How to prevent and treat morel fungus diseases
Due to the impact of various pests such as collembola and fungus mosquitoes, the cultivation process, yield and quality of morel mushrooms are difficult to be guaranteed. For this reason, comprehensive control and management methods such as exposure to the field, light trapping and killing insects, and drug-assisted prevention and control should be adopted to strictly control the planting process of morels. The principle of "prevention first and drug prevention as supplement" should be adhered to for comprehensive management.
In the cultivation of morels, great attention should be paid to the prevention and control of diseases and insect pests. As far as possible, select strains with good varieties, strong hyphae, and fewer passages, and control the selection criteria for the age of the strains to no more than 40 days. It is best to arrange the planting time from November to December every year to control climate factors and keep the oxygen content of the air not lower than the survival standard of morels. Add an appropriate amount of mushroom-preserving drugs to the culture medium of morels, and spray the drugs appropriately to kill viruses and insects, so as to keep the planting environment clean and hygienic.
In order to do a good job of prevention, water should be sprayed regularly after morels are planted to keep the air humidity and soil humidity in the best state, maintain the content of probiotics in the soil, and achieve the purpose of inhibiting the growth of germs. Attention should be paid to the correct use of drug sterilization methods, and the drug-assisted sterilization work should be divided into two times according to the strains and the actual conditions of the planting place. The first time is carried out in the medium, and the second time, the sterilizing drug can be sprayed around and on the surface of the medium, so as to achieve the effect of sterilization and disinfection, and also provide a strong guarantee for the smooth progress of the morel planting work.
