长期以来,在蘑菇生产中都是采用粗、细土粒两次覆土,不仅工艺烦琐,劳动强度大,且往往遇雨天不能制作大小土粒而耽误了覆土时机。改革覆土材料和方法,是广大蘑菇栽培者的迫切愿望。为此,我们进行了六种覆土材料的对比试验。一、材料与方法(二)覆土材料①炭泥:粉状煤烧后的灰渣。②泥炭:若干年前植物埋藏在土层下形成的。③散状土:土表下13～15厘米的松散中壤土,大的直径为1～1.5厘米,小的为0.3～0.5厘米。④砻糠泥浆土:稻壳在5%石
For a long time, the mushroom production is the use of coarse, fine soil twice covered soil, not only tedious process, labor-intensive, and often in the rainy days can not make the size of soil particles and delayed soil cover timing. The reform of soil-covering materials and methods is the urgent desire of mushroom growers. To this end, we conducted a comparative test of six soil-covering materials. First, the materials and methods (B) Cover material ① carbon mud: powder coal ash after burning. ② peat: a few years ago buried in the soil formed under the soil. ③ loose soil: soil surface 13 to 15 cm loose loam, large diameter of 1 to 1.5 cm, a small of 0.3 to 0.5 cm. ④ 砻 bran mud soil: rice hull in 5% stone
