug Theme Park are observed and measured. The results show that there are obvious differences in plant height, crown width and inflorescence among the 10 cultivars, and the difference in plant height should be considered when applying. When selecting and accepting C. alismatifolia cultivars, it can be identified from the midrib of leaves, fertile bracts, sterile bracts, and petal color. In addition, the flower border application form of C. alismatifolia in Guangzhou Baiyun Anti-drug Theme Park is matched according to height and color, and has achieved good landscape effects.
