There are many ways to quickly increase efficiency in farmyard fertilizers, and the effect is obvious and worthy of respect. Here are some commonly used methods for reference.
The method of adding fresh soybean milk to fresh cow dung: Add 2.5 kg of soy milk per 100 kg of fresh cow dung, mix it evenly in the cylinder, and seal it for 3-6 days at an air temperature of 25°C. The fertilizer is more effective than the same amount of ammonia. Pay attention to the application of water 2-3 times.
Calcium superphosphate method is added to human urine: Add 5 kg of superphosphate per 100 kg of human urine, mix well and store for 5-10 days. Through chemical reaction, the volatile ammonium carbonate in human excreta can be converted into stable ammonium phosphate, thereby effectively preventing the loss of nitrogen volatilization, increasing phosphorus in human excrement, and improving the quality of the fertilizer. Phosphorus ammonia effect.
Human urine is added with ferrous sulfate (green wolfberry) method: 500-600 grams of ferrous sulfate is added per 100 kilograms of human fecal urine, which can convert ammonium carbonate in human excrement into stable ammonium sulfate, which can be used to retain fertilizer. Deodorization prevents the loss of nitrogen from evaporation.
The method of adding salt in human excreta: Add 5 kg of superphosphate and 3 kg of salt per 100 kg of human excrement, and stir and evenly ferment for 10 days to increase the nitrogen content. Pay attention to water 2-3 times for pouring.
Plant ash mixed with superphosphate method: add 1 kg of superphosphate and add 2.5 kg of water and mix it well to allow it to naturally precipitate; add 3 kg of grass ash and add 5 kg of water to soak for 1 hour. Finally, separate the leachate and mix it with water. Kilogram spray, its effect can be comparable to potassium dihydrogen phosphate.
The method of compounding superphosphate in manure and compost: add 20% of superphosphate in compost and manure and mix it evenly and stack it for 20-25 days to prevent the loss of nitrogen in manure fertilizer and accelerate the decomposed process of manure composting. The effective phosphorus content increases the quality of manure and compost.
Ammonium bicarbonate was added to the compost: The crop stalks were cut into short sections of 5-10 cm length, ammonium bicarbonate was added at 1% of the total mass of the stalks, and a suitable amount of human excrement was added to build a heap and then covered with mud. Sealed, turned into efficient bio-potash fertilizer.
Titanium Pump For Sewage Treatment
Titanium pumps use the corrosion resistance, small specific gravity, high strength, and good high and low temperature comprehensive mechanical properties of titanium and titanium alloys when selecting materials for equipment manufacturing. Titanium is used at nodes such as flow parts, impellers and packing comprehensive seals. Or made of titanium alloy.
