拉丁名：Avonia quinaria 根据llifle网站翻译一些资料给大家参考： 原文： Cultivation and Propagation: Although regarded as a choice and difficult plant, in cultivation it is relatively easy. It is a particular favourite of caudiciform plant enthusiasts. Growth rate: Plants grow very slowly and caudex take many years to enlarge. Clustering in cultivation, if grown correctly, it will reward the grower with generous displays of tiny flowers. Caudex exposure: The remarkable tuberous rootstock (caudex) is often raised 1-3 cm above the soil line so that this can be seen and more readily appreciated. For best results the tuber must be exposed only when plans become mature enough, usually after several years (8-12 or more years) of underground growth, as the exposed caudex will no longer increase in size once it has been lifted above the soil line. Potting medium: Since roots are quite shallow, use a cactus mix or add extra perlite or pumice to regular soil potting soil. A gritty, very free-draining compost is suitable, and clay pots help the plants to dry out between watering. For best results, use a shallow pot, and only use the smallest diameter pot that will accommodate the plant. Fertilization: Need a perfect fertilizer diet in summer. Use preferably a cacti and succulents fertilizer with high potassium content including all micro nutrients and trace elements or slow release fertilizer. Watering Needs: Water normally in the growing season from March to October. No water should ever be allowed to stand around the roots. Keep almost completely dry in winter. The swollen caudex makes it very tolerant of under watering. Hardiness: It is quite frost resistant if kept dry, hardy as low as -5° C. It can be grown outdoors in the summer months to benefit from direct exposure to light, and especially exposure to high summer temperatures. Recommended Temperature Zone: USDA 10-12. Sun Exposure: This plant has an excellent heat tolerance, and need full sun to light shade exposures. High levels of light are needed to flower and for good plant development. Rot: Rot it is only a minor problem with Avonia if the plants are watered and “aired” correctly. If they are not, fungicides won't help all that much. The plant turns immediately to mush when over watered, or watered out of season. Care must be given in watering, keeping them warm and wet while growing, and cooler and dry when dormant. Traditional uses: The dried and pulverized roots and stems were once used as yeast for backing bread and also to brew mead (Honey beer). The fresh corms were also used to treat diabetes they was crushed, boiled and ½ of a cup of decoction taken orally. Reproduction: The seed will loose viability in storage, and may not be viable the following year, so the seed should be planted as soon after harvesting as possible. Germination usually occurs within about a week or two. Seed germinate at 15-21 °C. 摘译一些重要内容： 块根暴露：显著的块根应露出土壤1-3厘米，这样更容易欣赏也更容易被人接受。 盆栽介质：由于根系很浅，用仙人掌盆栽土壤，需排水良好。使用浅的容器，直径尽量小。 浇水需要：生长季节3月至10月间正常浇水。不允许在根周围浇水。冬季保持几乎完全干燥。 阳光需求：韧锦具有优良的耐热性，并需要充分的阳光照射，充足的光照有利于花和的植物生长。 腐烂：如果植物正确浇水和“晒”，腐烂只是一个小问题；否则杀真菌剂不会有什么帮助，过度浇水之后立马腐烂。浇水一定要小心，生长季节保持温暖湿润，休眠状态保持凉爽和干燥。 传统用途：干燥、粉碎的根和茎都曾用于面包酵母也用于酿造蜂蜜啤酒，新鲜的球茎也被用来治疗糖尿病，压碎后煮½一杯汤内服。  原来可以吃啊~
