First, the effect of application At present, the residue after fermentation in biogas digesters has been widely and comprehensively used, such as: application in crop farming, improvement of soil, edible fungi, fish breeding, pig rearing, prevention and control of crop pests and diseases, and soaking. The use of biogas digesters for fruit cultivation has the following three benefits: 1, increase production and improve quality. Biogas fermentation residue as fertilizer, has been used in rice, corn, peanuts, sugar cane, watermelon, loquat, Shatian You, citrus, bitter gourd and other crops, crops can make the average increase of 10% to 30%. In the aspect of fruit planting, the biogas fertilizer cultivates orange luxuriant tree, dark green leaves, significantly reduced pests and diseases, and pure fruit taste, which can increase production by 20% to 30% compared to the use of chemical fertilizers. Citrus liquid sprayed biogas slurry can increase the yield, effectively improve the ability of fruit trees to resist cold and prevent frost, increase the fruit setting rate at the same time, prevent and treat diseases and insect pests, and reduce the dosage of pesticides and chemical fertilizers. Shatianyou used biogas fertilizer, the acidity decreased, and the edible rate and sugar content of the pulp increased obviously. The use of biogas fertilizer to grow watermelon, compared with chemical fertilizer, 3000 kg of Mushi biogas fertilizer can increase production of about 360 kg, the difference is extremely significant, while the sweetness of watermelon is improved. The melon field is used continuously for 3 years of biogas fertilizer, which can effectively control the watermelon wilt disease; Rice The use of biogas fertilizer as base fertilizer can replace 50% of chemical fertilizer per 2000kg of applied fertilizer, can increase production by 7%, and can only apply biogas fertilizer of 8000kg/mu in sugarcane, compared with single fertilizer, it can increase production by 21.9% and average plant height by 9.02. %. 2, improve the soil. The long-term use of biogas tank fertilizer can loosen the soil, which is conducive to the activity of soil microorganisms and the formation of soil aggregates, increasing the content of soil organic matter, enriching soil nutrients of nitrogen, phosphorus and potassium, and activating the trace elements and microorganisms in the soil. Practice has proved that biogas tank fertilizer is both a good organic fertilizer and a good soil conditioner. 3, prevention and control of pests and diseases. Biogas fermentation broth can be sprayed on the surface or soaked to achieve the purpose of preventing and controlling diseases and insect pests. In combination with certain chemical pesticides, it can reduce the amount of pesticides and has better effects than single application of chemical pesticides. Second, the application method 1, as fertilizer application. Mu slurry of 1500 to 2500 kg of biogas slurry can be applied directly when the field is wet, and it is necessary to use it in a drought when the ratio is 1:1 to prevent bad seed or burn seedlings. 2, as a basal deep application. Digester slag can be directly applied as basal fertilizer, and can also be mixed with turf soil and superphosphate (or phosphate rock), and the basal fertilizer can be used after stacking for 1 to 1.5 months. The mixing ratio is 10:10:1. After application, the cover soil is 5 to 10 cm thick. 3, for fertilizer spraying foliar. The biogas digester liquid with normal gas production for more than 1 month can be sprayed after being clarified and filtered with double gauze. The purpose of filtration is to prevent the sprayer from being blocked. Spraying concentration should be based on the concentration of biogas slurry, crop time, season, and temperature, the principle is: 1 to 2 times the watered seedlings, high temperature watered 1 times, the temperature is low, the old leaves can not watered. Choose to spray once every 7-10 days in the sunny afternoon, and use 40 kg of biogas slurry. When sprayed, the back of the leaf is mainly used for absorption. Third, pay attention to matters 1, biogas residue can not be applied immediately after leaving the pool. The reduction of biogas residue is strong. If it is applied immediately after being discharged from the pond, it will compete with the crop for oxygen in the soil and affect the germination and root development of the seed, resulting in yellowing and wilting of the crop leaves. Therefore, after being discharged from the pond, it should generally be stored in the storage pit for 5-7 days before it is applied. If it is mixed with phosphate fertilizer at a ratio of 10:1 for 5-7 days, the effect will be better. 2, biogas can not be directly applied. When biogas slurry is used as top dressing, it is generally necessary to dilute water, especially if it is applied to seedlings, otherwise it will burn the crop. 3, biogas residue can not be applied topsoil. The application of biogas residue to dry land crops should be done by using a hole or trench, and then covering the soil. After applying the field to the paddy field, the plow is turned into the bottom layer. 4, can not be over-application. The application amount is generally less than that of ordinary pig manure, and if it is used in a large amount blindly, it will lead to crops being prolonged and causing a reduction in production. 5, can not be mixed with alkaline fertilizers such as grass ash, lime, etc., otherwise it will reduce the fertilizer effect.

Biogas digester fertilizers for fruits are effective
When the digester is added with raw materials such as pig manure and grass, after a period of fermentation, a refueling and swapping of residue and fertilizer water is called biogas tank fertilizer, also called biogas fermentation residue. As the biogas fermentation is carried out under gastight conditions, the loss of ammonia nitrogen is reduced, thus saving the nutrients and improving the fertilizer efficiency. Biogas digesters are rich in nutrients needed for a variety of crops, such as nitrogen, phosphorus, and potassium, as well as various biologically active substances such as Amino Acids, trace elements, plant growth stimulants, B vitamins, and certain substances. Some antibiotics, etc., are a quick and effective fertilizer. According to the measurement, a 10-m3 methane tank can produce 3 to 4 times of fertilizer each year, and an average of 18,000 kilograms of fertilizer can be produced. Individual biogas digesters can produce 2.5 to 30,000 kilograms of fertilizer each year.
