Bag material Lentinus edodes Why not produce mushrooms?

Bag material Lentinus edodes Why not produce mushrooms? What are the main factors causing it? Is there any netizen to help guide the bag material cultivation of shiitake mushrooms if the operation is improper, which leads to the delay of mushroom production? the farming network has sorted out several factors and solutions of bag material shiitake mushroom, which are listed in detail below for netizens' reference. The reason for not producing mushrooms: first, the selected varieties are not suitable: cultivating Lentinus edodes in spring, making bags in early spring, producing mushrooms in autumn, winter and spring, we should choose medium or low temperature, late-maturing varieties, such as 939, Weixiang No.1 and so on. For out-of-season cultivation of Lentinus edodes, making bags in late winter or early spring and producing mushrooms in late spring, summer and autumn, it is appropriate to choose medium or high temperature and early maturity varieties, such as Shenxiang 10, Shenxiang 6, 931, Wuxiang 1 and so on. If the late-maturing varieties are selected in off-season cultivation, the mycelium can not reach physiological maturity until 3-4 months after inoculation. if the fungus tube is intact, it can pass the summer safely, and the mushrooms will not produce in late spring and summer of that year, but will not produce mushrooms until autumn, winter and spring of the following year. Similarly, if the medium-and high-temperature and early-maturing varieties are selected for cultivation in spring, the bacteria will occur 60-70 days after inoculation, and when the temperature rises, the management of mushroom production should be carried out in accordance with the out-of-season cultivation technique. the nutrients of bacterial sticks are almost exhausted in late winter and early spring, and the yield decreases sharply. There is no production significance. Solution: suitable varieties and corresponding cultivation techniques should be selected according to local climatic conditions and cultivation season. Second, the lack of nutrients in the bag material: 1. The selection of sawdust is unqualified: the sawdust of broad-leaved forest such as branches of fruit trees is rotten and deteriorated, resulting in insufficient effective nutrition for the normal growth and development of Lentinus edodes and even depletion. The selected coniferous tree shavings such as pine, fir, camphor and cypress are directly used without treatment, and the alkenes contained in them can inhibit or even kill the mycelium of Lentinus edodes, resulting in mycelium nutrition deficiency and frustration of mushroom production. Solution: choose fruit trees, oak trees, birches and other Rosaceae, Fagaceae, Betulaceae broad-leaved trees sawdust is ideal, the sawdust of this kind of trees is fresh, dry, pest-free, no mildew. 2. The management of bag material Lentinus edodes is unreasonable: it is mainly manifested in three periods of time: bag culture, summer culture and intermittent culture. Solving measures: through piercing, heating, thinning pile, ventilation, shading and other measures to control bacteria, the ambient temperature of bacteria stick in summer is 18-25 ℃. After the end of a crop of mushrooms, the intermittent culture time is generally 7-15 days, or even longer, in order to rejuvenate the hyphae and accumulate more nutrients. Third, the management of color conversion is not in place: some rods are affected by strong light, too dry air or too many times of turning, which often change color too deep, forming a thicker thyroid skin, resulting in difficulties in mushroom production. Solution: during the color conversion period, the temperature of the mushroom shed was maintained at 18-22 ℃, the relative humidity was 55-75%, and scattered light was maintained. When the stick with too thick skin comes out of mushroom, it should be soaked in water and covered with film to increase the temperature, and then stimulate the emergence of mushroom. The reason for not producing mushroom is fourth, the mycelium grows improperly: after the mycelium is inoculated on the culture medium, the fruiting body can be formed only when the mycelium is physiologically mature. The length of bacterial age is restricted by species and environmental conditions, and temperature is the key to affect the physiological maturity of mycelium. For medium and low temperature varieties, the suitable temperature for mycelium growth is 20-25 ℃. If the mycelium is below 20 ℃ for a long time, especially below 10 ℃, although the mycelium is cultured for a long time, the accumulated temperature is not enough and the mycelium is immature, so it will not produce mushrooms. Solution: continue to cultivate the bacterial bag under the condition of 20-25 ℃, or pile up the bacterial tube and cover the film to increase the stacking temperature and promote the development of mycelium. Fifth, the temperature of the mushroom shed is not adjusted properly: the temperature of the mushroom shed is lower than 8 ℃ in winter or early spring, which is determined by the physiological characteristics of Lentinus edodes. Solution: raise the temperature by means of flue, stove, heating, drying film in mushroom shed, etc., so that the temperature of mushroom shed can reach 8-25 ℃. The reason for not producing mushroom sixth, the quality of strain is poor: solving measures: the production of bacteria should be tested and demonstrated, and the number of passages should be strictly controlled, generally within 3 times. The strain farm should have the basic facilities for producing bacteria and the conditions for preserving them. When purchasing bacteria, growers should, under the guidance of the technical department, purchase from scientific research institutions with good reputation and strong technical force, ask for the name and characteristics of the varieties, and select age-appropriate bacteria that grow neatly and healthily, without the need for degraded and aging strains.
