松茸(Tricholoma matsutake)又叫松口蘑,是一种珍贵的食用真菌。但是它在人工控制下进行培育却非常困难,科学家们虽曾作过很多尝试,将松茸菌提纯培养,使它产生子实体,结果都失败了。日本农林水产省林业土壤试验场土壤微生物研究室主任小川等,采取一种称为“感染菌方式”来培养松茸,为人工栽培松茸提供了新的线索。他们的具体作法是:把松树苗种植在一部分被称为“白”的松茸菌菌落里,让这种菌感染松苗的根部, Tricholoma matsutake, also known as Tricholoma matsutake, is a precious edible fungus. But it is very difficult to nurture under artificial control. Although scientists have made many attempts to purify and cultivate Tricholoma matsutake and make it produce fruiting bodies, the results have failed. Ogawa, director of the Soil Microbiology Laboratory at Japan’s Ministry of Agriculture, Forestry and Fisheries, adopted a method called “Infection Bacteria” to cultivate matsutake and provided new clues for artificial matsutake. Their specific practice is: the pine seedlings planted in a part of the so-called “white” Matsutake mushroom colonies, let this bacteria infect the roots of pine seedlings,
