First, fertilization should be appropriate: the growth and development of fruiting bodies need to use nutrients in the culture material. Each batch of mushrooms needs to consume a larger portion of nutrients. Therefore, the most suitable supplementary period for fertilization of the bacteria bed is during the period from the time one batch of mushroom is harvested to the next batch of mushrooms, which is also known as the tidal period. In addition, the fruiting body has a certain absorption function to the outside nutrients during the young period, so it is necessary to fertilize it properly during the bud period.
Second, fertilizer should be used with reasonable or alternating: the growth of edible fungi, not only requires a lot of carbon, nitrogen, phosphorus, potassium and other elements, but also a certain amount of trace elements; In addition, cytokines, gibberellins and other growth hormone on food The growth and development of bacteria also have an important influence, so in the fertilization process, fertilizers should be used in a reasonable manner or used interchangeably.
Third, the fertilizer concentration should be appropriate: fertilizer concentration is too high, nutrients not only not absorbed by the mycelium, but will prevent the normal growth of mycelium; concentration is too low, it is difficult to play its due effect. In the commonly used fertilizers, the concentration of organic fertilizers is generally controlled at about 2%; the concentration of sugars is appropriate 0.1-0.3%; the concentration of urea should be controlled at 0.1-0.3%; the concentration of inorganic salts such as phosphorus, potassium, magnesium, etc. Should be between 0.05-0.1%; zinc, manganese, boron, molybdenum and other trace elements concentration can be between 0.02-0.05%, auxin concentration varies with the type, the general concentration of 0.5-5ppm.
