First, three-dimensional cultivation is a small batch of traditional cultivation methods. The bacteria bag is released and the plastic film is released, and then the palletizing is performed. The two bulbs come out of the mushroom and can generally be 6-10 layers or even higher. This method is relatively primitive, but it is more popular with mushroom farmers because it is clean and the moisture content of the mushroom body is low. However, the fly in the ointment is that the stipe of the finished product is bent, and the caps are easily removed during the process of harvesting and transportation, resulting in a low value of the commodity. Moreover, the water loss of the bag is serious, and it is prone to side-wall mushrooms; Mushrooms are difficult to occur and biologically inefficient. Second, the bed frame cultivation This model is suitable for the off-season cultivation and factory production, the mushroom farmer can also refer to the small-batch cultivation. The use of folded plastic bags, single head inoculation, single-headed mushrooms, can be densely discharged on the shelf, upright mushroom. The biggest advantage of this method is that the mushroom product has a suitable moisture content. The mushroom body is well-rounded, evenly shaped, and the appearance of the product is good. The value of the product is high, and the space of the cultivation place is used to the maximum extent. The facility investment of the mushroom shed is relatively saved, and the The utilization of funds. The disadvantage is that the one-time investment of the cultivation frame is relatively high. At the same time, there are also problems such as different upper and lower temperatures and uneven humidity when the shelf is too high. If the mycelium is not ripe enough, the mushroom bag will lose more water after being exposed. It will have a big impact on production. Third, the medlar cultivation This model is suitable for mushroom shed area, a better environment for cultivation, generally more than one mushroom after harvest. The three-dimensionally cultivated bacteria bag will be cut off and become two independent non-bottom bacteria bags; when the bottom-set plastic bag is used, the bottom plastic film will be cut and cut; After impregnating the water, the bag of bacteria is standing in the pot, and is fixed with a small amount of soil. The water is often poured into the pot during the mushrooming so that the base material can maintain the moisture required for the growth and development of the fruit body, so the output is higher than the foregoing mode; The size of the produced mushroom products is uniform, the mushroom body is regular and orderly, the commodity traits are good, and the commodity value is high. The biggest problem is that the floor space is large, the utilization rate of the mushroom shed is low, the labor efficiency is low, and the depreciation rate of the fixed assets attributable is also high.
