The outdoor bagged shiitake mushroom has a wide range of raw materials, and the bioconversion rate is 8 to 10 times higher than that of the segmental wood cultivation, and the quality is high and efficient. In order to produce more and better mushrooms, I have been groping in production and summed up a set of management methods for the color change of mushrooms, which greatly improved the quantity and quality of the mushrooms. Now introduce this method as follows: "One control": that is, the early control of the temperature. 3 to 4 days after bag removal, the temperature inside the cover film of the mushroom bed is controlled at 25 ° C. It is not necessary to uncover the film and ventilate. The purpose is to make the bagged mushrooms rejuvenate at moderate temperature. After 4 days, ventilate 1 or 2 times a day (time is 30 to 40 minutes), and increase the temperature difference, so that the aerial hyphae are inhibited and not excessively prolonged.
"Two sprays": that is, the secretion of water spray off. Generally, 7 to 8 days after bag removal, the hyphae begin to spit out the yellow water beads. At this time, it should be treated in time. Otherwise, the bacteria will be self-dissolving and easily infected with bacteria, or the bacteria will be thickened. To do this, it must be sprayed with water in time. On the first day, spray it on the fungus with a sprayer, dilute the yellow water beads, and rinse the water with a pressure sprayer the next day. When the tube is slightly dry, cover the film.
"Three solutions are difficult": that is, it is difficult to turn the color. Mainly do ventilation and ventilation (not less than twice a day, 30 minutes each time). When the temperature is high, the film should be unsealed in the morning and evening, and the temperature difference should be widened to control the temperature of the mushroom bed in the color changing period to 15 °C ~ 20 °C. If you find that the color change is too light or does not change color, you can spray water to humidify, tightly cover the film, or put the fungus on the ground, use the ground temperature and the ground to promote the color change; if the hyphae do not fall down, you can uncover the film at noon. 1 to 1. 5 hours, let the bacteria tube contact with light or dry air, causing the hyphae to fall and then enter the color change. If the above treatment is not effective, it can be lightly sprayed with 3% lime water, and the membrane should be covered after drying.
