Using waste of Pleurotus ostreatus and Pleurotus ostreatus as organic fertilizer

Edible mushroom bran is rich in organic matter and a variety of mineral elements. According to the examination and analysis of the soil and Fertilizer Institute of Henan Academy of Agricultural Sciences, total nitrogen: 1.95%, total phosphorus: 1.37%, total potassium: 1.75%, organic matter: 62.3%. Bacterial bran contains many trace elements such as calcium, phosphorus, sodium, copper and so on. Using bacterial bran as organic fertilizer can reduce the application amount of chemical fertilizers and pesticides and their residues in agricultural products, and improve the yield and quality of agricultural products. It provides a guarantee for the production of organic food. After the application of edible mushroom bran organic fertilizer in the soil, humus with good aeration and water storage capacity can be formed, which is of great significance to improve soil and improve soil fertility. In addition, some kinetin substances and enzymes are secreted during the growth of edible fungus mycelium, and these enzymes can decompose complex organic matter into nutrients that can be easily absorbed by plants. In Japan, the dilution of mycelium extract from edible mushroom bran is used to make plant hormone, which is sprayed on cucumber, tomato, eggplant, lentil, soybean and other crops, which can promote crop growth and increase yield. For example, when used in soybean crops, it can make soybean stems and leaves strong, enhance disease resistance, and increase by 2.6 times. In the experiment of adding beneficial biological bacteria or suitable bacterial preparation to waste bacterial bran in a variety of vegetable crops, it was found that the effect of microbial plus bacterial bran was the best, providing plant nutritional activity, reducing the cost of agricultural production, and significantly increasing the yield of crops. In addition, the configuration of organic nutrient soil with edible mushroom bran is also widely used in flowers. The cultivation of flowers such as camellia and orchids in nutritious soil with bacterial bran fertilizer can not only enhance the disease resistance of flowers, but also promote their quality, meet the needs of flower growth and development, and is a valuable resource instead of humus soil.
