In recent years, the sales of Agaricus bisporus are expected to increase year by year. With the abundant crop stalks in the North, the development of Agaricus bisporus production in rural areas is a very good way to increase income. However, the instability of the production of Agaricus bisporus has restricted the development of this industry. Therefore, to make the industry bigger and bigger, we must solve the technical problems of high quality and high yield of Agaricus bisporus.
Selecting high-quality strains and selecting high-quality strains is the key to achieving the high quality and high yield of Agaricus bisporus. High-quality strains have high purity, strong growth potential, and moderate age of bacteria, and are free of viruses, bacteria, and bacteria. When selecting strains, it is necessary to understand whether the growth characteristics of strains are adapted to local cultivation. Whether or not the strain manufacturer is manufactured according to the strain production procedures prescribed by the state, the most critical point is to look at the growth potential of strains, whether they are contaminated, and whether they are subject to pests. Infringement and storage time. The appropriate bacterial strain should be about 40 days.
Scientific preparation of culture materials Scientifically and rationally preparing culture materials is the basis for achieving high quality and high yield of Agaricus bisporus. The production should be based on the local cultivation conditions and the characteristics of raw materials, scientific choice of main and auxiliary materials, a reasonable ratio, to maximize the supply of nutrients for the growth of Agaricus bisporus. In general, when the output per square meter exceeds 15 kg, the input of wheat straw should be 32.5 to 40 kg per square meter. Should choose fresh, clean, high carbon and nitrogen content, light pests and contain viruses, bacteria, bacteria and less raw materials. Manure should be selected from animal manure or organic biological fertilizers, and nitrogen fertilizer should be avoided as much as possible with chemical fertilizers.
Recommended two formulations (per square meter of material): First, 30 kg of wheat straw, 10 kg of dry chicken manure, 1 kg of superphosphate, 1 kg of plaster, 2 kg of lime; the second is 20 kg of cotton seed shells, dry cow dung 15 Kg, cake fat 2 kg, superphosphate 2 kg, plaster 1 kg, lime 2 kg.
The culture medium is fully fermented. The prepared culture medium should be completely fermented, thoroughly cooked, uniform, no odor, no insects, no impurities, and no virus. The nitrogen content of the culture material is about 1.4%, and the ratio of carbon to nitrogen is about 21:1. About 7.3. The moisture content of the pre-wet raw material should be sufficient to do wet and dry.
The mixing of main materials and auxiliary materials should be uniform, and a layer of grass-type excrement-type pile-building mode should be eliminated. The cultivation material can be built into a growing bar, which is about 1.6 meters wide and about 1.5 meters high. The middle hole in the stack is oxygenated to minimize the anaerobic layer. Turn piles in time to minimize anaerobic fermentation time. During the secondary fermentation, the operating procedures of heating, maintaining temperature, cooling and ventilation must be strictly observed to ensure the quality of secondary fermentation.
Reasonable preparation of earth-covering materials for earth-covered materials not only affects the yield of Agaricus bisporus but also affects its quality. High-quality earth-covering materials should have good air permeability, strong water-holding capacity, proper nutrition, and no pests, viruses, bacteria, or bacteria. It is best to choose loam or loamy soil with light pests and diseases. Will choose a good soil exposed to sunlight for 3 days, and then add appropriate amount of wheat bran in the soil, fermented cow dung, etc., and then add lime, fungicides, insecticides, piled stuffy and go to bed after 3 days.
Fat contains more linoleic acid and less oleic acid. The effective ingredients of mushrooms can enhance the function of T lymphocytes, thereby improving the body's ability to resist various diseases. Mushrooms contain crude fiber, semi-rough fiber and lignin that are difficult for the human body to digest. It can maintain the water balance in the intestine, absorb excess cholesterol and sugar and expel it from the body. It can prevent constipation, bowel cancer, arteriosclerosis, diabetes, etc Both are very beneficial and have a significant effect on lowering blood pressure.
