1 It is cultivated in a variety of ways, such as the fungus method, the direct method, the regeneration method, and the two-head mushrooming method, and the yield is high;
2 During the budding stage, the number of aeration and ventilation must be increased to make the primordium faster and the number of mushroom buds increased;
3 The mushroom house is kept in darkness, and the light intensity is controlled at about 5lx. At the same time, attention is paid to the low temperature and ventilation conditions, which can make the fruit body white.
4 Reasonably regulate the humidity. In the whole cultivation process, the air humidity is controlled at 80%~90%. 85% ~ 90% of the buds are good, the growth of the stipe is controlled at about 85%; the days before harvesting are reduced to 80%, the product can be kept white, dry, easy to store, and can meet the canning requirements .
In 1989, the Institute of Edible Fungi, Shanghai Academy of Agricultural Sciences began to adopt the hybrid breeding method for the spores and spores of F. velutipes. The SFV2 (Japanese strain) SFV2 (Hong Kong Yellow Strain), a phylogenetically-diverse parental phenotype with large difference in the phenotype of the fruiting bodies, was selected. By polyspore hybridization, three hybrid strains of F89, F107 and F129 were selected from more than 200 strains. Their color is between the two parents, the stipe is darker than SFV9, but lighter than SFV2, the branches are between the two parents, the stipe is straighter than SFV9, and there is no distortion. Caps are thick, involute and not easy to open. The yield per unit of production is 11%~27% higher than that of their parents. According to the report, the selected three strains were genetically stable in the laboratory environment, but in the small-scale promotion experiment, the yield and traits in different regions were not exactly the same. It is estimated that these factors are due to different temperature and environmental factors and have not yet been widely promoted. The introduction of local climate conditions must be taken into account when introducing the species.
