一、改宽袋栽培为窄袋栽培 生产上常采用25厘米×50厘米的塑料宽街栽培金针菇,但实践证明,宽贷易感染杂菌,而且菇蕾少时,子实体易弯曲,影响质量.达不到盖小、柄长、色浅、肥嫩的优质要求。所以,应以17厘米×33厘米的塑料窄筒为好。 二、改高压灭菌为延时常压灭菌 金针菇是维生素B1、B_2的天然缺陷型,在维生素B_1、B_2含量丰富的培养料上,生长迅速,粉孢子数量较少。但维生素B_1不耐热,在120℃以上时容易迅速分解,所以培养料应以常压灭菌为好。为确保纯菌率,可将灭菌时间由10～12小时延长到13～18小时。 三、改传统立式出菇为卧式两头出菇 装料时,两头接种并各留15厘米左右的筒膜,轻装均压,扎紧袋口,卧式
First, the widening bag cultivation for narrow bag cultivation Production 25 cm × 50 cm plastic wide street mushroom cultivation, but practice proved that wide loan easy to infect bacteria, and mushroom buds less, the fruiting body easy to bend, affecting the quality. Can not reach the small cap, handle length, light color, fat tender quality requirements. Therefore, should be 17 cm × 33 cm plastic narrow tube as well. Second, change the autoclave to delay the atmospheric pressure sterilization Flammulina velutipes is a natural deficiency of vitamin B1, B_2 in vitamin B_1, B_2 rich in culture material, rapid growth, the number of spores less. However, vitamin B_1 is not heat-resistant, it is easy to decompose rapidly when it is above 120 ℃, so the culture material should be sterilized at normal pressure. In order to ensure the pure bacteria rate, the sterilization time can be extended from 10 to 12 hours to 13 to 18 hours. Third, to change the traditional vertical fruiting fruiting two horizontal fruiting loading, the two inoculated and each stay about 15 cm of the film, lightly loaded with pressure, tie tight pocket, horizontal
