Embodiment 1
[0025] The main materials and tools in this embodiment are: cyanobacterial algae mud, environment-inducing materials, warm heap pools, flexible storage bags, straw curtains, moso bamboo, nylon nets, sunscreen nets, bamboo rakes, and the like.
[0026] Transformation process: After concentrating and dehydrating 500kg of fresh cyanobacteria, the water content of the algal mud is 90-95wt%, and the algal mud is directly added according to 0%, 0.1%, 0.3%, 0.5%, 1.0% and 1.5% of the quality of the algal mud or diluted 20 times with water. Spray and add environment-inducing materials, stir evenly, and then transport to a storage tank or flexible bag, and naturally avoid light and thermopile transformation, temperature 25-35 ℃, humidity 65-100g / m 3 , Under the air pressure of 1atm, it can be completely transformed in 3-5 days. There is no obvious algal odor, the algal mud turns black, and the surface has white mildew spots.
[0027] The composition of the environment-inducing material...
Embodiment 2
[0033] Application method 1: The transformed organic fertilizer prepared in Example 1 is directly diluted with water as an organic fertilizer, and is fed to catfish, crucian carp, and snail. Under continuous topdressing, the pH value of the water body floats between 6.9 and 7.8, and the snails grow well.
[0034] Application method 2: The transformed organic fertilizer prepared in Example 1 is directly diluted with water as an organic fertilizer, planted with Chlorophytum, Dripping Guanyin, turf, and water lilies, under continuous top dressing, the Chlorophytum leaves increased, the Dripping Guanyin leaves were light green, and the turf and the water lilies grew vigorously.
[0035] The algal mud organic fertilizer fertilizer effect components of the present invention are as follows:
[0036]
[0037] The fertilizer components of the algal mud organic fertilizer refer to the urban garbage agricultural control standards. The content of various heavy metals, the death rate of ...
