Shiitake waste can be used to produce straw-rotting mushrooms
For more than a decade, the open-field shiitake industry in Xinbin County has developed on a relatively large scale, and the cultivation materials have shown a growth trend. For a long time, the waste material left after fruiting in open-field shiitake cultivation was always returned directly to the fields to improve the soil, and the issue of utilizing the waste material was never studied. In recent years, due to climatic reasons, the open-field shiitake cultivation model has gradually shifted to the cold-frame connected mushroom-column model, and therefore a great many spent mushroom sticks appear every year. This year alone, cold-frame shiitake was developed on 1,560 frames, and after fruiting there will be 7 million kg of spent mushroom sticks. In these waste materials there are still

Causes and Control Techniques of Rotting in Substitute-Material Shiitake Mushroom Logs
In recent years, varying degrees of log rotting (i.e., rotting and disintegration of logs during the spawn-running period) have occurred in some substitute-material shiitake mushroom production areas, causing waste of resources and economic losses for mushroom growers, and in some areas it has seriously threatened the development of the shiitake mushroom industry. For example, in Qingyuan County, the log rotting rates in 1999 and 2003 reached 17% and 31% respectively, with some individual growers exceeding 50%, resulting in severe losses. In response, we have conducted dedicated investigations and research since 1997, and have preliminarily identified the causes of log rotting and its control techniques. 1. Causes of log rotting
