Preparation of topdressing for Edible Fungi

During the peak period and the later stage of mushroom emergence of edible fungi, the nutrients in the culture materials were exhausted. Timely topdressing fertilizer in these two periods can significantly increase the yield and improve the quality of edible fungi.

1. Manure and soil fertilizer: crushing fresh dried pig and cow dung, pre-wet composting with lime water for 15 days, adding 50% fat mud and a small amount of plant ash to mix well, when the yield drops sharply or dead mushrooms appear, the old roots are removed and scattered on the bed surface combined with cleaning the bed surface.

two。 Grass juice: using the rotten and sun-dried forage, add 100 times water to extract the juice, cool and spray, it can make the edible fungus grow healthily.

3. Cottonseed juice: add 10 times water to cottonseed juice, cool and add 3 times water to use.

4. Pig and cow urine: boil the rotten pig and cow urine for 20 minutes, filter out the residue, add 10 to 20 times of water to form a 5% to 10% dilution.

5. Food liquid: ① soybean water. Rinse 10 kg of non-moldy soybeans, soak and add 50 to 60 kg of water. after boiling thoroughly, filter out the soup and spray it with water to 200 kg. ② cut up 10 kilograms of carrots, add 15 kilograms of water, boil for 30 minutes, filter the juice and add 3 times the water to form a 25% Fresh Carrot Juice spray. ③ adds 1 kg of solid glucose to 100kg water and dissolves to get 1% glucose solution, which can be sprayed directly. ④ is sprayed in 100kg of water mixed with 0.3kg to 0.5kg of salt.

6. Mushroom root soup: take 5 to 10 kilograms of mushroom roots, slightly wash clean, add 10 to 15 kilograms of water and boil for 15 minutes, take clear liquid and add 50 kilograms of water, stir and spray, which can promote the growth of small mushrooms.

The above-mentioned topdressing solution is about 0.5 kg per square meter.
