Development status and countermeasures of cassava industry in Guangxi

【Objective】In order to provide theoretical basis for promoting the sustainable development of cassava industry in Guangxi, the current situation and main problems of cassava industry in Guangxi were investigated and analyzed. Some development suggestions were put forward from the aspects of breeding varieties, cultivating leading enterprises and building regional advantageous production areas.【Method】Through multi-channel investigation on cassava planting area, regional distribution, main varieties, planting mode, yield, planting benefits, processing and sales, the present situation of Guangxi cassava industry was comprehensively analyzed, the main problems faced by the current industrial development were found out, and the countermeasures and suggestions were put forward accordingly combined with the statistical data of relevant departments and the results of literature review.【Result】Guangxi is the main cassava producing area, with planting area and processing yield accounting for about 70% of the whole country. However, the cassava planting area in Guangxi showed a downward trend year by year from 2017 to 2019. Cassava producing areas were mainly concentrated in Nanning, Wuzhou, Qinzhou, Yulin and Guigang in Guangxi. At present, the main intercropping modes are cassava and watermelon, cassava and peanut, cassava and pepper or cassava and Andrographis paniculata, etc.The main varieties were NZ199, SC205, SC5 and Xinxuan 048. There were 24 industrial cassava processing enterprises that have begun to take shape, and were mainly concentrated in Nanning, Qinzhou, Beihai, Guigang, Chongzuo and Hechi and their main products are starch. The development of cassava industry in Guangxi faced the following problems:the economic benefits of cassava planting were low, and the planting area was declining year by year. Because of the shortage of local raw materials, processing enterprises have increased their dependence on regions outside Guangxi;cassava varieties updated slowly, especially lack of special types of varieties;the environmental protection pressure of cassava starch production was great, and the recycling technology needed to be strengthened;cassava post-production products had a single form, and deep processing technology was backward.【Suggestion】The breeding and promotion of new varieties, the research and demonstration of intercropping and interplanting cultivation techniques, Gui brand building, the basic research of cassava and the integration and research and development of post-harvest processing techniques should be further strengthened. Improve the market competitiveness of cassava industry in all directions and promote the sustainable development of cassava industry in Guangxi.
