生产黑木耳投资少、见效快,一年四季均可栽培,但产量低一直困扰着生产者。实践证明,采取以下几项措施,可有效地提高黑木耳的产量。 1.在培养料中添加阔叶木屑 黑本耳是腐生性很强的木腐菌,培养料是黑木耳生长发育的营养基地。因此往培养料中添加含维生素、木质素高且木质疏松的阔叶树木屑,可以有效地提高黑木耳的产量。 2.加大接种量,抑制杂菌生长 为了使黑根霉菌等杂菌得不到养分而失去活力,可采用加大用菌量的办法,增加菌种与培养料的接触面,促使菌种迅速蔓延,占领整个料面。 3.充分满足黑木耳对光照的要求 黑木耳从营养生长转入生殖生长,需要相当强的光照诱导,并且随着木耳子实体的生长对光线要求也逐渐增强。在黑暗条件下,黑木耳菌丝体不能形成子实体。
The production of black fungus less investment, quick, can be cultivated throughout the year, but the output has been plagued by low producers. Practice has proved that the following measures can be taken to effectively improve the black fungus production. 1. In training materials to add hardwood sawdust black ear is very saprophytic wood rot fungi, black fungus culture material is the growth and development of nutrition base. Therefore, adding to the culture material containing vitamins, high lignin and loose woody wood chips, can effectively improve the black fungus production. 2. Increase vaccination to curb the growth of bacteria In order to Rhizopus bacteria and other bacteria can not get the nutrients and vitality, can increase the amount of bacteria way to increase the contact surface bacteria and culture materials to promote bacteria Spread rapidly, occupy the entire surface. 3. Fully meet the black fungus lighting requirements Auricularia into vegetative growth from the vegetative growth, the need for a very strong light-induced, and with the growth of fungus fruiting bodies of light requirements also gradually increased. Under dark conditions, black fungus mycelium can not form fruiting bodies.
