利用废菌糠提高覆土持水力和蘑菇产量的研究

Study on Improving Maximum Moisture Capacity of CasingSoil by Adding Waste Compost in Garden Soil

本文利用平菇等食用菌的废菌糠 ,经适当无氧发酵等一系列处理后添加到普通泥土中 ,使其最大持水力提高至 5 1 3% ,单产提高 13 6 %

The maximum moisture capacity of casing soil is the main factor to influence the yield and quality of Agaricus bisporus.The garden soil which is the most widely used in China restrict the improvement of yield because its maximum moisture capacity is only 20%～30%.The maximum moisture capacity of peat is much higher(80%～90%)but its source is rare in China,it is so expensive that the Chinese farmer can not afford it.By adding waste compost which have been fermented in non-air condition to graden soil,the maximum moisture capacity was increased to 51%,the yield was inceased by 13.6%.
