Organic manure is an organic natural fertilizer that is produced on the spot using various organic substances in the countryside. Its main source is human and animal excreta, plant residues and other substances. At present, in the vast rural areas, as the use of green manure, compost, and manure is becoming less and less, the manure produced by humans and pigs' urine has become the main organic fertilizer used by ordinary farmers. The specific approach is: to build a septic tank next to the pig shed and build a latrine on the septic tank. The squat pit of the toilet is directly connected to the septic tank, and the pigsty communicates with the septic tank, and the inside of the pig sirf is set to a shallow position. The pond is connected to the ditch. It is required that the floors, walls, toilets and pigsty floors of the septic tank must be constructed of cement, all of which require watertightness. Sweep the pigsty every morning, sweep swine manure into the shallow pond, rinse the shallow pond with about 10kg of water, and let the excrement flow into the pit with the water through the ditch. This will make the excrement of humans and animals in the air condition Next, after 1 - 1.5 months of maturity, it is desirable to take the pool of manure to the field application. When constructing a septic tank, it should be noted that the volume of the septic tank should not be less than 1.5 cubic meters, and the wall of the storage tank should be slightly higher than the ground. Because 4 households (including 2 adults and 2 children) are fed by a farmer, and 2 pigs are fed year after year, a fecal water meter is produced once a month. Each month, the pig’s excrement is approximately 0.7 cubic meters, and pigs are washed every day. In the shallow pond, 10 kilograms of water is used, and 0.3 cubic meters of water is used for a month. The sum of the two is roughly 1 cubic meter, plus some organic waste from farmers, and the remaining dung and dung from the last excrement water. It is suitable for 1.5 cubic meters. The length and width of the storage tank are each 1 meter and 1.5 meters deep. The wall of the septic tank is slightly higher than the ground, preventing the inflow of surface water. 1. Fecal urine should be stored for at least 1 month before being used for field application. 2. Most farm households have the habit of stirring up the bottom of the pool when they produce manure, and think that there is more nutrients in the manure. In fact, this is wrong. Most of the contained nutrients have entered the liquid after the excrement is excreted, and in addition to difficult-to-decompose organic matter, there are a large number of pathogens and parasite eggs excreted by humans and pigs. For other harmful substances, it takes a long period of time to kill the harmful substances. Usually, the bottom sediment is removed in about 3 months. Normally, it should not be stirred up. The excrement on the surface of the septic tank is due to lack of air stagnation, and it needs to be applied again after tanning. 3. Manure water is a more efficient fertilizer with more nitrogen, and it has good fertilizer effect on general crops. It is especially suitable for top-dressing vegetables, such as vegetables, mulberry, and hemp, which are used for harvesting leaves. The specific approach is to use the manure to irrigate the roots, splash the water, and irrigate the pond to raise the seedlings. 4. Due to the large amount of chlorine in the waste water, it is advisable to apply it less frequently when applying it to tobacco crops such as tobacco, potatoes, and sugar beets. 5. If larvae of wild green manure such as Artemisia spp., Eupatorium adenophorum, etc. are added to the septic tank, not only the insecticidal activity can be increased, but also the organic matter content in the waste water can be increased, and the volatilization loss of ammonia can be reduced.
