  生石膏在食用菌培养基中的应用属于辅助原料,辅助原料是用于增加营养,改善化学、物理状态的一类物质,用量较小。生石膏在食用菌培养基中的添加量在1-3%之间。

  The application of raw gypsum in edible fungi culture medium belongs to auxiliary material, which is a kind of substance used to increase nutrition and improve chemical and physical state with small dosage. The addition of gypsum in edible fungi culture medium ranged from 1% to 3%.
  食用菌培养基中添加生石膏在增加营养方面的作用:
  The effect of adding raw gypsum in edible fungi culture medium on increasing nutrition:
  (1)直接补充培养基中硫、钙的不足;
  (1) Direct supplementation of sulphur and calcium in the medium;
  (2)使气态氮固定成化合态氮,利于游离在堆料中氨气的稳定,减少培养基中氮素损失;
  (2) Fixing gaseous nitrogen into combined nitrogen is beneficial to the stabilization of free ammonia in the stack and the reduction of nitrogen loss in the medium.
  (3)能加速培养基中机质的分解,促进料中可溶性磷、钾的释放,供给菌丝吸收利用;
  (3) It can accelerate the decomposition of organic matter in the medium, promote the release of soluble phosphorus and potassium in the feed, and supply the mycelium for absorption and utilization.

  (4)钙离子能使堆肥中的胶体膜消失,有利于蘑菇菌丝吸收营养;
  (4) Calcium ion can make the colloidal film disappear in compost, which is beneficial for mushroom mycelium to absorb nutrients.
  (5)生石膏能中和蘑菇菌丝在生长过程中产生的草酸,并在蘑菇菌丝表面形成有草酸钙的细胞膜,有防御外敌、保护菌丝的作用 ;
  (5) Gypsum can neutralize the oxalic acid produced by mushroom mycelium during its growth, and form a cell membrane with calcium oxalate on the surface of mushroom mycelium, which has the function of defending foreign enemies and protecting mycelium.
  (6)使基料在发酵后纤维素降解率提高,可溶性糖增加。
  (6) The degradation rate of cellulose and soluble sugar increased after fermentation.
