Detailed Description
1. At present, the cause analysis of low quality and low yield of the black fungus:
through long-term observation and research, the applicant has long-term existence of fungus stick lower part (about one quarter part) fungus swelling and falling off and rotting in the production of the black fungus is a main cause of low quality and low yield of the current black fungus, and further research discovers that as the length of the fungus stick in the black fungus bag reaches 53-55 cm, the water content of the culture medium in the bag reaches 55% -60%, and water needs to be sprayed to the fungus stick frequently after the field is discharged, under the action of gravity, the water in the bag is settled downwards, and the bottom of the bag is closed, so that the settled water is accumulated at the lower part of the bag, about one quarter of the lower part is in an overstock state for a long time, even the culture medium at the lower part is completely in a water bubble, which causes poor growth and ear swelling and falling off of the black fungus stick of the lower part of the fungus stick, even the rotten stick, not only causes that part of the black fungus is small in size and poor quality, but also causes yield reduction when falling off the rotten stick appears.
2. Solving the problems and going out of the way:
the applicant has repeatedly studied to find that the basic solution to the above problems is to control the water content in the lower part of the fungus stick, i.e. to keep the water content in the upper and lower parts of the fungus stick balanced even when water is sprayed frequently after the fungus stick is discharged, and especially the water content in the lower part is not out of standard. Therefore, the applicant has tested to prick the lower part of the fungus stick, but the problem that the drainage is not smooth can not be solved because the bottom of the fungus stick is directly pressed on the ground. Therefore, the applicant designs a fungus stick stem with a drainage groove, so that the fungus stick frame is separated from the ground, and when water in the fungus stick is gathered and sunk to the bottom of the fungus stick, the water can be smoothly discharged from the drainage groove of the fungus stick stem, thereby maintaining the water content balance of the upper part and the lower part of the fungus stick, and the water content balance is also maintained when water is sprayed frequently in time. The results of comparison experiments for several years prove that the quality and the yield of the black fungus are greatly improved.

(1) A field discharge method: during the field discharge, the black fungus stick core column is soaked in lime water or bleaching powder with the concentration of 1% in advance to prepare and sterilize, one end of the fungus stick is directly inserted into the upper section (slightly longer end) of the fungus stick core column until the fungus stick baffle is tightly attached to the bottom end of the fungus stick, the fungus stick and the ground are inclined to lean against the support at the angle of 60-70 ℃, and a fungus stick core column ground label (slightly shorter end) is inserted into a bed to fix the fungus stick. Each cross bar is provided with 6 to 7 bars, the distance is 10 to 15cm, and the bars are uniformly distributed. 8000-10000 mycobars can be discharged per mu. Compared with the prior in-line method, the method for producing the black fungus by using the fungus stick core column has the advantages that: firstly, clean production is realized. The tail end of the black fungus stick is lifted off the ground, so that sediment is prevented from splashing on the lugs at the bottom end of the fungus stick during water spraying; secondly, the ventilation is increased. The fungus stick frame of the fungus stick leaves the ground, the ventilation of the fungus stick at the lower end is increased, and the phenomenon that the ear pieces at the lower end of the fungus stick fall off due to poor ventilation, high water content and swelling of the ear pieces is avoided; thirdly, the water content is reduced. The water deposited at the lower end of the fungus stick is discharged through the raising and draining groove of the fungus stick core column, so that the water content is reduced, and the rotting phenomenon of the fungus stick at the lower part is avoided. Fourthly, the damage of insects and grass is reduced. The fungus sticks are directly discharged on the furrow, are vulnerable to damages of pests and weeds, not only cause yield loss, but also easily cause the phenomenon of pesticide residue exceeding standard caused by pesticide killing and weeding of farmers. (2) environmental moisture control: the ear-promoting temperature is between 15 ℃ and 23 ℃, and the day-night temperature difference is increased, so that the formation of ear buds is stimulated. After the field is arranged, the fungus sticks are not sprayed with water directly before the formation, and in the dry weather with continuous windy days, the spatial humidity is increased by adopting a mode of humidifying the bed of a sprayer or irrigating water in a drainage ditch; when the earbase grows into small earpieces after formation, water is sprayed for 1-2 times per day, the water spraying amount is increased along with the growth of the earpieces, the water spraying principle of 'dry, wet and dry' is mastered, and the water is sprayed more in sunny days, less or no water is sprayed in rainy days, more large ears and less small ears.
Eighth, harvesting and drying:
1. harvesting time: when the ear stem is thin, the ear flap is stretched and slightly sagged, the color turns light (from black to brown), and the ventral spores do not occur in a large amount, the collection can be carried out in batches. 2. The water is not sprayed 24-48 hours before harvesting, when harvesting the ears, one hand holds the ear bag, the thumb and the index finger of the other hand are used for pinching the root of the ears, and the user slightly twists the ear to pull the ear upwards. 3. Post-harvest treatment: the collected mature lugs should be immediately removed of impurities, and the clustered flower shape is broken into single pieces according to the lug shape. The bamboo chips or the sunshade net can be directly aired in sunny days; the ear faces upwards and the root faces downwards during airing; when not dried, the utility model is not turned randomly so as not to cause boxing ears; if the black fungus is in continuous overcast and rainy weather, the collected black fungus is placed in a refrigerator for storage at the temperature of below 4 ℃ and is dried in the sun.
4. The invention has technical promotion effect on the industry
The fungus stick core column and the method for producing the black fungus by using the fungus stick core column developed by the invention greatly improve the yield and quality of the black fungus and realize clean and harmless production of the black fungus. The method has the specific advantages that:
1. the water content of the lower part of the fungus stick is reduced: the fungus stick core column with the drainage groove extends into the fungus stick, so that moisture deposited at the lower end of the fungus stick seeps out through the drainage groove, the water content is reduced, and the lower fungus stick is prevented from being rotten.
2. Increasing the ventilation: the fungus stick frame of the fungus stick leaves the ground, the ventilation of the fungus stick at the lower end is increased, and the phenomenon that the ear pieces at the lower end of the fungus stick fall off due to poor ventilation, high water content and swelling of the ear pieces is avoided;
3. clean production is realized: the lower end of the black fungus stick is supported off the ground, so that sediment is prevented from splashing on the lugs positioned at the bottom end during water spraying;
4. the insect and grass harm is reduced: the fungus sticks are directly discharged on the furrow, are vulnerable to damages of pests and weeds, not only cause yield loss, but also easily cause the phenomenon that pesticide residues exceed standards due to the deinsectization and the weeding of farmers.
In order to verify the technical effect of the invention, the applicant devised a comparative test, the results of which are as follows:
TABLE 1 Auricularia auricula quality produced by the conventional method (per 1000 bars field production results)
