银白木耳栽培技术研究

A study on the Culture Technics of Auricularia polytricha var. argentea

银白木耳是1987年赵大振首次发现的木耳科、木耳属毛木耳的一个新变种.该变种颜色纯白,朵大肉厚,外观美丽,并具抗木霉污染、耐高温、生物学效率高、营养丰富等优点,是有重要开发利用价值的食用菌.经过三代五次人工驯化培养研究,初步探明了该变种的生物学特性和生育条件,提出了形成良好的菌体结构的三要素——基质的密度、均匀度、表面光滑度,并研究出了“U”型开孔和顶端扣帽封袋、地沟出耳的配套技术,为开发利用这一新的菌类资源提供了科学依据.国家专利局已经受理了《银白木耳菌种与其培养方法及栽培技术》专利,专利号:91102216·3.

Auricularia polytricha (Mont.) Sacc. var. argentea Zhao et Wang is a new variety of the species Auricularia polytricha.lt was discovered by Zhao Dazhen in 1987. The sporophore is pure white. It has desirable characters, namely, its beautiful appearance, big and thick fruit bodies, tolerance to high temperature, resistance to trichoderma contaminations, high biological efficiency, nutritious, and good taste. It has been well proved that it is a kind of edible fungi being of important value to develop. Through five years and three generations acclimatizing cultivation and research, its biological characteristics and condition for growth were found out, three essential factors forming good structure of its body-substrate density, uniformity and its surface smoothness-were advanced, and a complete set of culture technics-making "U" holes on the wall of the culture polybag, sealing the polybag top and then capping it with a piece of plastic film,and hanging the bag in ditch -was worked out. These technics provided a scientific basis for developing and utilizing the edible fungus.
