The production of white needle mushroom, most of the domestic use of greenhouses for seasonal cultivation in autumn and winter, but in spring and summer due to high temperature can not produce and interrupted. Therefore, the cultivation of white needle mushroom in the freezer from May to September can not only meet the needs of domestic and foreign markets, but also make full use of cold storage to increase profits. Pure white gold mushroom is different from yellow golden mushroom in terms of temperature and humidity, oxygen demand, lightfastness, fungus, mushrooming, etc. Some mushroom farmers have not yet mastered it, so the yield is low and the quality is poor. According to the practice and research, the author discusses some experiences and experiences on the cultivation techniques of pure white gold mushroom, for reference. (1) Renovation and utilization of cold storage Cold storage can be divided into high-temperature storage (fruit cold storage) and low-temperature storage (meat, aquatic product storage) according to temperature. According to construction, it can be divided into above-ground storage, underground storage and cave storage. These cold storages were originally designed for the storage of fruits and vegetables, and their performance is not suitable for the cultivation of white golden mushroom. Therefore, they must be properly modified to meet the environmental conditions of the growth and development of white mushroom. The situation of cold storage is different, and its reconstruction method is also different. From the situation of cold-growing white needle mushroom in Hebei Province, the high-temperature library is better utilized than the low-temperature library; the medium-small library is better than the large library; the ground library is better than the underground library; and the ground library is better than the cave library. If we look at the annual factory cultivation, the cold storage group is better than the single warehouse. No major investment is required for the reconstruction of the cold storage, because the main project and refrigeration equipment are already available, and water, gas, and light conditions must be added. There are basically three types of cold storage utilization: The first is to use the cold storage group for annual factory production. A part of the cold storehouse will be transformed into a bacterium room, a part of the cold storehouse will be transformed into a mushroom room, and then the necessary seed production room, spice room, sterilization room and raw material store will be equipped, self-improvement and self-contained system. The second is to make use of the cold storage room as a summer mushroom room, equipped with a corresponding plastic shed on the ground as a bacterium room, and then build a series of simple facilities such as sterilization, spices, inoculation, and inventory, etc., and production can then be carried out. This method does not delay the storage business, and other aspects of investment are also relatively small. In addition to the fungus on the ground plastic shed, autumn and winter can be planted mushroom, mushroom, can also be planted in the summer straw mushroom. In this way, annual production can also be achieved without affecting the storage business. It can also make full use of the leisure time of cold storage to increase revenue. The third is to form the cold storage consortium with the neighboring refrigerated warehouses. The division of labor cooperates and complements each other, and the interests of various refrigerated warehouses are coordinated according to market rules. For example, a cold store specializes in the production of germs, other cold storage specifically for fruiting, from the price of mushroom bags to coordinate the interests of all parties. It is also possible for one of the cold storage units to rent other cold storage as a mushrooming site. (B) The benefits of cold storage cultivation From the practical experience point of view, the cultivation efficiency of white needle mushroom is generally 1-2 times the investment cost (excluding fixed assets), that is, 100 yuan investment and 100-200 yuan profit. The size of the benefits is not determined by a single factor, but by the combined results of many factors (such as management level, cultivation techniques, cultivation scale, sales price, facilities, staff quality, operation mechanism, etc.). Cold-growing mushroom cultivation, according to the different conditions of the bed frame and the height of the cold storage, can be charged 100-150 pounds per square meter, the daily power consumption per bag is about 1 cent, 50-100% bioconversion rate. If there are four 150 square meters of cold storage, the annual gross income will be about 960,000 yuan, after deducting 360,000 yuan, 100 kg per square meter, four batches a year, 80% conversion rate, and 10,000 yuan per ton of processed mushrooms. Costs (raw materials, wages, plastic bags, water, coal, electricity, transportation, office expenses, and medical expenses excluding fixed assets) can be as high as 600,000 yuan a year. Moreover, the cost of 360,000 yuan is not an investment, but it is divided into 4 inputs, each time only 90,000 yuan. Once delivered, funds can also be recovered in a timely manner. Therefore, about 90,000 yuan of funds can be used throughout the year. Other miscellaneous mushrooms can also be processed into salted mushrooms, but also have some benefits. (3) The problems of cold storage cultivation coordinate the conflict between temperature, humidity, gas and light, and meet the needs of the growth and development of white mushroom. Otherwise, the quality of the mushrooms will not meet the requirements of the goods or the production will be severely reduced, resulting in loss of income. In a cold store in Liuzhou City, Guangxi, in July 1995, four of the warehouses were used to cultivate white gold mushroom, and 40 tons of raw materials were fed. The growth of mycelia in the early period was relatively good and the mushroom failure in the latter period caused a loss of 100,000 yuan. After summing up the lesson, the cold storage of cultivated white needle mushroom must pay attention to the following issues: 1. During the germination period, the temperature is high, the mycelium rapidly ages and declines, and the fungus takes advantage of it and breeds. 2. After the mycelium is well developed, the temperature is reduced, but the temperature is still high (10°C or higher) for the development of the fruit body, which promotes the mushroom body to be long and loose, and quickly ages and lodgings. Mushroom feet grow a lot of hair, stick together into one. The upper part of the mushroom body is infected with mold, or the second tidal mushroom is produced, and the product loses its commercial value. 3. Flammulina velutipes grows high and low in size, its thickness is not spoonful, and the mushroom body loses its elasticity but is not crisp and tender, and it becomes a poor quality product. This indicates that the mushroom did not undergo "inhibition treatment" at the young mushroom stage. During the young mushroom period of the mushroom, the temperature must be reduced to 4-6°C for 4-8 days, which is a necessary condition for the quality of the mushroom.
