一說到食用菌中添加
濟(jì)南石膏粉，可能大家都不還太清楚吧。作為石膏粉生產(chǎn)廠家，下面小編來為大家講解一下石膏粉在食用菌培養(yǎng)中可以增加哪些作用吧。
When it comes to adding Jinan gypsum powder to edible fungi, we may not be too clear. As a gypsum powder manufacturer, let's talk about what role gypsum powder can play in the cultivation of edible fungi.
1、石膏粉可以直接補(bǔ)充培養(yǎng)基中的硫和鈣的不足；
1. Gypsum powder can directly supplement the deficiency of sulfur and calcium in the medium;
2、石膏粉能加速培養(yǎng)基中機(jī)質(zhì)的分解，促進(jìn)料中可溶性磷、鉀的釋放，供給菌絲吸收利用；
2. Gypsum powder can accelerate the decomposition of organic matter in the culture medium, promote the release of soluble phosphorus and potassium in the material, and supply the mycelia for absorption and utilization;
3、石膏粉有利于蘑菇菌絲吸收營養(yǎng)；
3. Gypsum powder is favorable for mushroom mycelia to absorb nutrients;
4、生石膏能中和蘑菇菌絲在生長過程中產(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、保護(hù)菌絲的作用；
4. Gypsum can neutralize oxalic acid produced during the growth of mushroom mycelia, and form a cell membrane with calcium oxalate on the surface of mushroom mycelia, which has the function of defending foreign enemies and protecting mycelia;
5、石膏粉使基料在發(fā)酵后纖維素降解率提高，可溶性糖增加。
5. Gypsum powder increased the cellulose degradation rate and soluble sugar of the substrate after fermentation.
食用菌培養(yǎng)基中添加生石膏在改善化學(xué)和物理狀態(tài)中的主要作用，如下：
The main role of adding gypsum to the edible fungus culture medium in improving the chemical and physical state is as follows:
1、提高培養(yǎng)基的緩沖能力，由氨氣所引起的，在播種后也會發(fā)生的PH值過高的副作用；
1. Improve the buffer capacity of the culture medium. The side effect of high PH value caused by ammonia gas will also occur after sowing;
2、防止培養(yǎng)基變酸和厭氧發(fā)酵，避免培養(yǎng)基酸堿度出現(xiàn)大的變化；
2. Prevent the medium from becoming acidic and anaerobic fermentation, and avoid large changes in the pH of the medium;
3、增強(qiáng)培養(yǎng)基對某些細(xì)菌細(xì)胞間質(zhì)的凝聚作用，這樣可以減少在堆制過程中由于細(xì)菌的活動，而產(chǎn)生一些破壞培養(yǎng)結(jié)構(gòu)；
3. Enhance the condensation of the culture medium on some bacterial intercellular substance, so as to reduce the damage to the culture structure caused by bacterial activities during the stacking process;
4、有助于培養(yǎng)基降低在覆土?xí)r對添加的一些營養(yǎng)性補(bǔ)充物的敏感性而增加產(chǎn)量；
4. It is helpful to reduce the sensitivity of the culture medium to the added nutrient supplements when covering soil, and increase the yield;
5、生石膏提供的鈣素與其他重金屬離子不同，它無毒性且能使秸稈表面的膠體粒子凝集成大的粒子而沉淀下來，產(chǎn)生凝析現(xiàn)象，形成通氣性好的物理結(jié)構(gòu)，使培養(yǎng)基變得疏松，改善蓄水性和通氣性，促進(jìn)了有益微生物的活動；
5. The calcium element provided by gypsum is different from other heavy metal ions. It is non-toxic and can make the colloidal particles on the straw surface coagulate into large particles and precipitate, resulting in condensation, forming a physical structure with good aeration, making the medium loose, improving the water storage and aeration, and promoting the activities of beneficial microorganisms;
6、生石膏還有很強(qiáng)的吸水性，能提高堆肥的持水能力。
6. Gypsum also has strong water absorption, which can improve the water holding capacity of compost.
The above is the role of gypsum powder in the cultivation of edible fungi that Jinan gypsum powder manufacturer Xiaobian explained to everyone. I hope it will be helpful to you. You can come to our website for more relevant matters http://www.wodeapartment.com Ask about it!
