First, control the temperature The temperature range for ear growth is 16°C~35°C. The most suitable growth temperature is 24°C~28°C. In this temperature range, the higher the temperature, the faster the ear piece grows. When the temperature is lower than 18°C, the ear piece grows. Slowly, the ear growth is inhibited when the temperature exceeds 35°C. When the temperature is lower than 20°C, ventilation should be reduced and insulation work should be done. When the temperature exceeds 33°C, it is necessary to pay attention to spray water cooling and strengthen ventilation. Second, adjust the humidity The ear development stage requires 85% to 95% relative air humidity. The relative humidity of the air can be maintained by artificial water spray. When water is sprayed, the water pipe can directly spray to the ear piece and space, but mainly to the space and the ground. Watering. Spray water according to the climate, the growth of the ear may be, sunny, high temperature, large ears, the amount of water spray, spray 3 to 4 times a day; cloudy, ear hours, less water or Do not spray water. When the edge of the tab is curled, blackened and hardened, it indicates that the humidity in the environment is insufficient, and the water must be sprayed in time. Ear hair pieces have strong drought tolerance, even if the ears become black and hard, dry and curly, water spray water recovery, but also to restore growth, so management should take dry and wet latent, so that the environment is dry Wet and wet conditions help improve the quality and yield of the tabs. During the high temperature period, special wet and dry alternation management must be performed. If it is exposed to high temperature and high humidity for a long period of time, it is easy to cause “flowing earsâ€. After each water spray, combined with ventilation, the excessive water on the ear piece can be dissipated. . In continuous rainy days, it is necessary to increase ventilation and prevent air leakage. Third, increase the light The intensity of light has a great influence on the quality of the lugs. Under strong light, the grown lugs are thick, dark and soft, and the hair is thick and long. After the lugs are dry, they are black. In low light or close to dark environment, the color of the ear is light, reddish, the ear is thin, the villi of the ventral surface is thin and short, and is not obvious. After drying, the ear is red-brown and translucent. Therefore, by adjusting the light intensity of the ear environment, different quality ear pieces can be produced to meet the needs of the market. Fourth, keep ventilated During the growth and development of the ear, a large amount of oxygen is absorbed and carbon dioxide is exhausted. If the ear canal is poorly ventilated, a high-concentration carbon dioxide environment will be created, and the ear piece will not be able to be normally differentiated and grow into a “finger-like†shape. Sub-entity. In the late stage of ear growth, when the temperature is high and the humidity is high, it will cause “flowing earsâ€, so during the earing period, the air in the ear canopy should be maintained and the air should be fresh. Since ventilation is inconsistent with heat preservation and moisturization, it is necessary to perform the ventilation according to temperature and humidity. Low temperature, low humidity, to reduce ventilation; high temperature, high humidity, to increase ventilation; in the continuous rainy days, we must always maintain ventilation, reduce humidity, to prevent the emergence of "flowing." Five, two ears management The hairy auricularia can receive 3~4 è¿ž in succession, 1~2 茬 in quantity, and the ear quality in 3 茬 is worse. After harvesting the first crop, in order to promote the rapid growth of the growth of the second crop of fruiting bodies, management should pay attention to the following aspects: 1. Clean up the ear base. After the first fruiting body is harvested, if the ear has not been decontaminated, when the temperature is high, mildew will appear, resulting in contamination of the bacteria and failure to regenerate. For this purpose, the whole surface of the bag should be cut off during harvesting, and the residual ear base on the hole should be removed with a knife. 2. Control of moisture and bacteria. The postharvest fungus bag should stop spraying water for 3 to 5 days, at the same time strengthen ventilation, and dilute the cover on the shade shed, increase the light, so that the surface moisture shrinks. The mycelium in the bag will continue to absorb nutrients and return from the original reproductive growth to vegetative growth. At this time, the temperature should be controlled at 24°C~26°C to promote the rejuvenation of the bacteria and provide the strong mycelium condition for the second ear. 3. Humidity and lure. After harvesting the hairy agar, the moisture in the culture medium has been consumed. In order to induce the formation of primordium, a small amount of sprayed water must be sprayed with atomized water to remove membrane air and renew the air in the shed every day. At the same time, the use of temperature-stimulating stimuli, alternation between wet and dry, promote the rapid formation of primordia, and differentiation into ear buds, long Into fruiting entities. After harvesting each fruit body, because the water and nutrient contents in the bag are relatively reduced, the number of water sprays and the amount of water sprayed must be increased accordingly, and some of the increased production factors can also be sprayed to increase nutrition and stimulate the ears. Hypertrophy, increase production. Core Flavour Sauce,Flavored Ketchup,Bbq Sauce Flavours,Brown Sauce Flavour Ningxia Eppen Biotec CO.,LTD , https://www.nxeppen.com
