| The study was carried out to understand the distribution, utilization characteristics and industrial development status of straw mushroom germplasm resources in Guangdong, and then provide references for the high efficient, scientific and sustainable development and utilization of straw mushroom germplasm resources to improve the strain quality of the straw mushroom cultivation industry in this region.The species composition and distribution characteristics of Volvariella Speg. resources, the production and utilization status, existing problems and industrial development trend of straw mushroom cultivation were investigated through literature review, field collection and field (plantation or market) survey methods. Guangdong suitable for the occurrence of Volvariella species. There have been more than 20 species reported, accounting for over 70% of the reported species in China. Currently, the main ones used are Volvariella volvacea, V. bombycina, etc., and other wild resources need to be further researched. At the same time, Guangdong is also the most important straw mushroom cultivation and consumption area with long cultivation history in China. However, there is chaos in cultivated strain resources, lack of strain production standards, and no professional strain production enterprises. As the scattered distribution of straw mushroom production enterprises and growers in the Pearl River Delta and its surrounding areas, the lack of large-scale straw mushroom production has made it difficult to improve the competitiveness of the straw mushroom industry in this region. It is recommended to accelerate the development and utilization of wild Volvariella Speg. germplasm resources in this region, develop strain purification and rejuvenation, selection and breeding of high-quality straw mushrooms, and high-efficiency cultivation techniques, and form a germplasm resource bank with regional features. The formulation of superior strain production standards and cultivation of professional mushroom strain production enterprises are the important directions for the development of straw mushroom industry in Guangdong currently. |
