The latest prevention and control methods of Ganoderma lucidum aspergillosis
Ganoderma lucidum aspergillosis is the most common disease in the planting process of Ganoderma lucidum, which is caused by Aspergillus fungi. Aspergillus fungi are Aspergillus fungi of Aspergillus flavus and Aspergillus Niger. Let's take a look at the prevention and control of Aspergillus lucidum.
Symptoms of aspergillosis caused by Ganoderma lucidum
After the planting substrate of Ganoderma lucidum was contaminated by Aspergillus flavus, the colony was yellow to yellowish green, Aspergillus Niger was black, grew and spread quickly, absorbed nutrients and water. Aflatoxin secreted by Aspergillus flavus is a strong carcinogen. Aspergillus Niger and Aspergillus fumigatus produce high concentrations of spores that invade the lungs and are easy to produce aspergillosis or "mushroom worker lung disease".
Incidence regularity of aspergillosis of Ganoderma lucidum
The main results are as follows: 1. The route of transmission: Aspergillus widely exists in soil, air and decaying organic matter, and conidia spread by air flow.
2. Occurrence conditions: Aspergillus mainly uses starch and has the ability to decompose cellulose. Bamboo culture bed frame is easy to be produced under the condition of high humidity and poor ventilation. The pH suitable for Aspergillus growth is nearly neutral. It can adapt to a wide range of temperature. The optimum growth temperature of Aspergillus Niger is 20: 30 ℃, Aspergillus flavus is 25: 30 ℃, and can survive for 30 minutes in 45 ℃.
Prevention and treatment of aspergillosis of Ganoderma lucidum
1. Do a good job in the sanitary work of training rooms and cultivation grounds to put an end to pollution sources.
2. The culture medium is strictly sterilized, and sawdust and straw should be stacked or sterilized after exposure to the sun.
3. Adding 1 × 10-6 Shibao or 5 × 10-6 carbendazim can inhibit the growth of Aspergillus flavus and black mold.
