蘑菇栽培者为了提高单产,往往在培养料中加入氮素化肥。但是,加了化肥后若堆制不好,存在氨味,会烧死菌种。国外是用后发酵的方法来消除氨味,国内有采用福尔马林来中和的,但成本高,又有刺激性臭味。为了解决这个问题,作者经过化验分析,发现在培养料中加入明矾这种化学物质,不但能与氨结合成盐类,还能使培养料增加吸附力和持水性,又能调节培养料的酸碱性,保证适合蘑菇生长的需要。两年来的重复试验证明,每平方米加入3两明矾后,产量达15.5斤,比对照(不加明矾的为14斤)增产10％以上。
Mushroom growers in order to improve yield, often in the culture material to join nitrogen fertilizer. However, if fertilizer is added after the bad system, there is ammonia taste, will burn the bacteria. Abroad is the method of post-fermentation to eliminate ammonia taste, the domestic use of formalin to neutralize, but the high cost, there are irritating odor. In order to solve this problem, the author through laboratory analysis found that adding alum in the culture material of this chemical, not only with ammonia into salt, but also make the culture material to increase adsorption and water holding capacity, but also regulate the acidity of the culture material Alkaline, to ensure that the mushroom growth needs. Repeated experiments over the past two years proved that after adding 3 two alum per square meter, the output reached 15.5 kg, which was 10% more than that of the control (14 kg without alum).
