How to prepare top dressing for edible fungi? Specific methods introduced

During the peak fruiting period and the late fruiting period of edible fungi, the nutrients in the substrate are nearly exhausted. Applying top dressing in time at this stage can significantly increase the yield of edible fungi and improve quality.

1. Manure soil fertilizer: Crush dried pig and cattle manure, pre-wet it with the supernatant of lime water and pile it for 15 days, add 50% fertile mud and a small amount of plant ash, mix well. When the yield of edible fungi drops sharply or dead mushrooms appear, clean the bed surface, remove old roots, and spread the manure soil fertilizer on the bed surface.

2. Straw liquid: Take decomposed and sun-dried straw, add 100 times water and decoct to extract the liquid. After cooling, spray it, which can make edible fungi grow robustly.

3. Cottonseed liquid: Add 10 times water to cottonseed and decoct to make a liquid. After cooling, add 3 times clean water before use.

4. Food liquid: Take 10 kg of soybeans that have not become moldy, wash them clean, soak them, then add 50-60 kg of water, boil, filter out the soup, add water to 200 kg and spray; take 10 kg of carrots, chop them, add 15 kg of water, boil for 30 minutes, filter to obtain the juice, add 3 times water to make a 25% carrot juice and spray; add 1 kg of solid glucose to 100 kg of water, and after it dissolves, a 1% glucose solution is obtained, which can be sprayed directly.

5. Mushroom root soup: Take 5-10 kg of mushroom roots, wash them clean, add 10-15 kg of water, boil for 15 minutes, take the clear liquid and add 50 kg of water, stir well and spray, which can promote the growth of mushroom buds.

The amount of each of the above top dressing liquids used is about 0.5 kg per sq m.
