Edible fungus winter cultivation technology

To cultivate high-yield, high-efficiency, high-quality, and low-cost edible mushrooms such as oyster mushrooms and shiitake mushrooms in the winter, we should start from the following aspects.

First, the factory. Edible mushrooms are cultivated in a variety of ways. In the cold winter months, it is most appropriate to cultivate in room temperature. Indoor heating methods include pipe heating, coal stoves, etc., and taking into account the cost and practicality, the use of coal furnace heating is the most effective, the device is suitable for relatively cold areas, can achieve low cost, rapid heating, and convenient operation. In the cold season cultivation of mushroom and other edible mushrooms, pest damage is light, the rate of contamination of bacteria is low, high yield and stable production performance, mushroom body cover, cover thick, short handle, good color quality, high quality. And fewer vegetables in winter, it is easy to occupy the market and get the desired benefits.

Second, raw materials. The choice of raw materials is very important. For example, Pleurotus ostreatus is the most easily cultivated mushroom in edible fungi. The method of cultivation is simple and the methods are various. Among them, raw material cultivation with low cost and easy operation is the first choice. The cultivation materials include raw material cultivation and clinker cultivation. Raw material cultivation means that the culture materials are not sterilized by high temperature, and generally the method of composting is adopted. After the medium is about to be cultured and mixed with water, pile it up and cover it with a plastic sheet to allow it to warm naturally. Each time the core temperature of the pile reaches 60°C, turn the edge of the material to the middle and continue to stuff it, let it warm up again. . After 3 times, it can be inoculated and bagged. 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.

Third, bagging. For bagged culture materials, some people think that small bags charge less, the cycle is short, but the output is low, time-consuming; Some people think that large bags of material, high yield, but the long cycle, the efficiency is not high. Through the comparison of cultivation experiments, it was found that the plastic bag had a specification of 1845 cm (30 cm after loading), and it was best to put 0.6 kg of dry material. In the bagging mode, two layers of three-layer strains of bacteria are applied, that is, two layers are laid one on top of each other and a strain of bacteria is sandwiched between them, which is more suitable for intensive production.

Fourth, management. Can take the positioning mushroom method. Pleurotus ostreatus, etc. from the bag hole when reserved for oxygen growth, can effectively prevent mushroom buds in the growth process due to competition for nutrients and form a lot of shrinkage, resulting in unnecessary loss of nutrients. The conventional opening of the mushroom, the mushroom plexus is too large, the dead mushroom is more, and the quality of the mushroom is poor. The positioning mushroom method does not open the mouth, the bag of evaporation of water is less.
