What are the factors that affect the growth of mushrooms?

1. Main factors

Temperature is the primary factor for the growth and development of Lentinus edodes. The temperature of the culture stage and the mushroom production stage should be controlled in the production, which is the environmental basis for ensuring the production. In general, the temperature required for mycelium growth ranges from 15 to 28 degrees, and the suitable temperature should be controlled at 22 to 28 degrees. When the temperature is higher than 28 degrees, the mycelium grows slowly and weakly, exceeding 35 degrees, and the mycelium is close to death temperature. Below 10 degrees, the growth of mycelium is relatively slow, and the sowing amount needs to be increased, but the chance of being contaminated by various kinds of miscellaneous bacteria is very small, which is also the key to planting Lentinus edodes. The temperature range of the fruiting period is 4-28 degrees, 17-22 degrees is more suitable, and about 18 degrees * * * is ideal. Mushroom needs the stimulation of low temperature and temperature difference, which is conducive to the formation of thick mushrooms and high-quality mushrooms.

The following are some reference techniques for mushroom cultivation, hoping to be useful to you.

2. Humidity

Humidity refers to the relative humidity of the air. The relative humidity of the air in the mycelium growth stage should be controlled at 60-70%, the water below 60% of the medium is easy to evaporate, and the water above 75% is easy to form miscellaneous bacteria pollution. The relative humidity of the air in the fruiting stage should be increased to more than 85%, but it is higher than 90% for a long time, which is easy to form rotten mushrooms and cause * * * pests. The relative humidity of the air should be combined with the prevailing temperature and ventilation.

3. Moisture

Moisture refers to the water content in the medium, and the water content of the substitute dry material medium is 55-60%. If the water content is too large and the air permeability is poor, the mycelium will grow slowly. The extension of the growth cycle will give the bacteria the opportunity to infect, resulting in the failure of production.

4, the light.

Lentinus edodes mycelium in the growth stage does not need light, the more in the dark and constant temperature conditions of growth, the better. However, in the stage of fruiting body formation and development, proper light stimulation will be conducive to the growth of shiitake mushrooms and the formation of high-quality commercial mushrooms.

5 the air.

Lentinus edodes, like many kinds of edible fungi, needs sufficient fresh air during the growth of mycelium and the development stage of fruiting. When the concentration of carbon dioxide in the environment exceeds 0. The growth of 03% mycelium will slow down or even stop, and young mushrooms will form deformed mushrooms with long handles and small covers.

6. PH value

The suitable pH value for the growth of mushroom mycelium was 5. 5-6. Between 5.

Seasonal Selection of Planting Lentinus edodes

Spring sowing is from March 15 to April 10 and autumn sowing is from September 15 to October 15. The arrangement of sowing date should also be combined with the climate. Take spring sowing as an example, the appropriate ground temperature is about 10 degrees, that is, the soil can be sown by thawing seven or eight centimeters. Sowing too late, high temperature is easy to burn and cause miscellaneous bacteria pollution.

7, tidy up the mushroom bed

Site requirements for carrying mushrooms: good ventilation, sufficient water source, no waterlogging or drought, not pure clay.

The direction of the mushroom bed is east-west, the width of the mushroom bed is 40-60cm, too wide is not conducive to management, and the culture material in the middle of the bed has a high temperature zone due to poor air permeability, which is easy to burn bacteria. Mushroom beds are 10-15cm deep, slightly deeper in arid areas, slightly shallower in black land and wet plots. Spring sowing * * * is good to dig the mushroom beds before freezing in the autumn of the first year, and slightly tidy up during spring sowing. A trail of about 60cm should be left between the mushroom beds, and corn, sunflowers, etc. can be interplanted on the trail. Mushroom beds should be made into a turtle-back shape with high middle and low sides, and more sites prone to waterlogging should be reserved.
