First, the temperature of the high-temperature burning bacteria sowing period is high, the culture material is too thick, and the temperature of the material is not consolidating after fermentation. The temperature in the culture material is higher than 30°C.
Prevention and control methods Mushroom sowing period to avoid the high temperature period, sowing temperature should be consolidating below 25 °C, sowing hyphae after the discovery of atrophy due to high temperature, should be re-turning ventilation, and then adjust the humidity of the culture material, re-seeding.
Second, there is a large amount of nitrogen fertilizer added to the heap when there is ammonia in the material, or the nitrogen fertilizer is added too late (it is only added when the latter is turned). After the bacteria seeds are sown, ammonia is present in the culture material.
Prevention and control methods When adding urea and other chemical fertilizers to culture materials, one must be added at the time of building the heap, and the second is to moderate the amount. Ammonia gas was found in the material, doors and windows were opened in time, and 2% formaldehyde solution was sprayed to turn over the material. After the ammonia smell was absent, the seeds were replanted.
Third, the culture material is too dry when the cultivation of dry material, if the climate is monotonous, hyphae after eating germination growth is slow, weak and atrophy.
Control methods can be used to cover the surface of a layer of wet straw (infiltrated with 0.5% lime water), can rejuvenate the hyphae to eat. Seeding met monotonous weather and opened doors and windows three days after sowing. It is better to use layer broadcast and cover seeding.
IV. Excessive water content The culture material has too much water content. After covering the soil, it also encounters high temperatures, or sprays heavy water at high temperatures, but there is no timely ventilation, so that the mycelium shrinks due to lack of oxygen supply and vitality.
The control method should pay attention to the control of moisture when stacking materials. If the moisture content of the material is found to be too high during turning, it should be spread out and then dried. The water content of the fermented material should be 60-65%. After the late spray heavy water caused by the shrinkage of seedlings, ventilation, hyphae can resume growth. The total thickness of the bed cover should not be less than 4-4.5 cm
Fifth, the poor quality of strains purchased varieties of bacteria on the way to heat, decreased mycelium growth; bacteria can not be used in time, strains aging, weak growth potential, after sowing bad environment, will lead to hyphae atrophy.
Control methods Choose the appropriate culture material culture strains, the strains should be thick and strong germination; buy the species to avoid high temperature days; do not use the aging strains sowing.
6. The key insects of insect pests are fleas, which are difficult to see in the early stages and are mainly damaged by hyphae, causing the hyphae to break and shrivel. They can bring pests into the compost and overburden and cause serious damage.
Prevention and control methods Aphid production and culture materials, covering soil, bacteria and other related, it is necessary to carry out comprehensive prevention and control. Do a good job in the post-fermentation culture materials, cover soil to be insecticidal solution, strains in the day before sowing with dichlorvos fumigation and so on. In addition, the mushroom powder can be effectively sprinkled into the material before sowing. Found in the cultivation of earthworms, early control with chemicals.
Mushroom hyphae atrophy prevention
In mushroom cultivation, it is often encountered that the mycelium does not eat, yellow, and shrink after germination, which seriously affects the development of mushroom production. The causes and prevention methods will be introduced as follows:
