Biogas fertilizer is divided into biogas residue and biogas slurry. A 10-m 3 biogas digester produces 4 tons of biogas residue and 6 tons of biogas slurry, which can supply 1,500 square meters of vegetables for the whole year. Biogas residue has high nutrient content, rich in organic matter and more humic acid, and plays an important role in improving the soil. Biogas residue is suitable for vegetable as base fertilizer or topdressing. Long-term use can make soil loose and fertility increase.
Biogas slag and biogas slurry are applied to the production of pollution-free vegetables. Note the following: Biogas residue is used for top dressing. The well-fermented biogas residue is an efficient and quick-improving organic fertilizer that can be used as a top-dressing fertilizer for various vegetables. The dressing is generally done with a planer hole and chasing the nest after chasing it. Tomatoes, cucumbers, eggplants, melons and other vegetables, the amount of fertilizer in acres once 1000 ~ 1500 kg.
Biogas slurry is used for top dressing. When biogas slurry is used for vegetable topdressing, the mixed biogas slurry proposed from the discharge chamber is generally used with a ratio of 1:2 water slurry liquid to furrow irrigation. After the chase, the biogas fertilizer sinks into the soil and is then filled with water. The amount of fertilizer on the mus is about 2000 kg, which can increase the leaf menu output by more than 30%.
Biogas slurry is used for vegetable top dressing. When the biogas slurry is topdressing on the foliage, the extracted biogas slurry must be filtered through the residue, and the biogas slurry has a water volume of 1:1, which can be sprayed directly on the foliage of various vegetables with a sprayer, and the spray amount per mu is 150~200. kilogram. About 20 hours after spraying, the water was sprayed again. The foliar application was sprayed once every 10 days, and the yield of vegetables was increased by about 30%.
Wastewater treatment is a process used to convert wastewater-which is water no longer needed or suitable for its most recent use-into an effluent that can be either returned to the water cycle with minimal environmental issues or reused. It takes an important part in improve our environment.
