Mushroom is a mushroom mushroom cap that grows in a dry environment. The epidermis is split, exposing a white mushroom, named after the pattern. The mushroom is a treasure of shiitake mushrooms. In the circulation of shiitake mushrooms, the shiitake mushroom is of high quality and high price and is very popular. Therefore, in the development of the production of mushrooms, the purpose of the cultivation of mushroom is not only a market demand, but also a good way for mushroom producers to increase the income of mushrooms. First, the mushroom cultivation conditions mushroom is not a natural mushroom strain characteristics, it is the fruit body in the growth process, under adverse environmental conditions, the resulting high-quality malformed mushrooms, any mushroom strains can form mushroom . The conditions for forming mushroom are dryness, strong light, ventilation, and large temperature difference. We can produce high-quality flowering mushrooms only if we artificially create the conditions for producing mushroom, or if we use natural conditions rationally. 1. Humidity and humidity are the main factors affecting the formation of mushroom. The highest air relative temperature of mushroom formation within the mushroom field is 75% or less, and the optimum relative humidity is 55%-65%. The humidity is too high to form or to form mushroom. Humidity is too low, mushrooms easily dry. When the diameter of the cap is less than 1.5 cm, the suitable humidity is 70%-75%. As the cap grows, the relative humidity gradually decreases. Caps begin to crack at about 2 cm. Under normal growth conditions, such as when the relative humidity of the air is between 55% and 65%, the increase in cracks is proportional to the increase in the size of the cap, that is, the faster the growth of the cap, the increase in cracks. The thicker and faster, if the temperature is around 8-15°C, the best flowering mushroom can be obtained. The dry and wet ground of the mushrooming site will directly affect the appearance of the cap texture and the cracking depth. Therefore, the mushrooming place should be kept dry and ventilated, the ground must not be wet, and the ground should be moist and no mushroom should be formed. In addition, when the water content of the medium is 60% to 65%, the mushroom can be easily formed when the material is cultivated. In the case of wood cultivation, the mushrooms can only grow when the mushrooms themselves are in a state of water shortage, but they can maintain the minimum moisture of the mushrooms. 2. Temperature temperature and temperature difference play an important role in the formation and quality of flowering mushrooms. General low temperature (8-15 °C) easy to form high-quality mushroom, low temperature can make mushroom body grow slowly, dense tissue, thick mushroom meat. Larger temperature difference (8-10 °C) is conducive to the formation of mushroom base, but also conducive to a certain low temperature, low humidity conditions, to accelerate the cracking and cracking of the cap and accelerate the formation of high-quality mushroom. 3. Light cultivation mushroom, give enough direct light, shade too dark, not easy to form mushroom. Insufficient illumination, poor color of the mushroom, and insufficient whiteness. In the different stages of the growth of mushroom, the requirements for light intensity are also different. The young buds (below 2 cm in diameter) cannot withstand the strong light, otherwise they will die in the sun. During the mushroom growth period, strong direct light (light intensity of 1500-2000 lux) is required. In winter and early spring, the radiation intensity of sunlight is weak, and the mushroom farm can let the sun shine directly, which can effectively improve the quality of the mushroom. 4. Ventilation During the formation of the mushroom, a slight flow of wind speeds the promotion of the formation of the mushroom. The breeze can reduce the humidity in the mushroom field, and the wind strength is 1-3, and the speed of the mushroom body surface evaporates too quickly. The immature young mushrooms shrink and shrink. Therefore, the mushroom farm must be both ventilated and windproof. The mushroom farm should be selected in a well-ventilated place, and there must be a certain distance between the mushroom shed and the mushroom shed, and ventilation should not be affected. In the first few lectures, we talked about the cultivation techniques of mushroom and some of the alternative cultivation techniques. No matter what kind of cultivation techniques, the four external environmental factors such as humidity, temperature, light and ventilation are very important during the fruiting stage. In the process of mushroom formation and development, they are mutually reinforcing and mutually restrictive. In the cultivation and management, appropriate measures should be taken according to local conditions. Scientific management according to the cultivation conditions of the mushroom can cultivate high-quality flowering mushrooms, thereby improving the economic benefits of the mushroom production. II. Biology of Biyang Huaru Cultivation Techniques At present, Biyang County, Henan Province, China has the best quality of mushroom substitutes at home and abroad, and is known as the Biyang mushroom family. It is of universal significance to master the technical points of Biyang mushroom cultivation and to guide the mushroom production of all mushroom farmers. 1. The cultivation of large bags is rich in nutrients, and the moisturizing performance inside the bags is good, which is conducive to the formation of large quality mushroom. The size of the bag is 55 cm long, 25 cm in diameter and 3-4 mm thick. 2. Three-dimensional shed indoor bacteria, outdoor shelving fruiting, three-dimensional development of space. Occupies a small area, easy to operate, centralized management. The scaffolding is made of brick and bamboo structure. The shed is 8 meters long and 2.5 meters wide. It is set up with 5 shelves and is planted with 500 bags. The output value is 5,000 yuan. 3. Enhancing the growth of mushrooms is a feature of cultivation of mushroom in Biyang. It can not only regulate the temperature and humidity of mushroom sheds, but also facilitate the formation of mushroom, and it can also prevent the occurrence of diseases and insect pests. 4. The bagging and mushrooming room completes the vegetative growth and reduces the process of bag removal and color conversion, ie, the color is turned and the mushroom is produced. After the mushroom is hatched, the bag is reamed and the mushroom grows outward from the borehole. 5. Variety selection of mushroom formation sooner or later, speed and species related to the general low-temperature varieties tend to form mushrooms quickly. The success rate of Biyang mushroom production model is high, and the flower mushroom rate can reach 90% or more. The technology is mature and the economic benefits are significant. According to statistics, the production value of mushroom per ton of dry material can reach 10,000 yuan, which is the most advanced mode of mushroom production so far and is worthy of promotion and application throughout the country.
