First, the supply of raw materials is tight. At present, the mushroom planting in Fujian province is still mainly retail-oriented, small-scale, backward management, production is affected by the climate, it is difficult to improve the unit area production technology. Since 2006, mushroom cultivation in most parts of the country has been affected by the decrease of high temperature and planting area, which has resulted in the production of mushroom canned raw materials.
