1. Clean the surface of materials so as to eliminate sundry fungus contamination caused by waste mushroom roots.
2. Let mushroom bags have a short rest for 3-5 days, enhance the ventilation of greenhouse and keep a slightly-dried material surface so as to promote the growth of mycelia in compost.
3. Supplement nutrient solution that carries proper concentration. During the production of the second flush of mushroom, a vast number of Nitrogen and Potassium have been absorbed by sporocarps from compost, which results in imbalance of carbon nitrogen ratio, in that case, cultivators should supplement Nitrogen and Potassium in time.
4. Add nutrient solution in accordance with the picking amount, be sure to master the principal of “Less can be more,” 2-3 days after the supplementation, be sure to check whether all nutrient solutions have permeated into compost in the bag, if you get bad answer, immediately pour it out.
5. 2-3 days after supplementing nutrient solutions, you could cover mulching film so that concentration of carbon dioxide surrounding sporocarps could be increased and promote quick bud-emergence. Meanwhile, it also facilitates promoting the extending of mushroom stipes and eliminating oversize caps.
