Fungus and insect pest control.
The prevention and control measures of the parasols: the fresh culture medium should be selected as far as possible, 2 days prior to use, or the raw material in limewater.When the amount of nitrogen in the culture medium is controlled, the amount of wheat bran or rice bran should not exceed 5%, and livestock manure should be 3%.No matter what kind of material is cultivated, the best secondary fermentation can greatly reduce the pollution of ghost umbrella.The water content of the culture medium is controlled at 70%, so as to ensure high quality stacking.At the same time, when the medium is mixed, the pH value of the adjusting medium is about 10.
Trichoderma viride prevention measures: trichoderma viride range in 4 ℃ ~ 42 ℃ growth, spore germination and high humidity environment, violations of the straw mushroom culture medium, the early white cotton flocculent, late to green, strain if harm by trichoderma viride, must be discarded, even mild strains of disease should abandon.Musty has not had the ideal radical medicine, the commonly used bactericidal drug, to the wood mold is only to suppress, but cannot kill, increase the dosage, can only simultaneously kill the wood mould and the mushroom mycelium.Therefore, creating an ecological environment suitable for the growth of mushroom mycelia, which is not conducive to the reproduction of wood fungi, is the fundamental measure to control the harm.In the event of trichoderma viride, immediately ventilation cooling, to restrain the expansion of trichoderma viride, substrates under hair bacteria phase after feeling ill, can adopt the method of injecting liquid inhibit trichoderma viride expansion, commonly used solution with 5% 2% phenol and formaldehyde, and zero times of 50% carbendazim, 75% of mildothane, pH value of 10 limewater, moreover, put white pollution in surface, control effect is very good also.
Mushroom mite of prevention and cure: give priority to in order to prevent, mushroom room as far as possible away from the warehouse, feed, livestock shed, etc., cultivation of raw materials for secondary fermentation, serious when, mushroom house in front of the back of material to use dichlorvos, acaricidal, alcohol and acaricide 500 times liquid spray or fumigation for 24 hours, once found a small flat in or elliptic, white or yellow, how long the root hair of mushroom mite, immediately use the following method to kill it: fumigation acaricidal: dip in with cotton ball dichlorvos, on bedstead base surface, then use plastic sheets to cover the bed surface, use drug volatile fumigation kill mites.Spray insecticide: 1, 500 times liquid or 500 times chlorite.
Control method of mushroom fly: set gutter around the mushroom farm, eliminate the water, and use 0 regularly.
