How to sow mushroom cultivation in open field

First, the election and preparation

1, the election. In principle, it is desirable to choose non-stick, untamped and undrought sandy land blocks for easy management. It is better to go east and west.

2, site preparation. In the autumn, the root crop of the former crop was removed and the net was made into a trough that was 60 cm wide and 10-15 cm deep. The bottom of the trough was in the middle and the two sides were low, resembling turtle backs. The mushrooms will be planted in the fields from March 15 to April 15.

Second, preparation before broadcast

1. Preparation of tertiary bacteria and culture materials. Three species (production species) generally need 18-20 bottles per square meter. The formulation of cultivation materials is: sawdust 78%, wheat bran 10%, rice bran 10%, gypsum 1.5%-2.0%, plus carbendazim 0.1%, shavings or rice hull not more than 5%. Mix evenly the moisture content of the culture material to 60%. Steam sterilization, will be equipped with a good culture material, steamed on the steamer, the temperature above 97 °C steamed for 2 hours to pan, into the sterile woven bag Zhakou home cool to 20- Can be sown at 25°C.

2, straw curtain and rack preparation. Exposed mushrooms need to be shaded with straw curtains. The straw curtain can be made of various straws, straws, tree strips, etc. The width is 85-100 cm and the length is not limited. Racks take various trees, 1-1.2 meters long.

3, other material preparation. The polyethylene film was selected to be 0.01-0.014 mm thick and 1.5 m wide by an ordinary film. The inoculation box is made of wood that is 8 cm wide (not long). Quicklime is prepared at 200 grams per square meter. In addition, prepare some 50-55 cm long corn stalks or straw and disinfect it with 1% carbendazim before use.

Third, sowing

First excavate the bacteria from the bottle (bag), remove the old skin and then dice into small pieces. Use 2/3 of the bacteria to mix well with the cool culture medium, sow it in the inoculation box covered with plastic film, and then fill it with a hand or a wooden board to form a turtle shape, and then add the remaining 1/3 bacteria. Spread evenly onto the surface of the material, and then use the wood to make the material surface. Put a sterilized corn stalk or rice straw every 15-20 centimeters in the horizontal direction, put one in the middle longitudinally, then reply the plastic film on the other side, and set up on both sides without exposing the culture material and then cover the soil. Thickness can be centimeters.
