Detailed Explanation of Traditional Topdressing Techniques for Edible Mushrooms

1. Soak 0.5-1 kg of fresh soybeans, grind into a slurry, filter out the residue and take the juice, dilute with 50 kg of water and spray; this can increase yield by 10%-15%.

2. 40 g of monosodium glutamate + 1 kg of sugar + 100 kg of water, sprayed during the young mushroom stage, has an obvious yield-increasing effect.

3. Boil mushroom roots and broken mushrooms for 10 minutes, dilute the liquid with water, and apply it together with watering (decoction:water = 1:10). 4. Soak 3 kg of plant ash + 50 kg of water, then take the filtrate and spray.

5. Spray after diluting rice-washing water or tofu water.

6. 20% carrot juice. Chop 1.5 kg of fresh carrots, add 8-10 kg of water, boil for 30 minutes, filter out the residue and take the juice, then dilute with 3 times the amount of water.

7. 0.05% yeast powder solution. Add 35 g of pure yeast powder to 50 kg of water, stir well, and spray.

8. 0.5 kg of coarse salt + 100 kg of water, applied during the peak mushroom-producing period, can promote white, plump, and firm mushroom bodies.

9. In the late stage of mushroom production, the pH value of the casing soil layer decreases. Use 1 kg of quicklime + 100 kg of water, stir and take the clear liquid, and spray; repeat once every 6-7 days.

10. Wash and chop bean sprouts and spinach, place them in a high-speed blender, add a small amount of water and blend, then filter through four layers of gauze to obtain the juice, dilute with 500 times the amount of water, and begin spraying 15 days after sowing, using 1500 ml per square meter; this can advance mushroom emergence and increase yield.

11. Magnetized water. Use two magnets, placed 15-20 cm apart with opposite polarities, and let water flow vertically through them to obtain magnetized water. According to experiments, spraying magnetized water causes pinning 2 days earlier than tap water, greatly increases yield, and results in uniform mushroom emergence and thick, plump mushroom bodies.

12. Wheat bran extract. Put wheat bran in a cloth bag, add 20 kg of water for every 2 kg, boil for 15 minutes, then place into 40 kg of clean water and squeeze, mix and spray.
