平菇是我省栽培面积最大的菇类,每年投料(棉籽壳)约4000万公斤,产鲜菇约3600万公斤,产值约4860万元。近年来,虽然在培养基配方、栽培方式和管理方法上都有了较大的改进,但其产量仍不稳定,平均生物效率仅90%左右,特别是霉菌污染对菇农的威胁更大。为此从1985年起,我们采用佛罗里达平菇和枣庄117粗皮侧耳两个菌株,进行了高产栽培试验.1985年和1986年分别投棉籽壳料1750公斤和2500公斤,生物效率达150.1%和158.6%.现将其栽培技术报道如下。一、培育优良菌种(一)母种培育:优良的母种是获得高产的第一步.经多次试验表明,以每年进行一次组织分离,挑选性状优良的母种做扩大种,采用PDA 加富培养基
Pleurotus ostreatus is the largest mushroom cultivation area in our province, with an annual output of about 40 million kilograms of cotton seed hulls and about 36 million kilograms of fresh mushrooms, with an output value of about 48.6 million yuan. In recent years, although the medium formula, cultivation methods and management methods have been greatly improved, but its output is still unstable, the average biological efficiency of only about 90%, especially the greater the threat of mold pollution mushrooms farmers. For this reason, we used two strains of Pleurotus ostreatus and Zanthoxylum scabra 117 to carry out high-yielding cultivation experiment since 1985. In 1985 and 1986, 1750 kilograms and 2500 kilograms of cotton seed hulls were cast, the biological efficiency reached 150.1% and 158.6 %. Now its cultivation techniques are reported as follows. First, to cultivate fine strains (A) Breeding of mother: good mother is the first step to obtain high yield.Through several experiments show that once a year to organize the separation, selection of good traits of the mother to do to expand the species, the use of PDA Rich media
