In the course of the growth of straw mushroom, appropriate measures can be taken to achieve high quality yield. Its specific approach is: First and second inoculation Adopting secondary vaccination measures will help the straw mushroom increase production. The mycelial growth rate of straw mushroom is too fast, and it is extremely easy to age, resulting in a weakened viability, and it is not possible to effectively use the nutrients in the cultivation material to continue mushrooming. After the first tidal mushroom is harvested, it is planted on the surface of the oyster mushroom and wetted with lime water. The pH of the cultivating material is adjusted to 8 to 9, and the strain is then spread on the surface of the material. After sowing, it is covered with a thin layer of fermented material. Culture material. Can also be in the first and second tidal mushroom harvest, turn the block over, turn the bottom layer of culture material to the surface, spray 1% of lime water to replenish water, adjust the pH, and then the surface of the second inoculation, the inoculum volume is 2 to 3%, generally about 30%. Using straw to cultivate straw mushrooms, four days after the sowing of grasses, strains can be placed in gaps in the grass layers for secondary inoculation. The inoculum size is about 20% of the first dose. In this way, when the first tidal mushroom is harvested, the second-inoculated strain can be decomposed from the haystack, accumulate nutrients and continue mushrooming. Second, adjust the pH During the growth process of straw mushroom, it will consume a large amount of nutrients in the culture material, resulting in metabolites, in which organic acid can increase the acidity of the culture material and affect the normal recovery of the mushroom mycelium and continue mushrooming. After the first tidal mushroom is harvested, supplementing with some nutrient solution and adjusting the culture material to be alkaline, can promote the recovery of hyphae, extend the period of mushroom harvesting, and increase the amount of mushroom production. 1, spraying 3% of lime water to the culture material, not only can make water, but also make the culture material is alkaline. 2. Spray 0.1% urea and bran water (100 kg of water plus 10 kg of bran, filter after boiling, and take 50 kg of filtrate plus 50 kg of fresh water). The amount of urea is 0.1 to 0.2%, and the amount of urea should not be too much, otherwise it will be easy to produce spores. 3. Apply dry cow dung and human urine. The dried cow dung was broken, 40% of human urine was added, and the mixture was homogenized. The mixture was pre-constructed for 1 day before being applied on the material surface after each harvest of a tidal mushroom. If you add some chicken or duck dung, the effect will be better. Third, the implementation of cover soil The straw mushroom covering soil can improve the moisturizing performance of the culture material and the adaptability to the humidity change, so that the mushroom body is hypertrophied and the dead mushroom is reduced, and the yield increase range is from 20 to 40%. The cover soil material can be used for vegetable garden soil (digging below 8 to 10 cm on the surface), and the thickness of the cover soil is generally 2 cm. Fourth, cover film After inoculated with straw mushroom, the film is covered with a film around the bacterial bed, which can increase and stabilize the temperature of the material, maintain the humidity, increase the carbon dioxide concentration in the microclimate around the material surface, promote the reproduction of related microorganisms, and promote the growth of the mushroom mycelium. Covering the film immediately after inoculation should be sooner rather than later. In order to prevent the positive film from sticking to the material surface and affecting the normal breathing of the bacteria, some straw or wheat straw soaked in lime water may be sprinkled on the material surface. After covering the film, check the material temperature. If the material temperature exceeds 40°C, remove the film in time. After the film is covered for 4 days, it is necessary to remove the film and ventilate it regularly or use a bamboo film to prevent the surface hyphae from being long and affect the extension of the hyphae into the material. When buds appear, the covered film should be peeled off in time, or the film should be raised to prevent the death of mushroom buds.
The Platewarmer uses minimum of energy due to the grid design of the heating element and provides a practical way to heat 3-12 plates in less time than it takes to cook a meal, leaving room in your oven for the cooking. To use the Plate Warmer, simply place up to 4 plates in each fold and switch on.
Electric Plate Warmers are thermostatically controlled to keep the plates at the ideal temperature to serve hot food whilst leaving the outer edges safe to handle and are a safe and easy alternative to heating up plates in the oven. The Electric Plate Warmer can be personalised with your own bespoke logo and/or design colour.
