Mushroom soil fertilization can increase yield.

To make mushrooms yield well, proper topdressing is necessary. According to the practice of mushroom farmers in many places for several years, it is proved that the following nine soil fertilization methods will have a good yield increase effect. Please choose them in practice.

Mushroom soup. cleaning mushroom feet and broken mushrooms after harvesting and processing, cutting into thin slices, adding 1- 1.5 kg of water to each kg of material, boiling for 15 minutes, diluting the filtered juice with water to 10- 15 kg, spraying mushroom fungus bed of 30- 40 square meters. When used at fruiting peak, it can make fruiting body plump and prolong fruiting peak.

Manure. After sun-drying pig manure and cow dung, they are crushed, pre-soaked and piled with lime solution for 15 days, then mixed with 5% of manure and a small amount of plant ash, cleaned the bed surface during fruiting, removed the old roots, and sprinkled on the bed surface by hand, which can increase production and income.

Cow dung and urine. Take fresh cow dung urine, boil it until the foam disappears, dilute it with water 7- 8 times, spray it once every 2- 3 days, and spray it to wet the bed surface. If there are small mushrooms on the bed surface, spray them again with water to promote the growth of small mushrooms.

Plant ash spray. With plant ash 25 kg, 50 kg of water soaked, filtered spray hit, can prevent mushrooms red.

Spraying fertilizer. 0.1%--0.2% urea solution is sprayed every 2--3 days to wet the bed surface. For the fruit body of the middle and late mushroom, it has the effect of increasing fertilizer and thickening. It can also be used to dissolve 0.5 kg of calcium superphosphate in 15 kg of water and take the filtered juice. Then add 50 g of ammonium bicarbonate and spray it on the bed surface. It can make the mushroom body plump and increase the yield by 15%--20%.

Salt water spray. With salt 0.5 kg, add water 50 kg, spray in the peak of mushroom, can make mushroom body white.

Spraying soy milk. Take soybean 2 kg, add water to soak soft, grind into slurry, filter residue, add 80 kg water, spray mushroom bed 80--100 square meters, can promote small mushroom growth thick, white.

Spraying glucose water. Spray with 1 kg of glucose powder and 100 kg of water.

Spray carrot juice. Chop 10kg carrot, add 15kg water, boil for 15 minutes, filter juice, add 40 times water, spray 300- 400 square meters of bacteria bed, can increase mushroom yield by 10%--15%.
