Cultivation techniques of Lentinus edodes in summer

Lentinus edodes fresh products in summer have always been a blank in the edible mushroom market. with the development of science and technology, high temperature strains have entered production in recent years. The author advocates the use of water temperature air conditioning to produce mushrooms, using medium and wide temperature strains, which makes the market price of products rise sharply. The main measures are:

Facilities or equipment requirements cultivation facilities: common edible fungus greenhouse, after the completion of spring production, timely cleaning, cleaning out the original bag, cleaning inside the shed, inspection and repair of greenhouse film, spraying appropriate amount of drugs such as all diseases without a trace to be sterilized. Then, pour fresh water into the shed, wait for the water to seep, spread lime powder in the shed, and then move the bacterial bag to the shelf. Cooling equipment: the water temperature air conditioner can not only be used for cooling production in summer, but also can be used for heating and cultivation in winter. In the experiment of out-of-season Lentinus edodes cultivation in summer of 2006, the temperature of mushroom shed was reduced to 20 ℃ and 25 min, and the application effect was very good.

Second, the basic formula for making bacterial bags: sawdust 1800 kg, wheat bran 200g dry g, calcium superphosphate 20kg, urea 3kg, lime powder 20kg, gypsum powder 10kg, Lentinus edodes special additive 1kg. Routine bagging, sterilization, inoculation and sterilization management.

Third, the color of the bacterial bag can be changed after all the bacteria have been sterilized, the white bacterial bag "well" font code can be high, and covered with plastic film, grass cloak, etc., to make it warm up at the same time, by adjusting the coverage of grass and plastic film and uncovering at night, on the one hand, it promotes the white mycelium on the surface of the bacterial bag to lodge, and on the other hand, it increases the temperature difference of the bacterial bag and urges it to change color as soon as possible. In order to increase the temperature difference and remove the pigment secreted from the bacterial stick, the color conversion management of the bacterial stick after taking off the bag should be washed with water, and other management should be the same as above.

Fourth, adjust the temperature and promote the bud to complete the color conversion of the bacterial bag, after punching and replenishing water and other treatment, can be moved into the shed, an interval of about 5 cm single layer discharge, through the water temperature air conditioning for cooling treatment, 1 Mel 2 days later, and then carry out high temperature stimulation, with the stimulation of water and light in the shed, a small mushroom bud will appear in about a week. After that, keep regular use of water and minimize the humidity difference to ensure that mushroom buds continue to appear. The basic management indicators at this stage are: the temperature is kept between 20 ℃ and 25 lux, and the air humidity is between 75% and 95%. Because the mushroom cover is thicker and adapts to a large humidity difference, there is no need to worry that excessive humidity difference will lead to death; by adjusting the cover of the roof, the light intensity in the shed can be kept at 300 ~ 1200 lux; appropriate ventilation to keep the fresh air in the shed.

Fifth, the mushroom management to the Lentinus edodes bag plastic film is thicker, its mushroom bud can not break the bag by itself, so it is necessary to cut the plastic film manually. The method is: in the place where the mushroom bud occurs, cut the plastic film with a small blade, be careful not to hurt the mushroom bud, if the management is careful, you can cut a round opening along the mushroom bud, so that deformed mushrooms can be avoided to the maximum extent. After the young bud reached out, it entered the stage of mushroom management. This stage should be maintained: a temperature of 20 ℃, a humidity of 75% Mel 95%, light of about 500 Mel 1000 lux and proper ventilation. When the diameter of the cap is more than 2 cm, the mushroom can be directly sprayed with three-dimensional nutritional essence of edible fungi. When the edge of the lid of Lentinus edodes is still rolling down (the edge of the gong), but there is a tendency to unfold, it should be harvested in time. To a certain extent, the temperature in the greenhouse and foliar fertilization at this stage will determine the yield and quality of Lentinus edodes. The management of mushroom production with bacterial stick is more convenient than that with bacterial bag, but because the bacterial stick is exposed, there is more water loss during mushroom emergence, so the humidity should be increased, and the treatment of soaking bacterial stick or water injection should be given. The tide of Lentinus edodes is more obvious, and when the mushroom is harvested, the water loss of the mushroom bag is more serious, so it is necessary to replenish water and raise bacteria before it can be managed and harvested. The common method of replenishing water is to use the original ditch, canal, pit or dig a soil pit, spread plastic film inside, discharge the bacterial bag, when it is about 20 centimeters away from the upper edge, spread a plastic film to make it concave, fill it with water in the concave type, and form a certain pressure, then fill the pit of the bacterial bag with water, after filling up, maintain for 24 hours, you can drain water, put the bacterial bag on the shelf of mushroom production, and refer to the aforementioned management.
