最近几年来,上海市郊的金针菇栽培发展迅速,势头直逼蘑菇和香菇,在生产上各单位都能获得较高的产量和经济效益.为此笔者调查了市郊金针菇的栽培技术并结合自己的经验,总结如下.一、优良品种的选择利用及保存目前市郊各生产单位大都使用了有高产潜力的优良菌株,如黄色品种SFV9,三明一号、白色品种白金系列等,均可作为市郊金针菇的当家品种.黄色品种品质偏脆嫩,白色品种较耐寒,在-5℃时仍有微量生长.在菌株保存方面,有条件保存的单位,可选择当年的优良株进行组织分离,并使用营养条件好的培养基,将菌株提纯复壮,以保存和获取更优质、高产的菌种.菌种宜在低温条件下保存,超低温保存尤佳.二、培养料的合理配比从金针菇的营养生理看,金针菇的蛋白酶具有很强的活性,这就要求在人工合成的培养基内添加较其它菇类更多的氮源,来满足其生理要求,应尽量少用无机氮,因为有较多合成细胞所需的氨基酸不
In recent years, the flammulina cultivation in the suburbs of Shanghai has been developing rapidly with almost the same momentum as mushrooms and shiitake mushrooms, and all the units in the production can obtain higher yield and economic benefits.Therefore, the author investigated the cultivation techniques of mushrooms in the suburbs and combined with their own experience , The summary is as follows.One, the choice of excellent variety utilization and preservation At present, most of the production units in the suburbs use excellent strains with high yield potential, such as yellow variety SFV9, Sanming No.1, white variety platinum series, can be used as the suburbs mushroom Varieties of yellowish varieties of partial crisp tender, white varieties more cold, still a slight growth at -5 ℃ in the strain preservation, the conditional preservation of the unit can choose the good strains of the year for tissue separation, and the use of good nutritional conditions Of the medium, the strain purified and rejuvenated to save and obtain more high-quality, high-yielding strains. Strain should be stored at low temperatures, especially in ultra-low temperature preservation. Second, the reasonable proportion of culture materials from the nutrition physiology of Flammulina velutipes, Flammulina velutipes protease has a strong activity, which requires the addition of artificial media more than other mushrooms nitrogen sources to meet their physiological needs , With inorganic nitrogen should be minimal, because the desired cells more amino acids are synthesized
