Detailed Explanation of Key Points of Water Supplementation Technology for Edible Mushroom Bags

Water supplementation of mushroom bags is the most important technical measure for increasing the yield of edible mushrooms, mainly used for edible mushrooms with a relatively long cultivation cycle. The key points to note are:

1. For shiitake mushrooms (Lentinula edodes) and others, water should be supplemented after color conversion is completed and before fruiting begins, replenishing to about 65% moisture content of the substrate.

2. For most edible mushrooms, water supplementation is carried out during the transition period after the first or second flush of mushrooms is finished. The mycelium should be rested first, then water supplemented, and the amount of water supplemented is best controlled at 80%-90% of the original mushroom bag weight.

3. Water supplementation is not suitable when the mycelium is sparse, growth is weak, the temperature is below 5°C, or pests and diseases occur within the substrate. 4. When supplementing water after the third flush, nutrients can be supplemented at the same time, commonly using urea, sugar, potassium dihydrogen phosphate, etc.
