目前,国内栽培蘑菇的覆土技术,普遍采用粗、细土粒分两次覆土,还有用粗、中和细土粒分三次覆土的。不同土粒需经过加工筛取分级后,再分期覆土,制作繁琐,劳动强度大。近年来,我县广大菇农在生产中改革了覆土技术,将分次覆粗、细土改为一次覆细土,普遍反映省工易行,效果良好。为了证实一次覆土的可行性,我们于1984年进行了对比试验,现将试验结果报告如下。 At present, the domestic cultivation of mushrooms covering technology, generally used coarse, fine soil divided into two soil cover, but also with coarse, fine and fine soil in three times subsoil. Different soil particles need to go through the processing sieve grading, and then staging the soil, making cumbersome, labor-intensive. In recent years, my county a large number of mushroom farmers in the reform of soil cover technology, will be graded thick, fine soil to a covered soil, generally reflect the provincial workers easily, the effect is good. In order to confirm the feasibility of a soil cover, we conducted a comparative test in 1984, the test results are reported below.
