Cultivation technology of Phellinus igniarius

Coriolus versicolor is a traditional Chinese medicinal material with high medicinal value. In recent years, with the reduction of wild resources, artificial cultivation has been beneficial, and Coriolus versicolor has been planted and cultivated in many areas. Here I will introduce to you the cultivation technology of Coriolus versicolor .

1. Preparation of mushroom materials

Selection of tree species: Broad-leaved trees such as poplar, birch, oak, mulberry, etc. are all good tree species for cultivating mulberry fungus, but the mulberry fungus grown on mulberry trees has the best medicinal effect. Mulberry trees themselves are also traditional Chinese medicine. This is why mulberry fungus is better than other tree species for cultivating mulberry fungus.

2. Felling period

The best time to fell trees is after they go dormant and before they sprout in the second year, when the trunks are rich in nutrients. Trees can be felled by cutting branches or by thinning. The felled trees should be placed in a ventilated and cool area. Before use, cut the felled trees and branches into 15-20 cm long sections and repair the surface of the sections. Places with knots are prone to fungi and easy to pierce plastic bags, so they should be smoothed and burrs removed to avoid unnecessary losses and waste in production.

3. Preparation of strains

First, select high-quality wheat grains, remove impurities such as insect-infested grains and stones, soak them in hot water, bottle them and sterilize them under high pressure at 121℃ for 1.5 hours. After cooling, the high-quality mother strain of Phellinus igniarius was inoculated under sterile conditions and cultured in a constant temperature chamber at 28°C. Generally, high-quality Phellinus igniarius strains can fill the culture bottle in 30 to 45 days. Since the Coriolus igniarius strains are extremely easy to degenerate, it is important to select vigorously growing strains before inoculation. If degenerate strains are used, not only will they grow slowly, but they will also be easily contaminated by foreign bacteria, causing unnecessary losses to production.

4. Preparation of mushroom sticks

Choose a high-pressure spawn bag with a diameter of 17-25cm×40-45cm, soak the sawn wood sections in water, and put them into the high-pressure spawn bag. Tie the thin branches into handles with a diameter of 16-24cm to avoid puncturing the spawn bag. Put the thick wood sections into high-pressure plastic bags, and fill the two ends of the wood sections with wheat bran and sawdust, which is conducive to the spawn and can prevent the wood thorns on the cross-section of the wood sections from puncturing the spawn bag.

After the mushroom sticks are sterilized, they are inoculated with excellent secondary wheat grain strains. The inoculated mushroom sticks are placed in a constant temperature culture room at 25℃. The suitable growth temperature of Phellinus igniarius is 28℃. Since the mycelium of Phellinus igniarius is weak, the mushroom sticks take a long time to germinate. If the mushroom sticks are cultured at 28℃, a large number of mushroom sticks will be piled up in the germinate room, the miscellaneous fungi will multiply quickly, and the mushroom sticks will be easily contaminated, resulting in waste. Keeping the mushroom sticks at 25°C can reduce contamination.

5. Greenhouse construction

The cultivation of Coriolus versicolor mainly uses plastic greenhouses, which are covered with shade nets or straw mats to facilitate temperature control. If conditions permit, temperature-controlled greenhouses can be used, which is the key to high and stable yields. After the greenhouse is built, bury the finished mushroom sticks in the soil in a U-shape or square shape, with half buried in the soil and half exposed on the soil surface. The mushroom bags can be removed completely or by ring cutting. The fully bagged mushroom sticks are easy to dry, so they need to be covered with wet sand with good moisturizing effect; ring cutting generally has a good moisturizing effect.
