Edible mushroom cultivation has no seasonal restrictions, but the winter conditions in the north are poor. Therefore, the following four points should be noted when cultivating edible mushrooms in winter:
1. Pay attention to the choice of site. In the winter in the north, you should adopt greenhouse heating cultivation methods such as heating and coal stoves. Generally speaking, coal stoves are more suitable in terms of cost and practicality.
2. For Pleurotus ostreatus as an example, it is best to choose a low-cost, easy-to-use raw material cultivation method. The raw material cultivation is a cultivation method in which the culture material is not sterilized by a high temperature and a composting fermentation is adopted. Mix the appropriate amount of water with the culture materials, stack them, cover the plastic sheet and let them warm naturally. When the stock temperature reaches 60°C, turn the edge of the culture medium to the middle, continue the fermentation, and let it warm again. Three times after inoculation can be bagged cultivation. By controlling a certain carbon-nitrogen ratio and high-temperature environmental conditions, it is possible to effectively inhibit the proliferation of miscellaneous bacteria and promote the rapid growth of Pleurotus ostreatus.
3. After actual cultivation, we found that a plastic bag with a size of 18 cm (45 cm) and a length of 30 cm after loading contained 0.6 kg of dry material. This ratio can achieve the best yield. In the bagging mode, two layers of three-layer strains are used, that is, two layers are laid one on top of each other. The addition of a strain of bacteria in the middle is more suitable for intensive production.
4. The method of positioning and mushrooming can be adopted in the management, that is, in order to prevent atrophy of the nutrients in the growth process of Pleurotus ostreatus due to competition, the bag is not opened to allow it to grow from reserved oxygen-enriched holes. Mushroom method. This method can effectively prevent the mushroom plexus caused by the open-mouthed mushrooms to be too large, dead mushrooms and poor quality.
