Production technology of Grifola frondosa in greenhouse in winter

1. Greenhouse construction: the greenhouse is an ordinary vegetable greenhouse, no ventilation holes are reserved. The ventilation uses heated air to enter the greenhouse through the ventilation pipe, which effectively solves the contradiction between ventilation and heating in the production of edible fungi in winter. The heating in the shed is heated by boiler hot fan. The temperature is self-determined and unattended by using microcomputer technology.

two。 Bacteria rack setting: the use of shelf structure increases the production area, effectively increases the output value and reduces the production cost.

3. Construction of bacterial rack: the construction of bacterial rack can be made of a variety of materials to build a long slot with a width of 1 meter and a height of 25 centimeters. the length is self-determined according to the length of the shed, and can be designed to have no partition or partition. Pay attention to two points, one. A space of not less than 35 cm should be set aside between the upper and lower floors for Grifola frondosa growth, ventilation and light. two. The dual-use of the bacterial rack should be set aside according to the length of the drain hole, so as to avoid bacterial bag rot caused by excessive watering in the future.

4. Irrigation system: using 5-hole micro-spray belt, hanging above the bacterial rack 20 cm. Be careful not to be too low so as not to cause obstacles to the growth of Grifola frondosa.

5. Heating system: the external boiler is used to avoid oxygen competition with Grifola frondosa in the shed, and the hanging hot fan is used in the north wall of the shed. Pay attention to the wind direction facing the wall, do not blow the bacterial rack directly.

6. Ventilation system: ventilation duct with external heating air is directly ventilated every 6 meters, and the ventilation pipe is not more than 1. 5% on the north wall. The height of meters.

7. Humidification system: use portable humidifier.

8. Soil cover thickness: our base uses soil cultivation to ensure the quality of Grifola frondosa. According to the planned mushroom production time, we can choose 2 Murray 5 cm soil layer thickness, all of which can produce mushrooms well.

9. Temperature control: using a microcomputer to automatically control 24 degrees during the day and night to stimulate the temperature difference of 5 to 10 degrees according to different stages of mushroom production.

10. Irrigation and watering: soak in flood for 24 hours on the first day of cultivation, pay attention to the time should not be too long. Then the daily routine watering is carried out according to the mushroom stage.

11. Humidity control: in general, water can be sprayed on the wall, increasing the number of micro-spraying can meet the humidity requirements of Grifola frondosa. There is no need to use a humidifier, only for a short time during the day after Grifola frondosa leaves.

twelve。 Lighting control: the sunshade net is hung first in the shed to filter the light, and the single-layer or double-layer sunshade net can be selected for better lighting.

13. Discoloration treatment of Grifola frondosa: increase the temperature difference to 10 degrees Celsius 72 hours before picking. Increase the light intensity appropriately.
