Abstract：Based on the demand of a new variety of yellow Flammulina velutipes in the traditional culti-vated area in the jurisdiction of the experimental station, and the knowledge gap of the role high-purity culture in the inherence of excellent cultivable traits,we screened yellow Flammulina velutipes strains and demonstrated the technology of its high purity culture preparation.The browning and thickness of stipe,the size of cap and the biological efficiency of the test strains are analyzed using significant difference test.The result showed that the fine strain F2927 with a lighter color and a higher biological efficiency of 128%is selected after two screening tests.Infusion bottles loaded with cotton seed hulls and autoclave technology are employed to prepare the high-purity culture in the demonstration experiment of strain F2927,which effectively guarantees the inherence of fine producing traits.For the cultivation of 5 000 kg substrate,the culture preparation cost was reduced by 360 yuan,and the purity of culture was up to 98%.The yield was increased by 8%~10%and the farmers′income was raised by 2 500~3 000 yuan.
