从王桢“菌子”篇可知,在1313年前三县菇民足迹已至赣、皖诸省,并已形成生产力,技术已达纯熟程度。一个生产项目从初创到形成生产力,并见诸于王桢农书,如果在时间上要200年的话,那末,我们推论香菇栽培技术由龙、庆、景菇民在公元1100年左右发明,是可以确认的。 From Wang Zhen’s “Fungus” articles, we can see that in the first three counties in 1313, the footprints of Mugumen had reached the provinces of Jiangxi and Anhui and had formed productive forces. The technology had reached a level of sophistication. A production project from the start to form a productive force, and found in the book, Wang Zhen, if the time to 200 years, then we infer that the mushroom cultivation techniques from the dragon, celebrate, King mushroom in about AD 1100, is to confirm of.
