Ten ways to increase the yield of Pleurotus ostreatus

I. temperature difference stimulation method

During the formation and development of Pleurotus ostreatus fruiting body, the temperature difference stimulation of 7 to 12 ℃ per day could promote the early emergence of mushroom and the orderly development of fruiting body. The specific methods are as follows: covering the film for heat preservation during the day, opening the film in the sunny evening or in the morning, ventilating and cooling to increase the temperature difference, and combined with high humidity management to induce mushroom production.

2. High humidity stimulation method

First, leave the bacterial bed (or bacterial block) open and dry for 1 / 2 days, and then spray water 2 / 3 times a day for 2 / 3 days, so that the bacterial block slowly absorbs water, so that the water content of the culture medium on the surface of the bacterial block can reach the water drop when it is held by hand. During the period of water spraying, the bacterial bed can be opened for ventilation; after spraying water, use cotton cloth to dry the stagnant water on the culture material surface, cover with thin film for heat preservation, and bud can appear after a few days. To adopt the method of high humidity stimulation, there are two conditions: first, the mycelium must eat through the whole culture medium and reach physiological maturity, which is mainly marked by yellow water spitting, the bacterial membrane and mycelium are slightly yellowish brown, and even individual mushroom buds appear; second, the culture medium must be agglomerated. Can't be loose.

Third, shock bacteria stimulation method

When the culture medium is full of mycelium, extruding, beating and shaking the surface of the culture material with strong elastic wood strips can accelerate the growth of mycelium and the rapid differentiation of fruiting body, thus increasing production. Apply even force when shaking bacteria to prevent damage to the material surface.

Fourth, light induction method

When Pleurotus ostreatus is cultivated indoors, a certain amount of scattered light is needed for fruiting body formation. Pleurotus ostreatus should be infected in the dark after sowing, and the mushroom can be induced by exposure after the hyphae are well developed. When the mushroom house is lack of light, it can be supplemented by electric light, and it also has a better inducing effect, which can accelerate the speed of mushroom production.

5. Spraying plant hormones

Spraying 0.5 × 10-6 × 10-6 1 × 10-6 triacontanol solution once in the bud stage can make the fruiting body fat and the mushroom color white, and generally increase the yield by 10% 15%. Spraying 0.05% ethephon solution once in the mushroom bud stage, young mushroom stage and cover expansion stage, spraying 50 ml per square meter of bed each time, can make the mushroom body strong, and the yield-increasing effect is obvious.

Monosodium glutamate stimulation

Dissolve 50 grams of monosodium glutamate (sodium glutamate), 500 grams of glucose and 100 tablets of vitamin B1 in 50 kilograms of water. After the first tide of mushroom harvest, spray the above solution every 7 days or so, 0.5 kg per square meter of mushroom bed for a total of 3 times, which can significantly increase the yield in the later stage.

The method of spraying plant ash

At the end of each tide mushroom harvest, 5 kg of plant ash is added to every 100 kg of water, soaked, and then its clarifying solution is evenly sprayed on the bed, which can promote the firmness of mushroom production, prevent the mushroom body from becoming red, and the effect of increasing yield is obvious.

VIII. Spraying compound agent method

The compound liquid was prepared with 5 grams of regulator, 20 grams of magnesium sulfate, 10 grams of zinc sulfate, 5 grams of boric acid, 50 grams of vitamin B 1250 grams and 50 grams of urea, and diluted with 50 kilograms of water. it can promote the formation and hypertrophy of fruiting body and increase yield significantly.

The method of applying benevolent fertilizer

Enfei is a new type of highly concentrated organic compound liquid fertilizer, which can accelerate the growth of edible mushroom and rejuvenate the hyphae, and inhibit the growth of miscellaneous bacteria. The application of grace fertilizer on Pleurotus ostreatus can make the mushroom grow 3-4 days earlier, accelerate the change of tide, and harvest 2-3 tide mushrooms more. Usage: after the Pleurotus ostreatus fruit body enters the mulberry stage, spray 0.1% of en fertilizer solution 100 ml per square meter of bed, spray again every 2 days, spray twice, a total of 4 times.

10. Application of rare earth method

The application of rare earth to edible fungi can not only increase the yield, but also improve the quality of edible fungi. After the application of rare earth, the individual size and meat quality of Pleurotus ostreatus increased, and the yield increased significantly. There are two ways to use it: one is to stir. Take 610 grams of agricultural rare earth nitrate or 250 grams of rare earth nutrient solution of "Mushroom" edible fungus for every 100 kilograms of culture material, dilute the solution with slightly acidic water, and spray evenly on the material for the last turning. The other is to spray directly into the bed. When the fruiting body of Pleurotus ostreatus generally grows to the size of soybean grains, it is sprayed on the bed surface combined with replenishing water. The solution is generally prepared with 4 grams of agricultural rare earth nitrate or 250 grams of "mushroom music" every 50 kilograms of water.
