Abstract: 【Objective】To provide the theoretical basis for promoting the sustainable development of Canna edulis industry in Guangxi, survey and analysis on development status and existing problems of Guangxi C. edulis industry were conducted, and the corresponding development suggestions were put forward.【Method】Based on the statistic data collection and field survey investigation of 14 prefecture-level cities in Guangxi, the development status and main problems of C. edulis industry in Guangxi were analyzed through the perspectives of planting area, planting varieties, processing products, sales market, enterprise benefits, and put forward targeted suggestions and countermeasures.【Result】In recent years, the planting area of C. edulis in Guangxi has been expanding, and the planting area has exceeded 10000 ha. The main cultivated varieties were Nan'ou No.1 and Guixingyu No.3, and the main planting areas were Hechi, Baise, Nanning, Chongzuo, etc. C. edulis starch and vermicelli were the main processing methods of Guangxi, and the main sales methods were retail and e-commerce. The average yield of C. edulis was 45-75 t/ha, the selling price was 600.0-1000.0 yuan/t, and the benefit was about 30000 yuan/ha. The production model of C. edulis mostly adopted "company+cooperative+base+farmer", which had a good development prospect. But the industry was also facing many difficulties, such as single aging varieties and lack of excellent varieties;the cultivation technology was backward and the enthusiasm of farmers was not high;insufficient investment in science and technology, lagging in the docking of scientific research and industry;the industrial chain was not perfect and the comprehensive utilization rate was low;the processing enterprises were small and scattered, and the degree of industrialization was low, etc. These problems seriously restricted the sustainable development of the C. edulis industry in Guangxi.【Suggestion】Strengthen policy guidance, develop regional advantageous production areas, and create the brand effect;strengthen the collection and utilization of germplasm resources of C. edulis and promote the breeding of new varieties;popularize intensive cultivation technology of C. edulis and improve farmers' enthusiasm for planting;strengthening the scientific and technological research of industry-university-research cooperation, perfecting the industrial chain of C. edulis;integrate processing enterprises and give full play to the leading processing enterprises in order to promote the sustainable development of C. edulis industry in Guangxi.
