食用菌富硒栽培的多種方式
     目前，國(guó)內(nèi)外已對(duì)多種食用菌進(jìn)行了富硒栽培研究及生產(chǎn)，諸如：金針菇、平菇、靈芝、猴頭菇、木耳、香菇、茶樹(shù)菇、秀珍菇、雞腿菇等。由于不同食用菌對(duì)硒的耐受力和富集力不同且差異較大，所以在生產(chǎn)中常常根據(jù)品種的特性進(jìn)行硒的添加。通過(guò)綜合考慮硒的添加方式、生產(chǎn)方式、添加量、菌體（絲）產(chǎn)量、富集力、回收率、生產(chǎn)成本和安全性，來(lái)確定具體菇種的生產(chǎn)方式。 
       常見(jiàn)的硒的添加方式有：有機(jī)硒肥實(shí)現(xiàn)轉(zhuǎn)化或以天然富硒原料（雜木、麩皮）作為培養(yǎng)料進(jìn)行栽培。后者是目前的研究熱點(diǎn)所在，尤其是在富硒地域利用天然的富硒原料、土壤、水進(jìn)行栽培，具有可持續(xù)性、自然特性好、成本低的特點(diǎn)。如：利用富硒大豆進(jìn)行靈芝菌液發(fā)酵；利用富硒原料對(duì)香菇、平菇、姬菇進(jìn)行栽培研究，發(fā)現(xiàn)栽培基質(zhì)含硒量與栽培所得食用菌含硒量成正比。 
   　在生產(chǎn)方式的選擇上，通常為液態(tài)發(fā)酵培養(yǎng)和固態(tài)基料培養(yǎng)兩種，發(fā)酵生產(chǎn)是目前富硒培養(yǎng)的主要方式。發(fā)酵生產(chǎn)有周期短、產(chǎn)率高、富集條件易控制等優(yōu)勢(shì)，所以眾多的食用菌生產(chǎn)廠家均采用此種方式進(jìn)行大規(guī)模生產(chǎn)，相應(yīng)的發(fā)酵條件的摸索也較多。  
4、富硒食用菌的復(fù)合產(chǎn)品研發(fā) 
      目前，市場(chǎng)上已有多種富硒食用菌產(chǎn)品，涉及富硒香菇、富硒花菇、富硒靈芝、富硒黃絲菌、富硒灰花樹(shù)等，還有許多富硒食用菌切片、精粉、硒多糖、硒蛋白及一些復(fù)合產(chǎn)品。

At present, many kinds of edible fungi have been studied and produced by selenium-enriched cultivation at home and abroad, such as: Flammulina Velutipes, Pleurotus Ostreatus, Ganoderma Lucidum, hericium Erinaceus, Auricularia Auricula, Shiitake mushroom, agrocybe AEGERITA, pleurotus Ostreatus, Coprinus Comatus, etc. . Because different edible fungi have different tolerance and concentration of selenium, selenium is often added according to the characteristics of varieties in production. The mode of production of specific species of mushroom was determined by comprehensive consideration of se addition mode, se mode of production, se addition amount, se production, SE enrichment, se recovery rate, se production cost and se safety. The common ways of adding selenium are: Organic Selenium Fertilizer is transformed or natural selenium-rich raw material (miscellaneous wood, bran) is used as culture medium. The latter is the focus of current research, especially in selenium-rich areas using natural selenium-rich raw materials, soil, water for cultivation, with sustainability, good natural characteristics, low cost characteristics. For example, se-enriched soybean was used for Ganoderma lucidum liquid fermentation, and se-enriched material was used for the cultivation of lentinus edodes, pleurotus ostreatus and Hypsizygus Marmoreus. In the choice of mode of production, liquid and solid substrate culture are usually used, and fermentation is the main method of selenium enrichment. Because of the advantages of short period, high yield and easy control of enrichment conditions, many edible fungi manufacturers adopt this method for large-scale production, and the corresponding fermentation conditions are also explored. 4. Research and development of composite products of selenium-rich edible fungi. At present, there are many kinds of selenium-rich edible fungi products on the market, including selenium-rich lentinus Edodes, selenium-rich flower mushrooms, selenium-rich Ganoderma Lucidum, selenium-rich yellow Hypha, selenium-rich ash tree, etc. , there are many selenium-rich edible mushroom slices, refined powder, selenium polysaccharide, selenoprotein and some complex products.
