Preparation and application of mushroom fertilizer topdressing solution

In order to increase the yield of mushrooms, fertilizer must be applied properly. The author introduces the preparation and application of several kinds of mushroom topdressing solution as follows:

1. Chemical fertilizer liquid. With 0.1% 0.2% urea solution or 0.5% ammonium sulfate solution, sprayed once every 2 days (days), the fruit body of mushroom was thickened and thickened in the middle and later stage with the degree of spraying wet bed. Use calcium superphosphate 0.5kg, add water 15kg to dissolve and take filter juice, add ammonium bicarbonate 50g or ammonia water 150ml to neutralize ammonium phosphate and spray on the bed surface, which can thicken the mushroom body and increase the yield by 15% to 20%.

2. Fresh Carrot Juice . Take carrot 10kg chopped, add water 15kg boil 15min (minutes), filter juice, add water 40 times, spray bacteria bed 300~400m2, can increase mushroom yield by 10% to 15%.

3. Triacontanol solution. Spraying the triacontanol diluent with 0.4~1mg/kg concentration on the bacterial bed can improve the mycelium vitality; when sprayed in the fruiting body soybean grain size, the weight gain rate is up to 7.5%, and the mushroom can be picked 3 days in advance; and the mushroom is thick, white, strong and less open, and the yield is increased by 25% and 30%.

4. Mushroom root soup. Wash the mushroom feet and crushed mushrooms cut off during harvesting and processing, cut them into thin slices, add 1 kg of material and water 1~1.5kg, and spray mushroom bed 30~40m2. The fruit body can be thickened and the peak period of mushroom production can be prolonged when used in the peak period of mushroom production.

5. Plant healthy nutrient solution. 1000 times diluted solution (2g of 1m2 bed dosage to water 1kg) was sprayed with plant health factor "Jinjang No. 1" powder. Spray this liquid once after spraying mushroom water each time, after spraying, the mushroom is thick and fruiting, the yield is increased by about 30%, and the fresh-keeping period and harvest period can be prolonged.

6. Bean oar juice. Take soybean 2kg, add water to soften and grind into pulp, filter the residue and add water 80~100kg, which can spray mushroom bed 80~100m2, which can promote the body of mushroom to be stout and white.

7. Disease resistance regulates nutritional enhancers. The physiological diseases and abnormal mushrooms can be avoided by spraying soybean grain size (250300ml/m2) in mushroom fruiting body with 1000 times solution of multifunctional disease resistance regulating nutrition enhancer "Lubokang", and spraying once every 5 ~ 7 days (days).
