What should be paid attention to in harvesting edible fungi?

1. Grasp the best harvest time. All kinds of mushroom ears are basically mature in seventy or eighty percent, and their appearance is beautiful and taste good. Take shiitake mushroom as an example: seven or eight mature signs, that is, the bacterial membrane has been broken, the cap has not been fully developed, there are still a few rolls inside, forming a "gong edge"; the pleats have all elongated and turned from white to brown or dark brown, which is the most timely harvest period of shiitake mushroom. The shiitake mushroom harvested at the right time has bright color, strong fragrance, thick cap and soft meat.

Second, pay attention to picking technology. Edible mushroom picking, all mushrooms with stems, such as mushrooms, mushrooms, straw mushrooms, Agaricus blazei, bamboo shoots, etc., must be picked according to the principle of picking large and keeping small. When picking mushrooms, pinch the base of the mushroom handle with your thumb and forefinger, rotate it left and right, and then gently pull it up. Be careful not to bruise the mushroom buds. For colloid fungi such as Tremella, Auricularia auricula, Auricularia auricula, Pleurotus ostreatus, Pleurotus ostreatus, etc., cut off the whole flower from the base with a sharp knife when harvesting, and pay attention to keeping the flower shape intact.

Third, choose suitable weather. Sunny harvest is conducive to processing, rainy days high moisture content, difficult to dry, affecting quality. But if the mushroom ear is ripe, it should be harvested in time on rainy days, but it should be processed as soon as possible. For black fungus, tremella and the like, can be taken to stop spraying water, strengthen ventilation, such as fine harvest.

IV. Suitable containers shall be equipped. Fresh mushrooms should be packed in small baskets or baskets, and should be handled gently to keep the fruiting bodies intact and prevent mutual extrusion damage. In particular, sacks, barrels, wooden boxes and other containers should not be used to avoid appearance damage or mildew. Fresh mushrooms should be collected according to the size of the mushroom body, flower shape good or bad for sub-packaging, in order to process.

5. Water supply and humidity control before mining. If water is sprayed before harvest, the water content of mushroom body is too high, the pleat will turn brown during processing, and if dehydrated and dried, the pleat will turn black, and the product does not meet the export requirements. If it is fresh, too much moisture will also cause mildew. Therefore, stop spraying water before harvesting to keep the mushroom body normal moisture.
