Development status and countermeasures of soybean industry in Guangxi

【Objective】The development status and existing problems of soybean industry in Guangxi was investigated and analyzed, and solutions were proposed to provide references for promoting the sustainable development of soybean industry.【Method】From 2018 to 2020, field survey on soybean industry of 14 prefecture-level cities in Guangxi was conducted, especially for planting and processing-related cooperatives, enterprises and local agricultural bureaus. Main planting varieties, soybean planting area, regional distribution, processing conditions and raw material sources in Guangxi was mainly investigated. Relevant information and data was collected for analyzing the development status and main problems of Guangxi soybean industry. Countermeasures and suggestions were putted forward.【Result】Soybean was widely planted in Guangxi, and mainly were summer soybeanand autumn soybean(about 72%), followed by spring soybean(about 28%). The planting area and total yield of soybean in Guangxi have been declining in general since 2000.The soybean planting mainly distributed in Guilin, Hechi, Baise, Nanning and Chongzuo. In 2017 and 2018, the soybean output of the five cities accounted for 68.31% and 69.77% of the total output of Guangxi respectively. Most of the soybean in Guangxi was planted sporadically in mountainous dryland and mainly in the way of interplanting with corn, orchard and ridge planting. In production, the renewal speed of new varieties was slow. The spring soybean varieties were still mainly Guichun No.8, Guizao No.2 and local varieties, while the summer soybean varieties were mainly Guixia No.1 and Guixia No.3. From 1992 to 2020, 45 soybean varieties were bred in Guangxi, including 29 spring soybeans and 16 summer soybeans. There were 41 varieties approved by Guangxi Crop Variety Approval Committee, and 9 varieties approved by National(Southern) Crop Variety Approval Committee. Traditional soybean products in Guangxi were mainly processed with dried soya cream, tofu, preserved black bean, fermented bean curd, soy sauce and soybean paste. The raw materials for traditional soybean products were mainly from northeastern China. In the twenty-first century, the processing of soybean press(the main products were oil and soybean meal) was increased, and 100% of the raw materials were imported transgenic soybeans. The main problems existing in the development of soybean industry in Guangxi were as follows:low efficiency of soybean planting and low self-sufficiency rate;serious homogenization of soybean varieties;low utilization rate of soybean processing by-products;few joint researching by scientific research institutes and enterprises.【Suggestion】Increase investment in technological research and development for soybean industry. Multidisciplinary joint researchshould be conducted to solve problems such as small-scale mechanization, soybean low-yield, variety specialization. Strengthen scientific layout and support dominant soybean production regions and key soybean varieties. Increasing the integrated development of the industrial chain and create Gui brand productions. Strengthen cooperation with ASEAN countries to expand the soybean planting market, etc., to promote the sustainable and healthy development of soybean industry in Guangxi.
