摘　　要：为了探讨芭蕉芋生产中合理的种植方式,比较了紫叶红花和绿叶黄花2个芭蕉芋品种单芽种和复芽种的农艺性状和产量性状,并进行了不同种植密度和不同留株数试验。结果表明,2个品种的农艺性状和产量性状均以绿叶黄花种较优,单芽种农艺性状和产量均比复芽种差,生产上不宜采用单芽作种;绿叶黄花复芽种较合理的种植密度为80 cm×60 cm,此密度下产量比常规（60 cm×60 cm）种植增加14.75%;田间人工调控每穴留1~5株与自然生长每穴存株相同时,产量均与株数增加呈正相关,在栽培上,生长期间不宜进行疏株处理,保留其自然生长有利增产。The agronomic characters and yield of two Canna edulis varieties were studied under different planting density and different reserved plants per hole to discuss the rational planting pattern in production of Canna edulis.The results showed that the agronomic characters and yield of the variety with green leaf and yellow flower were better than the variety with purple leaf and red flower,the agronomic characters and yield of the variety with multiple buds were better than the variety with single bud,The rational planting density for variety with multiple buds,green leaf and yellow flower was 80cm×60cm and the yield under 80cm×60cm planting density was 14.75% higher than that under 60 cm×60 cm planting density,there was a positive correlation between yield and reserved plants when 1～5 plants per hole was reserved in artificial regulation and natural growth conditions.Therefore,keeping its natural growth is beneficial to yield increase in cultivation of Canna edulis.
