Latest tutorial on management techniques for oyster mushrooms during the spawn-running period
The period from sowing to the appearance of fruiting bodies is called the spawn-running period. The quality of management techniques during this stage is the key period that determines whether the oyster mushroom mycelium can grow and spread through the substrate, and whether high quality and high yield can be achieved. So how should the spawn-running period of oyster mushrooms be managed? Follow along with the editor to take a look at the detailed introduction.
1. Strictly control light
During the spawn-running period, avoid light as much as possible, and especially do not allow strong light exposure. At present, many growers take an indifferent attitude toward this, which is neither scientific nor extremely harmful to oyster mushroom spawn running. If oyster mushrooms receive prolonged light stimulation during the spawn-running period, the bags may form primordia as soon as spawn running is completed, making it impossible to carry out the fruiting schedule at all. The correct approach is to shade the light immediately after sowing. Apart from operations such as entering to observe and turning the bags, no light should enter the mushroom shed at other times.
2. Temperature and humidity regulation
The suitable temperature for mycelium is 25 degrees. If spawn running is carried out in a low-temperature season, a stove can be used to raise the temperature. If conditions are poor, a black plastic film or shade net can be hung above the inside of the shed, and on clear days the straw curtain can be removed to raise the temperature inside the shed. However, direct sunlight must not fall on the spawn bags. If conditions permit, a water-temperature air conditioner can be installed, which can play a role in all four seasons. Air humidity has a relatively large effect on spawn running and needs to be handled carefully. For example, in spring, when the climate is dry, humidification should be provided during this period, generally adjusted to about 70%. In summer, when it rains for a long time and humidity is high, dehumidification is needed to ensure normal spawn running.
3. Reasonable ventilation
Mycelium needs a small amount of oxygen during growth, and slight ventilation can meet its needs. However, attention should be paid to the temperature exchange inside and outside the mushroom shed. When the temperature difference is too large, an appropriate ventilation time should be considered. For example, when spawn running in summer, ventilation should be chosen as much as possible at night, and in low-temperature seasons it should be chosen at noon, avoiding the high-temperature and low-temperature periods as much as possible.
4. Prevent pests and diseases
Throughout the entire spawn-running period of oyster mushrooms, spray a solution of Bingqu Wuzong or Saibai 09 about once every 5 days. This is to prevent the occurrence of contaminating fungi and diseases. Once contaminated spawn bags are found, promptly move them out of the arched shed for separate production. Especially in spring, pyrethroid substances should be sprayed frequently to kill pests.
