Cultivation of Dictyophora by soybean shading

The original cultivation of Dictyophora uses bamboo shavings as raw materials, and the cultivation yield is low (20ml 30kg / mu). Since 2000, the country has pioneered to use grain husks as raw materials to cultivate and build shade sheds. The yield per mu has been increased to 120kg per mu, and the benefit has been increased by 4 times. Since 2001, soybean has been used for sunshade cultivation. The yield per mu is 100ml and 150kg. Without the shading shed, the wood can be saved by 3mur5 cubic meters, and the cost per mu is reduced by 600 yuan. After the successful demonstration of 1000 mu in 2004, it was vigorously promoted in Taining County, with an annual planting area of more than 2000 mu, of which the output value in 2005 reached 15.6 million yuan, with remarkable economic benefits. The main technical measures for the cultivation of Dictyophora by soybean shading are as follows:

I. selection of land plots

1. Location requirements: a half-yin and half-yang site with convenient drainage and irrigation.

2. Soil quality requirements: the soil is fertile and loose, not easy to consolidate, and the slightly acidic loam with good aggregate structure.

3. Field requirements: the cultivated fields have not planted Dictyophora in the past 4 years, and the fields in the upper hills of last year have not planted Dictyophora.

II. Bed consolidation

15 days before sowing, remove miscellaneous apple, discard sundries, plough and turn the soil. After a few days of sun exposure, the bed is 30 cm wide, the bottom is 70 cm wide, the height is 45 cm 50 cm, and the ditch width is 25 mi 30 cm, depending on the field.

III. Preparation of training materials

Husk preparation can be carried out year-round, using 100% husk cultivation, sowing with water will be soaked, soaked, the water content can reach 65%-75%.

IV. Strain selection

1. Strain selection: Dictyophora Dyou42.

2. Strain requirements: the hyphae are white, the hyphae are thick, the aerial hyphae are dense, and the bacteria age is 60 cents and 70 days.

5. Sowing seeds

1. The sowing time can be from February to May, and the sowing usually begins after the 15th day of the first lunar month.

2. Methods: layer sowing was used to open the ditch from the border surface, 10 cm wide and 15 cm deep, and the bottom of the ditch was 5 cm thick; then sowed a layer of bacteria (700 bags of bacteria per mu), covered with 10 cm thick husk and covered with soil 3 cm 5 cm. After sowing, the straw on the border cover was about 2 cm thick for heat preservation, moisturizing and weed control.

3. Soybean interplanting: sowing time, sowing after sting, interplanting can be directly planted in the bamboo shoot border surface, the standard spring soybean single row hole sowing distance is 25ml 30cm, the soybean hole sowing distance is 2025cm.

VI. Management

1. Temperature: according to natural conditions.

2. Moisture: generally available according to natural conditions. ① continuous sunny week can be appropriate spray moisturizing; ② in a dry year can run horse water soak L3 hours; ③ timely drainage, before the coming of the rainy season to dig a good drainage ditch around the cultivation site, drainage ditch to be more than 30 cm deeper than the border ditch, timely drainage, in order to avoid high water content at the bottom of the bed resulting in anaerobic fermentation, resulting in culture material blackening.

Mycelium growth: after sowing, the mycelium was filled with culture material for 40 days, the fungal cords matured after 15 days, and climbed onto the soil after 15 days, and the bacterial balls were formed after 20 days. The mycelium balls appeared until the fruiting bodies were formed, and it took about 30 days to harvest, that is, picking usually began at the end of May and the beginning of June.

VII. Harvest

Pick Dictyophora skirt in time when it reaches its maximum opening. When harvesting, it is best to cut the fungal cords at the base of the fungal receptacle with a knife. In order to improve the product quality of Dictyophora, it can be picked before the skirt of bamboo sun fruit body, cut off the cover with a knife immediately, then cut the cover gently and longitudinally, peel off the dirty green tissue of the cover, discard the fungus receptacle, and bring it back in the bamboo basket. After the fungus skirt is placed normally, it is placed on a bamboo screen with gauze for air drying.
