Carbon and nitrogen ratio of edible mushroom cultivation materials

Carbon and nitrogen ratio of edible mushroom cultivation materials

In the process of treating edible fungi cultivation materials by using the golden treasure fermentation agent, the microorganisms in the culture materials decompose the carbohydrates, and part of the generated energy is used for the growth and reproduction of the microorganisms themselves, and part is released as heat energy. During this process, nitrogen is converted into bacterial proteins and remains. This bacteria is an important nutrient source for mushrooms. Due to carbon reduction and nitrogen residue, the carbon-nitrogen ratio decreased during the process of composting. The amount of carbon that can be assimilated by the functional microorganisms of the golden baby starter during functional microbial fermentation of the golden baby starter is roughly 30% of the total carbon content of the compost; and assimilation of these carbons requires the assimilation of 10% of the carbon content. Nitrogen. If 100 kg of carbon is contained in the compost, microorganisms can only assimilate 30 kg and also need 3 kg of nitrogen. Otherwise, the assimilation of microorganisms cannot proceed smoothly. The ratio of carbon to nitrogen in the initial compost should be 30 to 35:1, with 33:1 being the best. The proportion of mushroom compost and the amount of urea added should be strictly in accordance with this requirement. If there is insufficient nitrogen fertilizer, it will obviously affect the yield of mushrooms; if too much nitrogen fertilizer, it will not only cause waste, but also cause difficulty in fruiting due to the imbalance of carbon and nitrogen ratio. In a suitable range, the nitrogen content of the compost has a positive correlation with the yield.
