Why does hericium Erinaceus grow malformed?

Why does hericium Erinaceus grow malformed? Is there any way to prevent and cure it? Also asked experienced netizens to help introduce that many farmers found hericium Erinaceus malformations in the process of cultivating hericium Erinaceus, so the farming network sorted out the causes and prevention methods of hericium Erinaceus deformities, which are listed in detail below for netizens' reference. The reason for the occurrence of bald and unarmed Pleurotus ostreatus: this kind of deformity is mainly caused by high temperature and low humidity, and the evaporation of fruiting body is often too large at 25 ℃, but the humidity does not keep up in time, resulting in the formation of Pleurotus ostreatus without burrs. Prevention of baldness without thorns: pay attention to temperature control and moisturizing. When the temperature exceeds 25 ℃, the mushroom bed cultivation in the field should uncover the film in the morning and evening to ventilate, open both ends of the film during the day to make it breathable; border and ditch irrigation to reduce the ground temperature, space spraying of atomized water to increase humidity, keep above 90%, and thicken the shade cover, reduce the penetration of sunlight and reduce water evaporation. The reason for the formation of coral-clustered hericium Erinaceus: the base of the coral-clustered mushroom is clustered for many times, which is shaped like coral, and it is obvious that there is a rhizomatous fungal cord connected to the culture medium. Some of the seed bodies die in the mushroom stage, and some can continue to grow and develop. The top of the branchlet continues to expand to form a number of small entities in the state of hericium Erinaceus. The formation of this kind of mushroom is mainly due to the excessive concentration of carbon dioxide, stimulating the continuous differentiation of the stalk, inhibiting the development of the center, resulting in the formation of irregular coral, and some because the culture material contains aromatic compounds or other bactericidal substances. to inhibit or abnormally stimulate the growth and development of hyphae. Some growers put one-sided emphasis on heat preservation and moisturizing, ignoring ventilation and ventilation, which forces the fruit body to develop abnormally under the condition of saturated humidity and still air. Coral cluster-shaped hericium Erinaceus prevention methods: 1. Strengthen ventilation in the mushroom farm to eliminate the occurrence of abnormal young mushrooms, especially indoor cultivation, pay more attention to ventilation and improve environmental conditions. 2. 2. When selecting culture materials, attention should be paid to removing trees with germicidal effect, such as fir, pine, camphor, poplar, locust and so on. 3. The coral-like fruiting body has been formed, which is immediately scraped off together with the surface culture material when young, and then cultured again to produce mushrooms normally. The reason for the formation of hericium Erinaceus with abnormal mushroom color is that the mushroom body is yellow, the spines are short and thick, some fruiting bodies turn red or the young mushrooms are pink from the beginning to maturity, and the mushroom body tastes bitter. The main factors for the formation of this kind of mushrooms are low temperature, which is often cultivated in autumn and winter, the temperature drops suddenly, the growth stage of fruiting body is less than 10 ℃, the mushroom body turns red, and the color deepens with the decrease of air temperature. When indoor cultivation is ventilated, the fruiting body is stimulated by direct current wind, and the mushroom body is yellow. Mushrooms with discoloration should be treated according to their etiology and symptoms. If it is caused by low temperature, it is necessary to take into account that the local temperature is not lower than 14 ℃ about 25 days after inoculation, and the best inoculation period can be calculated forward to avoid the damage caused by low temperature. Prevention methods of hericium Erinaceus with abnormal mushroom color: field planting can seal the film, ventilate when the temperature is high at noon, and dilute the cover to attract light to increase the temperature; indoor cultivation to avoid the wind blowing directly when the mushroom is ventilated, or cover the mushroom bag near the window with wet gauze. The production method of hericium Erinaceus cultivation of hericium Erinaceus can produce high yield
