Sowing technique of volvariella volvacea
1. Sowing time. The cultivation of sunny beds should be done well in advance and covered with plastic film in May. The specific sowing date should be determined according to the border temperature, and the general border temperature should be more than 22 ℃. You can't sow seeds if you can't reach them. Seeds are usually sown in central and southern North China in late May or early June.
two。 Seeding quantity. Generally, 1520 kg of rice straw or 15kg of cottonseed husk can be put into the sunny bed per square meter, and the amount of bacteria is 60.8% of the weight of the culture material, that is, 1.2 to 1.5 kg per square meter. If it is cultivated for the first time, the number of bacteria should be appropriately increased to facilitate the success of cultivation.
3. Sowing method. First spread a layer of rice straw or cottonseed husk on the bottom of the border, and then step on it, and spread a circle of bacteria around the edge, with a sowing area of 3-5 cm. Rice straw culture materials should be added around at the same time, such as ring manure, cow dung, chicken dung, cake powder and so on. After the second layer, each additional layer should be 4-6 cm smaller than the edge of the lower layer, and then spread the bacteria around. Generally, there is one layer of culture material and one layer of bacteria, which can be stacked with 3 or 5 layers of culture material. When the temperature is low, the culture material can be thicker, otherwise it can be thinner. After sowing, cover plastic film and grass curtain in the sunny bed in time, pay attention to the change of temperature and humidity, and strengthen management.

What if the straw mushroom is dead?
The reason for the death of straw mushroom is that the ventilation and moisturizing of the mushroom room are not coordinated. Straw mushroom is an aerobic fungus, which needs a lot of water, and it is easy to die from lack of water due to excessive ventilation. Lack of ventilation can easily lead to excessive carbon dioxide and hypoxia death. The temperature of the mushroom room changed suddenly. If there is no early ventilation and cooling in case of continuous high temperature, or if too much well water is sprayed on the floor, and the temperature drops too fast, the mushroom can not withstand the sudden change of temperature and die in batches. Poor germplasm and pests. The bacteria of the right age aged and died because they could not be cultivated in time. The activity of mycelium is poor, and the accumulation of nutrients after sowing is insufficient.

Annual production and cultivation techniques of Straw Mushroom and Coprinus comatus
1.1 volvariella volvacea in 1 crop. Prepare materials for sowing in May, harvest 1 crop a month, harvest 3 tides, and end production at the end of September. 1.2 Coprinus comatus. Sowing seedlings in September, planting mushrooms in the shed in late October, harvesting the first tide in mid-November, inoculating seedlings again in late November, two tides in mid-December, and three tides in the first ten days of January next year. The second crop was planted in late January and production ended at the end of April. 2 cultivation techniques 2.1 production and cultivation techniques of volvariella volvacea 2.1.1 ingredients.
