1. Three-dimensional cultivation is a small batch traditional cultivation method. Untie the bag and loosen the plastic film, then stack it, and produce mushrooms at both ends. Generally, 6 to 10 layers or even higher can be stacked. This method is relatively primitive, but because the mushrooms are clean and the moisture content of the mushroom body is low, it is more popular with mushroom farmers. But the fly in the ointment is that the stipe of the finished product is bent, and the cap is likely to fall off during harvesting and transportation, resulting in low commodity value. Moreover, the fungus bag loses water, and the phenomenon of separation from the wall is serious, and side wall mushrooms are prone to occur; three-flush mushrooms are difficult to occur, and the biological efficiency is low.
2. Shelf cultivation. This model is suitable for off-season cultivation and factory production, and can also be used as a reference for mushroom farmers in small-batch cultivation. Folding bottom plastic bags are used for filling, single-head inoculation and single-head fruiting, which can be densely arranged on the cultivation shelf and fruiting upright. The biggest advantage of this method is that the moisture content of the mushroom product is suitable, the mushroom body is round, the flower shape is uniform, the appearance of the product is good, and the product value is high. Moreover, the space of the cultivation site is utilized to the greatest extent, relatively saving the facility investment of the mushroom shed, and improving the capital utilization rate. Its shortcoming is that the one-time investment of the cultivation rack is relatively high, and there are also problems such as the temperature difference between the upper and lower sides and the uneven humidity when the rack layer is too high. It will have a great impact on production.
3. Border cultivation. This mode is suitable for the cultivation of mushroom sheds with large area and good environment, and it is generally carried out after harvesting of fresh mushrooms. Cut off the fungus bag adopting three-dimensional cultivation to become two independent bottomless fungus bags; when adopting the bottom-folding shaped square-bottomed plastic bag, the plastic film at the bottom is scratched and cut off. Build a furrow in the shed with a depth of about 10 cm. After irrigation, place the fungus bag in the furrow and fix it with a small amount of soil. During the fruiting period, water is often poured into the furrow, so that the base material can maintain the water required for the growth and development of fruiting bodies, so its yield is higher than that of the aforementioned mode. Moreover, the size of the mushrooms produced is uniform, the mushroom body is upright and neat, the commodity properties are good, and the commodity value is high. The biggest disadvantage is that it occupies a large area, the utilization rate of the mushroom shed is low, the labor efficiency is low, and the depreciation rate of the fixed assets allocated is also high.
