Fast-growing and High-yield Management techniques of Lentinus edodes

In the fast-growing and high-yield production of Lentinus edodes, its supporting management technology is very important, which directly affects the yield and quality of Lentinus edodes.

I. Management of the germicidal period

The inoculated bacterial bag was moved to the culture room, the room temperature was controlled at about 25 ℃, and the relative humidity was less than 75%. During the germicidal period, due to the heat released by mycelium respiration, the temperature in the bag will be 2 / 4 ℃ higher than that outside the bag. During the germicidal period, attention should be paid to prevent the temperature from being too high, especially the room temperature should not exceed 25 ℃ in the middle and later stage. 15-20 days when the mycelium grows to 8cm in diameter, the tape can be opened from the bottom up to make the opening face down to speed up the mycelium growth and turn the pile and check at the same time. The second turn was carried out 30-35 days after inoculation. When the mycelium grows so long that the two holes meet, remove the tape and dig out the seed block.

II. Management during the period from taking off bags to changing colors

The main results are as follows: 1. If the bag is removed too early at the right time, it is not easy for the bacteria to change color; if the bag is removed too late, the bacteria will be too thick, which will affect mushroom production. It is necessary to master two points when taking off the bag at the right time: one is to master the bacterial age of Lentinus edodes, the early-maturing species are generally 60-65 days, and the mid-late-maturing varieties are 70-80 days; the other is to look at the tumorous hyphae on the bag wall, accounting for 1 inch, 2 pounds, 3 or local brown spots, it is the most suitable time to take off the bag.

2. The speed of normal color change, the depth of color and the thickness of bacteria are closely related to the number of mushrooms and the quality of mushrooms. The normal color conversion is brown, the thickness of the quilt is moderate, the mushroom is normal, the mushroom body is round, medium and large, the quality is good and the yield is high. The unbagged tube rod was placed on the shelf of the mushroom bed at an inclination of 70 °at a distance of 10 cm, so that the mycelium could resume growth. The temperature of the mushroom bed was controlled at 23-25 ℃, and the relative humidity was maintained at 85%. Under suitable temperature and humidity conditions, a layer of thick white fluffy hyphae will grow on the surface, then the film at both ends of the mushroom bed will be opened and ventilated once in the morning and afternoon for 30 minutes each time.

3. 10-12 days after the bud was removed from the bag by changing temperature, the color of the bacterial tube basically changed, and the temperature difference between day and night should be more than 10 ℃, which was beneficial to the formation of fruiting body primordium. Cover the film tightly during the day, reduce ventilation to keep the tube moist and raise the bed temperature, but no more than 25 ℃ at night, open the film at night, let the breeze blow gently, dry the surface of the tube, and be stimulated by low temperature, the air relative humidity is maintained at about 85%, and the primordium develops into a mushroom bud after 3 to 4 days of temperature stimulation.

III. Management of mushroom production period

When the mushroom bud cap grows to 2cm, start spraying water. If the temperature is above 20 ℃, spray once in the morning and evening. At the same time, pay attention to ventilation to prevent deformed mushrooms. In the mushroom growing stage, the fungus tube is mainly watered and moisturized in the early stage, and soaked and sprayed in the later stage. Lentinus edodes is an aerobic organism, pay attention to ventilation during the mushroom period, and keep the air fresh. The light of mushroom farm is "three yang and seven yin" in autumn, "five yang and five yin" in winter, "four yang and six yin" in spring and "one yang and nine yin" in summer.

IV. Prevention and control of diseases and insect pests

The control of diseases and insect pests is a very important part of the fast-growing and high-yield technology of Lentinus edodes. We should adhere to the principle of "giving priority to prevention and combining prevention and control". Once bacterial pests, insect pests and diseases are found, it is necessary to analyze carefully, judge the cause, and take comprehensive measures such as ecological control, biological control and chemical control as soon as possible to completely eliminate or restrain their spread.
