花叶芋(Caladium bicolor),属天南星科花叶芋属中的观叶植物。它叶片硕大,色彩斑斓,观赏价值很高。但花叶芋块茎不易保存,1988～1985年冬季我们有近15000个块茎由于贮存不当而所剩无几,造成很大的经济损失。本文就这一问题进行了探讨。 1 材料和方法 1.1 材料 4月移栽的花叶芋试管苗,7月盆栽,11月挖出块茎。 1.2 方法 在10月下旬花叶芋叶片逐渐变黄时,控制水分,至11月上旬停止浇水,待叶片全部变黄于瘪后取出块茎,去泥,晾干后贮存。 1.2.1 温室内盆贮:花盆两两对扣,每15d向花盆上喷一次水。 1.2.2 房间内加温贮存 1.2.2.1 袋贮:将晾干的块茎放在塑料袋中,扎紧袋口,置于距地面1.5m处。 1.2.2.2 纸盒贮:将晾干的块茎放在纸盒
Caladium bicolor is a foliage plant in the genus Araceae. Its huge leaves, colorful, ornamental value is high. However, tuberous stems are difficult to preserve. From the winter of 1988 to 1985, nearly 15,000 tubers were scarcely stored due to improper storage, resulting in great economic losses. This article explores this issue. 1 Materials and Methods 1.1 Materials April transplanted cucumber tube plantlets, potted in July, November tubers. 1.2 Methods In late October when leaves gradually turn yellow, the control of water until early November to stop watering until all leaves turn yellow after deflated tubers, to the mud, dried and stored. 1.2.1 pots in the greenhouse storage: two pairs of flower pot buckle, spray water once every 15d to the pot. 1.2.2 room heating storage 1.2.2.1 bag storage: the tubers will be dried in plastic bags, tie tight pocket, placed 1.5m away from the ground. 1.2.2.2 Tray Storage: Place the dried tubers in the tray
