When oyster mushrooms are grown, what are the pests that harm oyster mushrooms?

Miscellaneous mushrooms that harm oyster mushrooms: mainly oyster mushrooms, mucor mold, aspergillus, rhizopus, bacteria, viral diseases, bacterial brown spots, macular disease, etc. Chloroderma is the most serious fungus that invades edible fungi, and the medium suitable for the growth of edible fungi is suitable for the growth of green mold filaments.

Oyster mushrooms are not strictly sterilized in the culture material, the disinfection is not strict during inoculation, and the environmental hygiene is not good when the mushrooms come out, and green mold can be produced. The green fungus is discarded immediately after infiltrating the culture material and the mycelium and mushrooms. Prevention method:

1. The water in the medium is adjusted to 60% to 65%, and excess water is easy to mold. 2. Keep the environment clean and dry, and do not accumulate waste and pollutants.

To maintain the hygiene of the mushroom place, the mushroom warehouse should be kept ventilated, the air humidity should be appropriately reduced, the number of watering should be reduced, and the mushroom peak should be prevented from discharging the mushroom for a long time at high temperature. 3.Pick mushrooms in time, remove residual mushrooms, break roots, remove germs, and remove polluted mushroom sticks.

4. Green fungus net injection of green fungus or Lixin fungus king or mycelium injection. The methods of preventing other diseases and preventing green mold are basically the same, and only drugs can be chosen. In addition, during operation, tools and hands should be strictly disinfected with alcohol or potassium permanganate.

The main pests that harm oyster mushrooms: oyster mushroom mosquitoes (also known as mushroom mosquitoes or mushroom maggots), oyster mushroom mosquitoes, fecal mosquitoes, flea flies, fruit flies, houseflies, moths, and noctuidae They mainly reproduce at the highest peak in autumn and winter 11 and 12 months and spring 3 and 6 months, and the egg period is 5 7 days when the temperature is suitable, and the larval stage is 10 15 days. Prevention method:

1. Remove the surrounding weeds and garbage, and maintain the environmental hygiene around the mushroom warehouse. 2. Remove the waste away from the mushroom barn; 3.Spraying or injection of mushroom Zhongshun, avei bacteria, mushroom cis, insecticide, diquat insects, insecticide, high-efficiency chlorofluorocarbons, etc.

Mites, nematodes, maggots, are mainly practical mycelium and fruiting bodies, very small in size, fast reproduction, serious damage, light yield reduction, heavy harvest, eggs ** in raw materials or culture site is not clean, poor ventilation, humidity caused by egg reproduction.

Mushroom mosquitoes, mushroom flies, jumping insects, thrips, mole crickets, rat women, these pests will have an impact on the growth of oyster mushrooms. Some will bite the bacterium, and some will go directly into the mycelium.

Pleurotus mosquitoes, flea flies, fruit flies, noctuidae and moth-eating pests will greatly harm the production and living environment of oyster mushrooms.

For example, larvae such as mushroom mosquitoes and mushroom flies can bite the fruiting body stipe to the cap into a sponge; Jumping insects, thrips, etc. will enter the folds of the human fruiting body, and it is difficult to remove them even if they are washed with water; Mole crickets and rat women will destroy the covering soil of the mushroom furrow, making it difficult for mushroom buds to occur.

The main insect pests are mosquitoes, nematodes, jumping insects, fungus flies, horseshoe, etc., so it is necessary to carry out timely prevention and control.

I want to buy oyster mushroom sticks and I don't know if ** is sold?

Oyster mushrooms are common mushroom vegetables in our daily life, which are delicious and nutritious, and are deeply loved by people. In the process of oyster mushroom planting, it is inevitable that some diseases will attack, if not timely controlled, it will lead to a serious reduction in the yield of oyster mushroom.

1) In the cultivation process, the environmental conditions and management methods are not appropriate; A phenomenon that causes abnormal physiological activity. We call them physiological diseases.

Long mycelium: The aerial hyphae on the surface of the mycelium are dense, which affects the mushroom production. The main reason for the formation of mycelial wind is high air humidity and poor ventilation. To prevent it, strengthen ventilation and reduce humidity.

Bigfoot mushroom of Oyster mushroom: The fruiting body cap is extremely small, and the stipe is thick and long. This is mainly caused by lack of oxygen and poor ventilation. As long as ventilation is strengthened, pay attention to the light can prevent it.

Oyster mushroom wilting: The growth of mushroom buds or fruiting bodies is stagnant, and gradually shrinks, dries out, dies, and decays. The main reason for the occurrence is insufficient moisture and excessive ventilation. Prevention method, increase the relative humidity of the air, do not dry the material surface, and do not let the wind blow directly on the mushroom buds or fruiting bodies when ventilating.

