In the bag or section of wood inoculation is infected with green mold, the onset of the initial culture material or the substrate appeared white mycelium, and the mycelium of the fungus is extremely similar to the mycelium, the mycelium grows very fast, a few days after the formation of conidia can be formed, once spores begin to vigorously form and mature, the colonies will become green powdery, which is also the origin of its name.
Prevention methods: pay attention to the cultivation site and the surrounding environmental hygiene, keep the planting site well ventilated and easy to drain, in and out of the culture room is to disinfect the treatment to prevent the disease from being brought in, in the fungus out of the ear every day after the spraying of 1% lime water, in the disease is still for the full onset of the disease, but also can be used to scrub the disease with a high concentration of lime water out of the disease can be inhibited growth.
2, flow ear
Flow ear occurs in the late ear, in the ear piece is almost mature or already mature, the ear piece began to soften or even rot. It is a symptom of the rupture of the cells of the fungus, in the ear piece maturity, will continue to produce spores, a large number of consumption of the substrate nutrients, resulting in the aging of the substrate, this time, if in a high temperature and high humidity environment is prone to the phenomenon of ear flow. In addition, bacterial infections and insect pests can also lead to fungus.
Prevention methods: strengthen management, pay attention to ventilation and light conditions, timely harvest, in the fungus is ripe or already ripe in time to harvest, you can avoid this problem, the available hygromycin solution spray to prevent ear
3, thrips
Thrips, also known as the creeping rodent, which is the adult size of the body after the less, black appearance, in the light of the environment is not easy to find, it is not easy to find the larvae of the insects began to The larvae start to harm the fungus, invade the ear pieces and start to suck the sap, causing the ear pieces to shrivel up, which reduces the yield and causes the ear to flow, leading to the extinction of the harvest.
Prevention methods: pay attention to environmental hygiene, clean up fertilizers and contaminated bags in a timely manner, sprinkle lime powder on the ground once to eliminate the source of overwintering insects, and install door and window screens in the fungus room to prevent insects from entering. When pests occur, we can use sugar and vinegar solution to trap and kill, or use trichlorfon liquid spray to exterminate the pests.
I, the main pest control
Mainly mosquitoes, flies, mites, slugs, nematodes, flea beetles and so on.
1, prevent adult insects from entering. Fungus room installed screen window screen door, the peak of adult insects every 3?5 days in the window door screen with 80% of dichlorvos 500 times liquid or with 50% wettable trichlorfon 1 catty, plus 1000-1500 pounds of water spraying.
2, improve environmental health, eliminate overwintering insect sources. Timely disposal of waste materials and contaminated bags, the complete elimination of garbage and other easily corruptible substances inside and around the shed, the ground to spread a layer of lime.
3, trapping. (1) sugar and vinegar solution (white wine 0.5 parts, 2 parts of water, 3 parts of brown sugar, 4 parts of vinegar) into the porcelain plate, and then a few drops of dichlorvos or trichlorfon, placed in the germination room or cultivation room to trap adult insects. (2) use black light or ordinary incandescent lamp to trap adult insects under the lamp set a plate of waste ear or fertilizer leachate, plus a few drops of dichlorvos trapping.
4, slugs. Can be manually trapped and killed can also be used to snail net mixed into crushed grass, in the evening sprinkled near the cultivation site for trapping; with mushroom haha spray can kill nematodes, the concentration of 600 mg / liter; planting culture room occurs jumping bugs, can be sprayed with 0.1% of the fischer's tongue essence or pyrethroids (1:500-2000).
5, in the peak of adult insects with 80% dichlorvos 800 times liquid every 3-5 days on the ear shed (room) to spray.
Second, the main disease prevention and control
The main diseases of fungus include various molds and "ear flow".
1, for the "flow ear", in addition to pesticide prevention, can try 25 units / ml concentration of gentamycin (or hygromycin) solution, or 500 times the solution of zinc dicenta (or refund of fungus) solution spray.
2, before inoculation, the inoculation box (room), inoculation bags, strains, inoculation tools, sealing plugs, disinfectant drugs, etc., per cubic meter with formaldehyde 10 ml and potassium permanganate 5 grams or with the protection of mushrooms king 3-4 grams per cubic meter fumigation disinfection.
3, culture materials should be timely sterilized after bagging, atmospheric sterilization 100 ℃ to start counting, to maintain 8-12 hours to ensure complete sterilization.
4, frequent inspection, found that the infected strains and cultivation bags timely culling, at the same time to timely ventilation and drying, control room temperature at 20-22 ℃.
5, the fungus bag out of the ear during the occurrence of a small area of mold, you can pull open the plastic bag with stray mold parts, in the stray parts of the fungus sprinkled with fungus kill powder or 0.2% potassium permanganate or polymyxin solution spray disinfection.
6, clean up the residual ear in time, and spray 0.2% polymyxin or bleach solution in its site.
7, in the production process to use all the clean water; mixing, appropriate to raise the PH value, add 2% -3% of quicklime.
