Most edible fungi growers know that the summer is the main harvesting period of black wood fungus, while the mushroom of the segmental wood mushroom is highly consumed after the spring mushrooming. In summer, the mushroom needs to raise the bacteria in time for the autumn mushroom. be prepared. The following is a summary of the technical measures for the management of the wood fungus and mushroom in summer, for your reference.
First, black fungus
In the ear period, the water management method of “dry, wet, wet and dry†should be adopted. If there is continuous sunny day, and there are young ears on the ear, water can be sprayed around noon; the temperature in July and August is too high. To supplement the moisture content of the ear wood, it should be sprayed at night; when the temperature is suitable for the growth and development of the fungus, the water should be sprayed out of the ear, and the heavy water should be sprayed in the early stage of the ear to allow the ear wood to absorb moisture and promote the ear bud. Light spray, fine spray, stop spraying once every 2-3 days, interval 1-2 days; after harvesting one fungus, stop water for 6-7 days, according to mycelial growth and temperature in the ear Whether it is appropriate, and then carry out the next ear and ear management. Spraying water during earing should try to turn over the ear wood as much as possible, so that the ear wood can absorb water evenly and receive light. In case of high temperature and dry weather, it is especially necessary to prevent the ear wood from peeling. The water spray must be carried out at night after the temperature of the ear surface is lowered. Volt (Xiaer) requires the same size to be harvested. Because the temperature is high, it is easy to be infected by insects and bacteria. The harvested fungus should be fine after rain, the ear is dry, and the ear is still wet.
Second, the mushroom management in summer
(1) Renovating the mushroom shed. It is necessary to take corresponding management measures according to the temperature change. In summer, the shade shelter will be built according to the requirements of “seven yin and three yang†to create a suitable shade environment for the bacteria stick to prevent exposure, hydration during drought, temperature and humidity adjustment, and mushroom hyphae. Robust growth and safer summer.
(2) Management of the bacteria stick. Set up the bacteria bar code to build the code pile, and clear the drainage ditch to prevent water accumulation in the mushroom field. 40-60 days before the mushroom in the autumn, the mushroom wood is coded into a "thin #å—å †", covered with agricultural film on rainy days, rainproof, so that the mushroom stick is gradually dried, ready for the autumn mushroom.
(3) Prevention and control of mushroom and mosquito
Agricultural measures
First, thoroughly clean the old mushroom farm, remove the waste mushroom sticks, litter, and burn it in a concentrated manner. The mushroom rods can be transferred to the farm under conditions. The new mushroom farm should be thoroughly cleaned before being used. Second, the new mushroom farm should be far away from the slopes of the forest and the old mushroom farm. Third, the newly harvested mushroom sticks should be brushed with lime water or fired with bark for 2 to 3 minutes to kill the insects. The fourth is to strengthen cultivation management, promote the good development of shiitake mushroom hyphae, and enhance resistance.
2. Physical control
One is to artificially cull larvae. Second, the mosquito pests have strong phototaxis, and can be placed around the mushroom field to place black light or high-pressure insecticidal lamps to trap.
3. Chemical control
(1) Mushroom field. After the mushroom field is cleaned, 4.5% beta-cypermethrin emulsifiable concentrate 1500 times solution or 50% phoxim emulsifiable concentrate 800 times solution or 20% sterilized emulsifiable concentrate 1000 times solution can be used.
(2) Mushroom sticks. For insects with insect pests, they can be immersed or fumigated to disinfestation.
1 Soak: Soak the stick with 2-4 times of 4.5% beta-cypermethrin EC or 1200 times of 20% off-cream emulsifiable concentrate for 2-3 hours. The rod must be completely submerged in the liquid.
2 fumigation: each mu of mushroom wood with 22% dichlorvos fuming agent 0.5 kg closed fumigation 2-3 days.
(3) The use of chemical agents should be carried out in the summer, idle period of the fungus sticks, 30 days before the mushrooming, to prevent contamination of the mushrooms, pay attention to medication safety, and prevent poisoning of humans and animals.
