目前,许多食用菌生产者,在出菇时仍采用两头出菇法或覆土出菇法。我们在实践中体会到二者都具有许多优点,也存在许多不足。两头出菇法存在的主要问题是后期营养缺乏,生长势弱,菇体小,产量低。覆土出菇法存在的问题是占地面积大,长出的菇带土,从而影响外观质量。采用立体覆土出菇法,既能解决以上存在的问题,又能集两种方法的优点于一身,它的优点是占地面积小,出菇不带土,后期营养充足,菇体大,产量高。具体做法如下:一、取土。选择富含腐殖质,吸水和保水性好的菜园土,拣去杂物,敲碎土粒,掺入适量腐熟有机肥。 At present, many edible fungus producers still adopt the two-headed fruiting method or the soil-covered fruiting-fruiting method when fruiting. In practice, we realize that both have many advantages and many deficiencies. The main problems of the two fruiting methods are the lack of nutrition in late stage, the weak growth potential, the small body of mushroom and the low yield. Covering the law of fruiting is the problem of large area, grow Mushroom with soil, thus affecting the appearance of quality. Using three-dimensional soil cover mushroom method, both to solve the above problems, but also set the advantages of the two methods in one, it has the advantage of small footprint, fruiting without soil, adequate nutrition later, mushroom body, yield high. Specific practices are as follows: First, earth. Select the rich in humus, water and water retention of the garden soil, pick the debris, knock soil particles, mixed with the amount of maturity of organic fertilizer.
