How to grow Pleurotus ostreatus cultivation techniques and matters needing attention

The nutrition of Pleurotus ostreatus is very rich, the taste is very delicious, from birth to the present can not be artificially cultivated, it is the "gift" of nature to human beings. Then everyone will have questions about how to grow Pleurotus ostreatus, what matters need to be paid attention to and what technology is needed to grow Pleurotus ostreatus. This is what everyone is concerned about. Then let's take a look at it with the editor.

How to grow cockfighting mushrooms

1. The mushroom house requires high terrain, open around, clean environment, the house faces south, the top is equipped with a wind tube, and the walls are equipped with north-south symmetrical rectangular skylights and floor windows. The mushroom room requires wind and rain protection, indoor heat preservation and moisturizing, ventilation and light transmission (scattered light), the ground is easy to wash, or it is convenient to tamp the new soil each time. The surrounding walls are disinfected with lime water, and medicament fumigation can be used every time in the room to prevent miscellaneous bacteria infection.

2. Stacking of culture materials

The culture material should be processed by composting and fermentation and decomposed into nutrients that can be absorbed and utilized by mushrooms. In the past, one more fermentation was used, but the fermentation was not complete, the nutrients were not fully decomposed, and miscellaneous bacteria and insect pests still existed. In order to solve this problem, secondary fermentation (post-fermentation) technology has been developed in recent years.

3. Sowing and covering soil

Sowing can begin when the feed temperature drops below 28 ℃. The culture material is arranged into a flat surface, with a thickness of 12-15 cm, hole sowing, row spacing of about 9 × 9 cm, and about 1 square meter of bacteria per bottle (750 ml). If you want to spread bacteria quickly, you can sow more. Attention should be paid to moisturizing after sowing. When the mycelium begins to germinate, it is necessary to gradually strengthen ventilation, promote the mycelium to grow into the material, and control the growth of miscellaneous bacteria (which can be dug out when found). The mushroom bed should be covered with fine mud masses, and the mushroom fruiting body will form and grow normally. Can be used sun-dried vegetable garden soil, beans and other fertilizer soil sifted, large mud mass about the size of pigeon eggs, small mud mass about the size of peanut kernel. When the mycelium has covered the surface and has gone deep into most of the culture material, cover the coarse soil first (about 2.4 cm thick, water content 20%), and then cover the fine soil (about 1.2 cm, slightly dry).

4. Water management

The moisture management of mushrooms should be done less and frequently. The culture material and the overlying soil layer are basically wet on the bottom, wet on the inside and dry on the outside. The temperature is kept at 10-18 ℃, which is the most suitable for solid formation and growth. It is found that when there are small buds on the thick and thin soil layer, mushroom water should be sprayed. When the fruiting body develops to the size of beans, more water can be sprayed to facilitate the development of mushrooms. During the period of mushroom emergence, the air humidity is maintained at 80-90%. After picking three batches of autumn mushrooms, the temperature drops, 0.2% urea or ammonium sulfate can be used, mature human feces and urine, livestock urine or 1% glucose topdressing. After the beginning of winter, strengthen the management, but also try to increase the room temperature of the mushroom room to continue to produce mushrooms. Spring mushroom production starts about March, the management needs to keep warm and moisturize, spray water at the right time, and spray topdressing after each batch of mushroom is picked, before the next batch of mushroom buds are formed.

Planting techniques and matters needing attention of Pleurotus ostreatus

1. Pre-wetting should be sufficient: straw should be fully soaked to facilitate fermentation. Inadequately soaked straw needs a lot of water when it is turned over. If the water can not be replenished before the second turn, it will be difficult to make up in the future, which will affect the growth of mycelium.

2. Turn the pile evenly: when turning the pile, you should put the raw meal in the middle and the clinker on both sides; put both ends in the middle and put the two ends in the middle. If you do not follow this principle when turning the pile, it will lead to uneven fermentation of the culture material and can not achieve the purpose of turning the pile.

3. Soil collection should meet the requirements: some farmers cover the soil with untreated vegetable garden soil, and some even add undermature cow dung. This kind of soil often carries a large number of bacteria and eggs, which is easy to cause a variety of diseases and cause losses to mushroom farmers.

4. Do not add urea when covering soil: new farmers habitually equate planting mushrooms with other crops, adding urea when covering soil, resulting in excessive ammonia smell and mycelium death.

5. Do not spray "closing water": spraying "closing water" at high temperature in the early stage of mushroom planting will cause high humidity environment, causing mycelium, fungus quilt and mushroom death, etc., while spraying "closing water" in the later stage will easily lead to mycelium degradation and premature senescence.

6. disease prevention should be timely: due to the lack of basic knowledge of identification and prevention of diseases and insect pests, some farmers often begin to control diseases and insect pests only when they are serious, so that they miss the best period of prevention and control, resulting in a serious reduction in mushroom production.

How to harvest Pleurotus ostreatus

In principle, the chicken shredded mushroom is harvested as tender as possible, that is, it is better to have the inside at an angle of 45 degrees between the edge of the umbrella and the stalk of the mushroom, while the lowest standard is before the edge of the umbrella is straight, such as the umbrella is straight or even turned over, it is too old and the taste is poor. In the days after a thunderstorm, it is best to go to the place where the mushroom may be harvested every morning. For example, after noon, the mushroom body will rot quickly due to the high temperature.

How to store Pleurotus ostreatus after harvest

For the storage of chicken shredded mushrooms, after the chicken shredded mushrooms are harvested, the roots are removed one by one, and the soil at the base of the mushroom stalk is washed, then wrapped in paper, put into a plastic bag or Tupperware fresh-keeping box, and placed in a 12-℃ repository, it can be kept fresh for more than a week. Chicken shredded mushrooms stored below 10 ℃ will gradually be frostbitten and affect their taste according to the temperature. For example, if the temperature is above 14 ℃, it will gradually accelerate decay according to the rise of temperature, especially when it reaches more than 30 ℃, it will generally cause the chicken shredded mushrooms to rot within one day.

In the case of modern artificial culture technology is so developed, Pleurotus ostreatus can not be artificially cultured, everyone should know how to grow through the above problems, the growth of Pleurotus ostreatus is extremely harsh on environmental conditions, growing in high-temperature and high-humidity jungle. And the culture benefit of cockfight mushroom is very high.
