Mixing ratio of Agaricus bisporus and precautions in production

A, Agaricus compost ratio. In 2003, Wangdu County vigorously developed the cultivation of Agaricus bisporus, and the Technical Bureau of Agriculture Bureau was responsible for the technical guidance of the Agaricus bisporus in the whole county. During the technical guidance in the countryside, I found four successful ratios of the Agaricus bisporus compost. That is, the main ingredients are: wheat straw, corn cob, corn stalk, cottonseed skin and wheat straw mixture. The thickness of raw materials for cultivation of Agaricus bisporus is generally about 20 centimeters. It is calculated according to the amount of material used per 100 square meters, and the proportion of main ingredients and accessories. The proportions of the above four composts were all tested by demonstration households and averaged about 20 pounds per square meter. Second, the production schedule of Agaricus bisporus. The production schedule of some successful cultivation of mushroom mushroom farmers in Nangangzi Village is as follows: Date Work Arrangement Contents and Requirements June-July Pre-stocking Preparation of various raw materials and accessories July 26-29 Pre-wet Ingredients Eating enough water July On the 29th to the 31st, the stack height is 1.5, and the width is 2 meters. The length is not limited. The first tumbling on August 5-7 is no more than 80 degrees Celsius. The positions are changed from top to bottom and mixed with water. For the second time on August 11-18, it will be the same as the previous one. On August 16-23, the third time I turned the same as above, I didn't need to add water. For the fourth time on August 20-27, it turned dark and dark brown. Before August 15th, the mushroom shed was ready to be built and turned over to the sun, with a drip film. From August 25 to 27, raw materials were sterilized in the shed and exterminated. The planting temperature was below 30°C on August 28-September 2. On September 11-15, the bacteria administration ventilated and sprayed water to prevent germs and insect pests. On September 12-16, when the soil is full or the soil is about to fill up, do not sifted and the land should not exceed 3 cm. October 1-6 Sunrise mushroom management attention to spray ventilation. After November 15 to 25, when the autumn oyster mushrooms finished no mushrooms, the bed was cleaned and closed. In the second year of March, after the mushroom was frozen in management, 1% lime water was sprayed per square meter. After the mushroom buds were sprayed, the amount of water spray was increased. Mushrooms end in early June When the temperature is higher than 25°C, the Agaricus bisporus ceases to grow. Third, pay attention to the production of Agaricus bisporus 1, preparation of wheat straw, corn stalks can not be rotted metamorphism, cow dung as possible dried, the smaller the better, to prevent the production of mold. 2, pre-wet, wheat straw sprinkled with white ash, eat enough water: white ash can damage the waxy straw wheat layer, in order to ensure the full fermentation of wheat straw. 3, when building a heap, the straw is laid at the bottom of the 20-25 cm, then, first add cow dung, and then add accessories to prevent all infiltration of accessories. 4. After the reactor is built, the reactor temperature is preferably between 68-78°C (on the 7th day after the reactor is built in Nangangzi Village, the reactor temperature is generally 75°C) The reactor temperature should not be greater than 80°C, and the water temperature greater than 80°C should be reduced. , Cover plastic sheets less than 65 °C warming. 5, turn the heap must be turned, the lower turn to the top, the middle turn to the outside. 6, mushroom shed preparation, it is best not more than three consecutive years of mushroom shed, culture materials must be done before entering the shed pest killing work. 7. Sow 2 bottles of 500 ml bacteria bottles per square meter of material surface. The strains should be diced into peanuts, not too small. Generally, sowing can be adopted. The three-dimensional structure of the support can be adopted to make full use of the space. When the humidity of the material is squeezed by hand, it is advisable to have water in the hand but not to drip. 8. During the period of germination, the “passing hall” was passed around at night and the grass was blocked during the day. If the material is dry, one percent of lime water may be sprayed properly. The humidity of the material surface shall be maintained at 25-26°C and must not be greater than 30°C. If any mucilages such as mucor or gypseous mould are found, cover with phosphate fertilizer to prevent Expand the infection. Pay attention to the prevention and treatment of mites, spider mites, available aluminum phosphide smoked shed, for oysters, oysters, etc., can use fried wheat bran mixed pesticides to prevent hazards; for fly, mosquitoes, available cloth stained with dichlorvos hanging in the shed to see the light control . 9, cover the soil: the cover soil mixed with wheat bran, wheat bran must use one percent lime water in advance soak for 3 days. Cover soil 2.5-3 cm thick, thin thin skin mushroom easy to open umbrella; too thick is too late mushroom, easy to big mushrooms, land mushroom. The soil's humidity is formed into blocks by holding soil, and the watermark on the hand is appropriate. 10, mushroom management: When the cover soil 13-16 days or so, poke the soil layer to see the mycelium in the soil from the original villous thicken line of metothecin, began to spray mushroom water, generally every square meter water spray 1 - About 2 pounds, spray water 3-4 times in 2 days. When the mushroom bud grows to a large amount of soy beans, the mushroom water is sprayed. At this time, water should be sprayed more, the air is ventilated, and the spray head is upward. Do not spray the mushrooms to death. The amount of water is preferably a combination of bauxite and cracks. There are many mushrooms on the bed, if the air is dry, spray water can be maintained; water can also be sprayed on the wall or aisle to maintain the humidity inside the shed. After October 20th, when the temperature of the greenhouse is 16°C, it should be sprayed with little water; on sunny afternoons, warm water should be sprayed; when the water is sprayed, the air should be ventilated; after 1 hour, the air outlet should be closed and the air outlet should be closed at night.

 Some traditional Chinese medicines are processed from insects. These kind of insects have high medicinal value, and we collect them when they are dead and use the medicinal way to process the whole body. They also plan an important role in traditional Chinese medicine area. Such as CICADAE PERIOSTRACUM and SCORPIO.
