Southern black fungus bag cultivation technology
Black fungus is a well-known traditional edible fungus and has a promising market. The main cultivation techniques of black fungus in the South are described as follows: Variety selection to choose the sub-body large, thick flesh, ventral black, back gray fluffy, taste crisp and not hard, suitable for bag cultivation species. There are 29, 958, 139, 22 hybrids, Shanghai ear 3, Au5, etc. suitable for southern bag cultivation. 2. During the cultivation period, it was determined that the black fungus was cold and heat-resistant and was a moderate-temperature fungus. In case of high temperature and easy to flow ear, it is a big problem in the cultivation of black fungus in the south. The optimum daily average temperature for the growth of Auricularia auricula is 15-20°C. In this temperature range, the growth speed of the fruit body is moderate, and the tide growth period is about 40 days. The yield is of good quality. Therefore, the South is suitable to promote the cultivation of black fungus in the autumn. Autumn planting can ensure that each tide body has enough growth time, and it can also prevent high temperature flow of ears. Specific cultivation period: in the area above 500 meters above sea level, production of fungus tubes from mid-September to early October, ear-starting at the end of October, and harvesting at the end of April; elevations of 300 to 500 meters can also be cultivated, but The physical growth time is relatively short, the tide times are reduced, and the yield is relatively reduced. The growth period of spring fruiting body is too short, the number of tides is small, the yield is low, and the fruiting body often encounters high temperature in the late growth stage, and it is easy to flow the ear, so it is not suitable for spring planting. 3. Formula selection The currently successful formulations are: 1 wood chips 83% to 86%, bran 12% to 15%, calcium carbonate 2%, water content 55%, pH 5.5; 2 wood chips 80% to 83%, bran 15 %~18%, calcium carbonate 2%, water content 55%, pH 5.5. Formula 1 can be selected when the air temperature is relatively high, and Formula 2 is selected instead. 4. The cartridges were made of a 13.560 cm polyethylene bag. Bagging, sterilizing, inoculating, and disinfecting are performed according to conventional methods. Autumn black fungus inoculation time is generally in the second half of September, when the temperature is still high, susceptible to contamination by bacteria when inoculated. Therefore, prevention of pollution is an important part of black fungus cultivation. First of all, we must select the whole bottle (bag) mycelium white, uniform, there is a clear smell of wood chips, there is no light black primordium, a robust growing cultivar; Secondly, we must be sterilized bacteria seed bottle (bag) surface and inoculation room . The amount of bacteria should be relatively more. After 7 days of inoculation, the temperature was controlled at 27 to 28°C and the hyphae were rapidly colonized. After 7 days, the room temperature was controlled at 24 to 25°C. To reduce secondary infections, try not to inflate bags in the early stage. Generally 40 to 45 days mycelium goes full bag. Since the black fungus mycelium is easy to form primordium after the light stimulation, the culture chamber is required to be dark during the culture of the mycelium. 5. The ears management must first select a plot with ample water and ventilation to the sun, and a cultivator in the shed. When the mycelium is full, the fungus tube is moved into the shed and the culturing shelf is set to allow the mycelium to recover after 2 to 3 days. Hole spacing 5 to 6 cm. When you open a hole, use a sharp blade to cut the film about 1 cm of the "/" blade. General open 24 holes per bag, open the hole after the spray cover film moisturizing buds. Should avoid acupuncture at high temperatures. Black fungus is aerobic, hi wet, cold fungus. After the opening of the hole, the relative humidity in the space remained above 90%. After 15 days, a large number of ear buds can be formed. After the formation of the ear, increase the ventilation, 3 to 4 times a day, each time 1 hour, in the relative humidity of 90% or more conditions, ventilation can be all day. Combine water spray when ventilating, spray water should be even and thoughtful. Because poor ventilation and uneven humidity will not be filmed, the formation of chicken ears and loss of commercial value. Rainy days can be opened film rain. At a suitable temperature, continuous showering of water, the ear will grow up quickly, open a good piece. In case of cold weather below 10°C, cover the film and keep moist. High temperature and high humidity can easily cause the flow of ears. Therefore, when the average daily temperature exceeds 21°C, ventilation must be strengthened. Small amount of water or no water spray should be sprayed sooner or later. 6. Harvesting and processing of ear pieces fully developed, softened, appear white powder layer (spore powder) when the water stopped 1 ~ 2 days after harvest. When harvesting, a small amount of ear buds should be left to facilitate the ear of the 2nd tide. Generally, 3 surges can be collected. After harvesting, the ear-based impurities should be cleaned, dried into small pieces, dried or dried.
1. Organic fertilizers are fertilizers that are naturally produced.
[1] Fertilizers are materials that can be added to soil or plants, in order to provide nutrients and sustain growth. Typical organic fertilizers include all animal waste including meat processing waste, manure, slurry, and guano; plus plant based fertilizers such as compost; and biosolids.
[2] Inorganic "organic fertilizers" include minerals and ash. Organic refers to the Principles of Organic Agriculture, which determines whether a fertilizer can be used for commercial organic agriculture, not whether the fertilizer consists of organic compounds.
2. Farming application：
[1] Plant:Processed organic fertilizers include compost, liquid plant manures, humic acid, grain meal, amino acids, and seaweed extracts. Other examples are natural enzyme-digested proteins. Decomposing crop residue (green manure) from prior years is another source of fertility.
[2] Compost provides little in the means of nutrients to plants, but it does provide soil stability through increasing organic matter. Compost does help microorganisms proliferate which in turn breaks down decaying plant material into substantial bio-available nutrients for plant to easily assimilate. Compost does not need to be fully plant-based: it is often made with a mix of carbon-rich plant waste and nitrogen-rich animal waste including human excreta as a means to remove pathogens and odor from the latter.
[3] Grain meals can be made of corn gluten, alfalfa, cottonseed, or soybean. Most supply nitrogen and potassium, but soybean meal provides nitrogen and phosphorus.When initially spread they can cause an increase in ammonia within the soil and burn seeds, it is recommended to use these after plants have developed, to ensure crop success.
[4] Other ARS studies have found that algae used to capture nitrogen and phosphorus runoff from agricultural fields can not only prevent water contamination of these nutrients, but also can be used as an organic fertilizer. ARS scientists originally developed the "algal turf scrubber" to reduce nutrient runoff and increase quality of water flowing into streams, rivers, and lakes. They found that this nutrient-rich algae, once dried, can be applied to cucumber and corn seedlings and result in growth comparable to that seen using synthetic fertilizers
[5] Ash produced by plant combustion is also an important K fertilizer.