2) The fruiting body is contaminated with other miscellaneous bacteria, resulting in morbidity or death. We call this an impregnated disease. A common disease of oyster mushrooms is dry bubble disease (brown spot disease), which mainly harms its normal growth.

Symptoms include white villous hyphae on the surface of the fruiting body, brown spots, and atrophied and cracked caps.

Crazy growth of mycelium: the surface layer of mycelium is dense with aerial mycelium, which affects the emergence of mushrooms. The reason for the crazy growth of hyphae is mainly caused by high air humidity and poor ventilation.

Ventilation can be strengthened and humidity can be reduced. Bigfoot mushroom of Oyster mushroom: The fruiting body cap is extremely small, and the stipe is thick and long.

This is mainly caused by lack of oxygen and poor ventilation. As long as ventilation is strengthened, pay attention to the light can prevent it.

1. Crazy growth of mycelium: It refers to the relatively lush growth of aerial mycelium on the surface of the mycelium of Pleurotus oysterus, which affects the situation of mushroom production.

2. Oyster mushroom Bigfoot: This disease is mainly due to the phenomenon that the cap of the fruiting body of Oyster mushroom is very small and the stipe is very thick and long caused by long-term hypoxia and poor ventilation.

Pleurotus oysterus macerate disease has brown spot disease, which is also one of the diseases that have a greater impact on the growth of Pleurotus ostreatus, which will produce a layer of white villous hyphae on the surface of its fruiting body, and then brown spots appear, causing the cap to dry out and shrink. Usually pay attention to the ventilation and cooling of the mushroom shed, and the place where the disease occurs can be sprayed with the corresponding agent**.

Pay attention to environmental hygiene, rinse and brush the walls with 5%-6% alkaline water, sprinkle quicklime on the ground, or spray lime acid to eliminate miscellaneous bacteria. In addition, insecticides are sprayed to eliminate poisonous insects. Closed fumigation and disinfection with formaldehyde, sulfur and other drugs.

Like mushroom maggots, fungus mites, jumping insects, ants, cockroaches, mice, etc., can cause damage to oyster mushrooms. Therefore, it is necessary to do a good job in insect pest prevention according to the characteristics of the insect, so as to reduce losses.

Oyster mushroom is a common edible mushroom for people, which is cheap and nutritious, and consumers have a wide range of options, which can be said to be a kind of civilian and popular edible mushroom. Whether it is home planting or commercial planting, it is relatively easy for growers to get started and master the planting technology, and the cultivation is divided into bag stacking cultivation and shelf cultivation. With the development of technology, there is now also factory cultivation and so on.

They can go their own way, and sometimes they can also join forces and use each other crosswise, in short, no matter how they are cultivated, they are suitable for their own realityThe management of bacteria should be in place, and the cultivation of healthy and vigorous mycelium is an important task. High temperatures, high humidity, and poor ventilation are the banes. Low temperature germination has the highest yield, and do not burn bacteria.

<> the process of building a pile of fermentation requires a large amount of oxygen, and the waste gas produced at the same time should be discharged in time, so it is best to choose the outdoor cement floor, do not pave plastic film, have a certain slope, conducive to drainage, and be close to the water source and cultivation site, temperature is one of the most important factors in the growth and development of oyster mushroom, in the process of growth and development of oyster mushroom, a series of life and aging activities in the cell must be carried out normally at the right temperature. Oyster mushroom is a kind of adaptable wood saprophytic fungus, the ability to decompose cellulose and lignin is particularly strong, so it can use xylose, wheat straw, straw, bagasse, corn cob (stalk), peanut shell, sunflower seed shell, cottonseed shell and even leaves, weeds and other various oyster mushrooms The most commonly used cultivation method is bag cultivation. It is mainly based on bag cultivation and column cultivation, which has high yield, good quality and high efficiency, and the cultivation of oyster mushrooms in bags has many advantages.

Bagged oyster mushrooms are beneficial to control miscellaneous fungi and pests, and the success rate is very long, and it can be fed and produced every rolling day. The highest yield. The raw materials must be fresh, and the comprehensive materials are mainly used to improve the yield and reduce the cost, such as corn cob, bean straw powder, cottonseed husk and other crop scraps.

The water content of ingredients is different for different raw materials.

It may be that the nutrients are not balanced, and there are not enough nutrients, or the temperature is not too high, which causes these conditions.

The reason is the problem of this variety, it is a variety that is not resistant to pests and diseases, and it is particularly prone to diseases, so it must be carefully managed.

Oyster mushrooms have physiological diseases, which may be due to poor environmental conditions for growth, long-term low temperature, insufficient light, poor ventilation, and high carbon dioxide concentration.

I believe that everyone has eaten mushrooms on weekdays, mushrooms are not only delicious and delicate, but also rich in various nutrients required by the human body, such as zinc, iron and other elements, often eating mushrooms is beneficial to people's health, in our country's mushroom cultivation technology is also very mature, we can often see a lot of growers greenhouse mushroom cultivation, greenhouse cultivation mushrooms not only have high yield, good efficiency, and can effectively prevent the impact of natural bad weather and the invasion of pests and diseases.

