生石膏在食用菌培養(yǎng)基中的應(yīng)用屬于輔助原料豆蝠,輔助原料是用于增加營(yíng)養(yǎng)宠纯,改善化學(xué)肤贮、物理狀態(tài)的一類物質(zhì)隧哮,用量較小幽勒。生石膏在食用菌培養(yǎng)基中的添加量在1-3%之間羽历。
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%.
食用菌培養(yǎng)基中添加生石膏在增加營(yíng)養(yǎng)方面的作用:
The effect of adding raw gypsum in edible fungi culture medium on increasing nutrition:
『嘎病(1)直接補(bǔ)充培養(yǎng)基中硫、鈣的不足窄陡;
(1) Direct supplementation of sulphur and calcium in the medium;
】换础(2)使氣態(tài)氮固定成化合態(tài)氮,利于游離在堆料中氨氣的穩(wěn)定跳夭,減少培養(yǎng)基中氮素?fù)p失涂圆;
(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)能加速培養(yǎng)基中機(jī)質(zhì)的分解湃儒,促進(jìn)料中可溶性磷还纤、鉀的釋放,供給菌絲吸收利用氯摆;
(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.

〔毫凇(4)鈣離子能使堆肥中的膠體膜消失,有利于蘑菇菌絲吸收營(yíng)養(yǎng)峡冻;
(4) Calcium ion can make the colloidal film disappear in compost, which is beneficial for mushroom mycelium to absorb nutrients.
“琛(5)生石膏能中和蘑菇菌絲在生長(zhǎng)過程中產(chǎn)生的草酸,并在蘑菇菌絲表面形成有草酸鈣的細(xì)胞膜,有防御外敵咕诊、保護(hù)菌絲的作用 墨攻;
(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)使基料在發(fā)酵后纖維素降解率提高焚卖,可溶性糖增加汹魁。
(6) The degradation rate of cellulose and soluble sugar increased after fermentation.
