Tea tree mushrooms are rich in nutrients, protein content of up to 19.55%. The protein contained in 18 kinds of amino acids, of which the highest content is methionine accounted for 2.49%, followed by glutamic acid, aspartic acid, isoleucine, glycine and alanine. The total amino acid content is 16.86%. The content of 8 kinds of essential amino acids is complete, and there are rich B vitamins and potassium, sodium, calcium, magnesium, iron, zinc and other mineral elements. Chinese medicine believes that the mushroom is sweet and warm, non-toxic, has the effect of strengthening the spleen and stopping diarrhea, and has a special role in anti-aging, lowering cholesterol, cancer prevention and anti-cancer.
1. Nutrition. Tea tree mushroom is a kind of wood-rotting fungus with weak decomposition ability of lignin and cellulose. Wild tea tree mushroom is only born on the oil tea tree. After artificial domestication, oil tree, maple, willow, oak, aspen and other broad-leaved trees can be used as cultivation materials, but the material is more sparse, containing less tannin components of the wood chips are more adapted to the growth of tea tree mushrooms. You can make full use of bran, rice bran, cake fertilizer, etc. as nitrogen source.
In addition to the utilization of wood chips, bagasse, straw, cottonseed husk, mycorrhizal grass can also be used as a carbon source. Carbon source in single and double sugar is the best, starch, cellulose and other utilization capacity is weak. If the cultivation material formula contains only glucose, mycelial growth is more sparse, and with a small amount of sucrose, the mycelial growth is dense and vigorous. This indicates that the mycelium growth process requires mineral elements related.
2. Temperature. Tea tree mushroom is a medium temperature edible fungus. On PDA medium, under 26℃, the spores germinated after 24 hours, and the microscopic mycelium could be seen by naked eyes after 48 hours. The optimal temperature for mycelium growth is 23～28℃, and it stops growing above 34℃, and it can be stored for 3 months at -4℃. The temperature range of the protoplast differentiation of the substrate is 12～26℃, the optimum temperature is 18～24℃, lower or higher temperature will delay the protoplast differentiation. Lower temperature, the growth of the substrate is slow, but the organization is strong, the mushroom shape is larger, and the quality is good; higher temperature, it is easy to open the umbrella and form the long-stalked thin cap mushroom.
3. Moisture. Tea tree mushroom cultivation medium moisture content should be mastered at 60% ~ 65%, that is, grab a handful of medium with your hand, pinch it with strength, wet between your fingers, slightly water but not flowing down, loosen your fingers into a block, and spread it out when it falls to the ground as appropriate. However, different types of wood chips and thickness of different slightly different, should be flexible. Mycelium growth, the relative humidity of the air requires less than 70%; the formation and development of the substrate for 85% to 95%, the growth period is appropriately reduced to extend the product freshness period.
4. Air. Tea tree mushrooms are aerobic large fungi, very sensitive to carbon dioxide, poor aeration of carbon dioxide concentration is too high, easy to cause slow growth of mycelium, the substrate stipe thick and long, the cap is small, early open umbrella, deformed mushrooms.
5. Light. Tea tree mushroom is a light-demanding fungus, the substrate has phototropic growth characteristics, suitable diffuse light is necessary to complete the normal life history. During the mycelium culture period, it still grows in the absence of light, but does not form the substrate. The substrate is not easy to differentiate without light, and the appropriate light intensity is 50-300 lux.
6. pH. Tea tree mushroom mycelium like weak acidic environment, optimal pH 5.5 ~ 6.5, pH 4 or 6.5 or more mycelium growth sparse, slow.
