Techniques for cultivation of straw mushrooms using idle sheds
Filtration rod filters Equipments
Describe:
Filter rod filter equipment can be divided into: ceramic membrane filter rod, stainless steel strong magnetic rod filter, stainless steel titanium rod filter. In the process of industrial production, ceramic membrane filter rod is used to treat waste water, raw water and waste liquid. The waste water can reach the national discharge standard or recycle after passing through ceramic membrane filter.
Classification and applications:
The core component of ceramic membrane filter is ceramic filter rod. It uses acid-resistant ceramic particles or quartz, corundum sand and other raw materials as the main raw materials, and adds a small amount of inorganic binder and reinforcements to carry on scientific formulation. Grading, molding, film making and other processes from processing.
Titanium rod filter uses titanium powder sintered filter element, which is made of hollow filter rod by high temperature sintering of titanium metal powder by powder metallurgy method. It is widely used in the separation of liquid and solid in food, beverage, medicine and chemical industry. It is often used in coarse filtration or intermediate filtration. The filter element has the advantages of high temperature resistance, corrosion resistance, high mechanical strength, and the filter element can be reused repeatedly. Filter equipment housing material is 316l or 304 stainless steel.
Stainless steel strong magnetic rod filter has a magnetic rod with high quality stainless steel tube and high B value rare earth alloy neodymium boron. It is made by special manufacturing method and is used to gather the powder transported by liquid, slurry flow and air supply pipeline. The strong magnetic iron impurity in gas and other enterprise phase is widely used to remove iron from high temperature condensate and back water in power industry. Also used for fluid food filling line fine metal impurities removal to ensure food safety.

1 The soil in the treatment shed of the greenhouse should be sown and exposed to white. The soil was disinfected about 15 days before sowing and sprayed with 5% formaldehyde and 500-fold diluted phoxim. Then we do the earthwork, we have a width of 0.8 to 1 meters, a depth of about 0.1 meters, and a walkway width of 0.4 meters. Mushrooms and the soil on the walkway must be thoroughly irrigated, but appropriate amounts of manure and lime must be applied to the soil on the walkway to increase the nutrients and pH of the soil so that it can be used as a cover after sowing. After water infiltration, sprinkle the amount of lime of 100g/m2 on the surface of the soil. The roof is covered with haystacks to reduce the light in the shed.
2 The formula of the culture material is wheat straw 80% - 90%, lime 5%, bran 5% or decomposed manure 10%. Wheat straw needs to be soaked and softened. Dig a shallow pit near the cultivation shed. The inside of the pit is lined with a film of water leakage. Fill the pit with a layer of grass and spread the limestone. The material is pressed on several sticks and then poured into the pit to flood the surface. After soaking for about 2 days, remove the fodder, leach to clear water, mix in bran or manure, adjust pH 8 to 9, and the moisture content is 65% to 70%.
3 Spreading Seeding The prepared culture material is spread in mushroom pods, and the material thickness after proper compaction reaches about 20 cm, and the material surface is formed into a turtle shape with low middle height and four sides. Seeding by sowing sowing, suitable varieties for V35, V34, V23 straw, seeding rate of 8% to 10%, bacteria should be used in about 20 days of bacteria. Immediately after sowing, the soil was covered with a walkway and the soil thickness was about 3 cm.
4 During the period of germination and differentiation, management and control of temperature and humidity and proper ventilation were the main management tasks in this period. Keeping the shelf temperature at 32 to 35°C, the material temperature at 33 to 38°C, and the air humidity at around 80%, generally do not spray water to the material surface. After sowing for 2 days, it can be ventilated 1 to 2 times a day for about 15 minutes each time. Afterwards, the amount of ventilation increases as it grows. After 5 to 6 days of sowing, the hyphae can grow over the culture material and complete the germination. At this point should be sprayed about 30 °C 1% lime water, the light was raised to see the small print on the newspaper to induce the formation of primordia.
5 fruiting period and intermittent management sowing 7-10 days, the material surface appears white rice primordium. At this time, the temperature of the shelf should be kept at about 30°C, and the air humidity should be 90%. Do not spray water on the buds before the buttons. In order to avoid death of mushrooms, spray water should be sprayed with water of about 30°C. Ventilation should be based on the weather conditions. After the mushroom grows to oval, harvest it in time. After harvesting a tidal mushroom, it is cleaned and then sprayed with wheat bran pH8 to 9 to adjust pH and supplement nutrients. Wheat bran water is prepared by adding wheat bran to 10 times water, boiling for about 20 minutes, taking the filtrate, and diluting the filtrate with water in a ratio of 1:1. Generally, the second tidal mushroom can be collected in about 8 days. After two tidal mushrooms are collected, the materials should be cleaned and the site should be sorted out in order to prepare for the production of kang.
6 Problems that should be noted (1) Mycelial growth stage: Under the conditions of high temperature, high humidity, and poor ventilation, the hyphae tends to be long and does not extend into the material. The temperature and humidity of the culture material are too high, or the material pressure is too strong, and when the aging strain is used, hyphae tend to shrink. Once an abnormal phenomenon occurs, the cause should be identified and remedial measures should be taken promptly. (2) Growth stage of fruiting bodies: To prevent the occurrence of malformed mushrooms and dead mushrooms. In the case of poor ventilation, the coating on the top of the mushroom buds tends to appear circular nicks and become umbilicus mushrooms. When the temperature, humidity is too high and the ventilation is poor, the fruiting body will grow into a small, light, thin, early-open umbrella inferior mushroom due to its rapid growth. High temperature and humidity, poor ventilation, too large temperature difference, culture material is too loose or acid, spray water temperature is lower than 20 °C or higher than 40 °C, ventilation into the dry hot air, the use of aging and bacterial growth of bacteria, produce Severe diseases and insect pests can cause dead mushrooms.
7 The success of the cultivation of straw mushroom culture materials in the appropriate increase in the amount of lime and manure; in the differentiation period and after the mushrooms to spray 1%? 2% lime water; mushrooming period should pay attention to the coordination of temperature, humidity, and avoid Temperature damage. In the unused vegetable shed, wheat straw is added to the formula with a small amount of bran or manure, and the raw material is cultivated directly. The soil that is drenched with manure and lime water can make the transformation rate of wheat straw reach 30% to 40%.
Practice has shown that rotating mushrooms and vegetables in greenhouses can not only significantly increase economic efficiency, but also make full use of time, space, manpower, and material resources. Mushroom waste can also provide fertilizer for squat vegetables. More ideal planting patterns.
