First, control the temperature The growth range of hairy ears is 16°C-35°C, and the optimum growth temperature is 24°C-28°C. In this temperature range, the higher the temperature, the faster the ear growth, and the temperature lower than 18°C. The growth of the tablets is slow, and when the temperature exceeds 35°C, the growth of the tabs is inhibited. 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 Hairy ear ear growth and development stage, the need for air relative humidity of 85% -95%, can be used to maintain the relative humidity of the air by spraying water, spray water can be used directly to the ear and space spray pipe, but mainly to the space and Water on the ground. The water spray should be based on the climate and the growth conditions of the ears. When the weather is sunny, the temperature is high, and the ears are large, the amount of water sprayed should be large. The water spray should be 3-4 times a day; cloudy days, ear hours, less water spray 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, we must do a good job of alternating wet and dry management. If we are exposed to high temperature and high humidity for a long period of time, we can easily experience “flowing earsâ€. After each water spray, ventilation is combined with ventilation to disperse excess water from the hair ear ear. 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 In the process of growth and development of the ear, hair fungus absorbs a large amount of oxygen and emits carbon dioxide. If the ear canal is poorly ventilated, it will result in a high concentration of carbon dioxide environment. The ear can not be formed normally and grow into a finger-like shape. The child 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 under normal circumstances, with 1-2 茬 多 è´¨ è´¨ è´¨ è´¨ è´¨ è´¨ è´¨ è´¨ , , , , , , , 。 。. 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 be sprayed for 3-5 days, at the same time, the ventilation should be strengthened, and the covering on the shade shed should be thinned to increase the light and shrink the surface moisture. The hyphae in the bag will continue to absorb nutrients and return to vegetative growth from the original reproductive growth. At this time, the temperature should be controlled at 24°C-26°C to promote the rejuvenation of the bacteria and provide strong mycelial conditions 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, the water and nutrient contents in the bag are relatively reduced. Therefore, 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 promote hair growth. Fungus ear hypertrophy, increase production.