1. Construction of cultivated houses.

We can make full use of the resources in our hands, such as having ready-made vacant houses, storerooms, basements, etc., we can choose to use them as cultivation houses, and the houses are preferably facing south, which is conducive to mushrooms absorbing sunlight. There should be wells nearby, etc., the area of the cultivated house is generally enough in dozens of square meters, the doors and windows should be combined with thermal insulation and ventilation, and the walls and ground are best to choose to be painted with lime plaster, which is easy to disinfect. After that, the bed frame is set up in the cultivation room, the bed frame is arranged in the north and south, do not lean against the wall, keep about 60-70 cm between the bed frames, the upper and lower layers are 50 cm apart, the lowest layer is 30 cm from the ground, and some wooden boards and straw curtains can be laid on the bed frame.

2. Cultivation methods.

It is best to choose the cultivation time at the end of June, the land should be prepared, and it is best to plant in corn or soybean fields, because corn and soybeans are in full bloom in this season, and the ridge humidity is high, which is suitable for the growth of oyster mushrooms. First of all, after the ditch is cleared, two ridges are cultivated to vacate one ridge as an aisle, we sprinkle a layer of bacteria, then a layer of substrate, and then a layer of bacteria. Finally, step on it with your feet and cover it with about 2 cm of thick soil or mulch.

About a month after sowing, mushrooms can grow in about a week if the weather is good.

3. Harvesting methods.

When oyster mushrooms turn from dark gray to grayish-white, this is the best time to harvest. At this time, the oyster mushrooms are large and delicious, and they can be harvested with a knife when they are harvested. It is best to take the large oyster mushrooms and leave the small ones so that the small ones can be harvested again.

Choose a steel-framed greenhouse or greenhouse that has not cultivated edible mushrooms, has no mold sources on the site, and has good drainage. Before the germination, the site is disinfected and sterilized. In a 200-square-meter greenhouse, 4 iron drums (or iron pots) containing a little flammable shavings are evenly placed, kilograms of sulfur are added to each barrel, and the large fence is sealed and fumigated for 1-2 days after ignition.

The nutritional requirements of pure white oyster mushroom are complete, and the substrate nutrition should be rich, and the formula is: 62% cotton shell, 20% waste cotton, 10% bran, 3% soybean cake, 2% lime, 1% gypsum, 1% sugar, and carbendazim of urea potassium dihydrogen phosphate. Use 20 cm 45 cm low-pressure polyethylene cylinder, each cylinder contains kilograms of dry material, piercing at both ends, atmospheric sterilization, 100 keep for 10 hours, simmer overnight, cooling.

Cool to 30, inoculate while hot, 15-20 bags of original seeds per bottle, and after inoculation, the bag is placed in the culture room for germs. The culture room is sprayed once a week with 3% lysol or 1% bleaching powder to reduce dust and disinfect.

For the first time planting oyster mushrooms, lime water should be used to brush the wall and quicklime should be sprinkled on the ground for disinfection, and the quicklime sprinkled on the ground should be cleaned out the next day; Secondly, the selection of materials and ingredients is also very important, to choose clean raw materials, and do a good job of disinfection, where cellulose rich corn stalks, corn hearts, wheat straw, straw and a variety of wild grasses can be used as oyster mushroom culture material. Practice has proved that after 2 to 3 months of stacked straw and forage have the best bacterial effect. Note that moldy straw cannot be used to grow oyster mushrooms.

If you use corn stalks or corn hearts, use a guillotine or a haymaker to cut them into pea-sized pellets before use; If you are using forage, cut it into small pieces 2 to 4 cm long.

When planting oyster mushrooms, suitable strains should be selected according to the local climatic conditions at that time. Strengthen the management of oyster mushroomsUnder natural temperature conditions, the management of mushroom emergence period is light, water and aeration. During the mushroom production period, the needs can be met by scattered light, and the mushroom is planted in the mushroom room with insufficient light and slow mushroom emergence, which can be supplemented with electric light to induce mushroom emergence.

Seed selection treatment: seed selection treatment is the basic requirement of the simplest method of oyster mushroom planting, corn cob without mildew should be selected as the material, first put in the sun for about a day, add an appropriate amount of bran, quicklime, compound fertilizer and grammycolin mixed together, and then put it in a sealed environment, and turn it once a day to let it fully ferment.

Oyster mushrooms should be cultivated in greenhouses so that oyster mushrooms can grow better.

Oyster mushroom rust spot is a common disease of oyster mushroom, and the symptoms of oyster mushroom rust spot are rusty brown spots on the cap and stipe of oyster mushroom. And the reason for its occurrence is the high humidity of the environment.
