The experiment found that as long as the management is strengthened, planting dictyophora in the north can also achieve better benefits. The cultivation method is as follows:

1. Site layout: Choose sunny, ventilated, fertile farmland with convenient irrigation and drainage. Bed soil preparation, width 1m, height 30cm, indefinite length; The border spacing is 50cm, and the border surface is paved with 10cm rich soil and leveled. Then spray 5% formaldehyde solution on the frame and seal it for 12 hours. Before sowing, cover the border with 5 cm thick mature fertile soil, and then spray the border with 0.3% dichlorvos solution or limewater. Sunshades are set around the site, and the light intensity requires "four shades and six suns".

2. Preparation of culture medium: The formula is corncob 48%, corn stalk 30%, sawdust 20%, gypsum powder 1% and calcium superphosphate1%; Or sawdust 68%, soybean straw 30%, gypsum powder 1%, sugar 1%. Before use, corncob should be crushed into 2cm pieces, and corn stalks or soybean stalks should be cut into 3cm long pieces; Mechanical slicing of miscellaneous wood. Dry the raw materials first, then bag them and soak them in clear water for 5 days, or soak them in 0.5% lime water for 2 days, then rinse them with clear water, take them out and drain them. 20kg of material per square meter, with a water content of about 65%.

3. Cultivation season: it can be cultivated twice a year: spring seeds are sown in early May and harvested in August; Autumn planting is sown in September and harvested in the following summer.

4. Sowing: Sowing in layers. First, spread a material with a thickness of 5cm on the bed surface, and sow it by means of on-demand or broadcast sowing, then spread a culture material with a thickness of10cm on it, slightly compact it, and then sow a layer of strains; Spread 5cm thick culture material on it, compact it, cover the leaves and residues, and then cover it with soil. Cover the frame with 5 cm soil, cover the frame with 2 cm soil, cover it with film, and keep warm and moist. Use 8 bottles of seeds per square meter, the seeds should not be too broken, and the broad beans should be the right size.

5. Bed management:

① Germination stage: after sowing, cover with film, keep the temperature at about 25℃, and ventilate once a day for 30 minutes each time; No water spray for a month.

② budding stage: after 30 days, when the white fluffy hypha is covered with the edge, cover it with 1cm sterilized fertile soil, and then sprinkle a layer of leaves or pine needles. When the mycelium is twisted into germ, water is sprayed on the border every day, keeping the air humidity at 80% and the temperature at 25℃.

(3) fruiting period: after 40 days, fruiting bodies are formed one after another, the temperature is controlled at 28%, the humidity is kept at 90%, the water spraying time is before 7: 00 in the morning, and ventilation is generally conducted once a day. When the temperature is high, ventilate once every morning and evening for 30 minutes.

6. Overwintering management: Dictyophora dictyophora can be harvested once every two years, but in the north, it is an important link to overwinter Dictyophora dictyophora. The specific method is: before and after the first frost, before the soil begins to freeze, cover the bed with weeds and leaves, and the thickness is about 15cm. Water the bed with frozen water before covering the soil, so that the bed and the ditch beside the bed can be filled with enough water. When the soil began to thaw in the next spring, the cover was uncovered twice, once every 7 days, and then it entered the normal mushroom production management.
