The deformity of Lentinus edodes affects the appearance of Lentinus edodes how to prevent the deformity of Lentinus edodes

Lentinus edodes fruiting bodies often appear "candle mushroom" (with handle but no cover), "pineal mushroom" and "litchi mushroom" (cover group without stalk or umbrella). These are all deformed Lentinus edodes and belong to physiological diseases. How to prevent it, there are the following points:

Deformity of Lentinus edodes

1. Correct introduction: before cultivation, we must first find out the characteristics of the strain, select suitable varieties of Lentinus edodes according to local conditions, arrange a suitable inoculation season, and calculate the scheduled inoculation time.

2. Familiar characteristics: if the bag is removed too early, the mycelium physiology is not mature, and there are many mutant mushrooms. The sign of physiological maturity of mycelium is "one bacterial age, three standards". "one bacterial age" is about 60 days from the date of inoculation; the "three standards" are that the vesicular hyphae with tumor-like protuberances in the bag account for 2 / 3 of the whole bag, partial brown, hold the bacterial bag in hand, and have soft bullet sexy.

3. Control the temperature: during the color changing period, pay attention to the change of air temperature. The temperature is within 25 ℃ for the first 3 days. It is not necessary to uncover the film on the mushroom bed. Under normal circumstances, the color change ends in 12 days, and the first tide of mushrooms appears 3 days later. Master the principle of temperature change, prevent the stimulation of temperature difference is not enough: correct method of temperature change: cover the mushroom bed with film during the day, and open it for 1 hour after 12:00 at night, so that the temperature difference between day and night is more than 10 ℃.

4. Good humidity of the palm: soak in the right amount of water in time, and the waterproof humidity is too low too early: when the moisture content of the mushroom tube is less than 40%, it is difficult to produce mushrooms and there are many small mushrooms, generally when the weight of the mushroom tube is 30% less than the original.

5. Ingenious mushroom promotion: the mushroom method should be appropriate to prevent it from being dry and wet. After each harvest of mushrooms, the film must be uncovered and ventilated for 6-7 days, so that the hyphae absorb enough oxygen to restore their growth ability, and then turn to spray moisturizing, dry and wet alternately to urge the next tide of mushroom buds.

6. Timely harvest: Lentinus edodes is covered with crimped edge, picked when the stalk is moderate, and picked once a day. To the peak of mushroom production in spring, sometimes it needs to be picked twice a day.
