Description

Biogas slurry irrigation nozzle and irrigation assembly Technical Field The invention relates to the field of agricultural appliances, in particular to a spray head for biogas slurry irrigation and an irrigation assembly. Background The biogas slurry is high-concentration organic wastewater obtained by anaerobic fermentation of organic matters such as livestock manure and the like, is a high-quality organic fertilizer resource, contains nutrient elements such as nitrogen, phosphorus, potassium and the like, contains rich organic matters, humic acid, amino acids, growth hormone and various trace elements, and causes a large number of germs, ova and weed seeds to suffocate in a long-term anaerobic fermentation environment. The biogas slurry is reasonably utilized in agricultural production, so that the yield and quality of agricultural products can be improved, the physical and chemical shape of soil can be improved, the soil fertility can be improved, the use amount of chemical fertilizers can be reduced, and the production cost can be reduced. Currently, in the application of biogas slurry, spray irrigation is the most commonly used method. The principle is that after the biogas slurry is pressurized by a water pump, the biogas slurry with a certain pressure is sprayed into the air by using a pipeline system and a spray head, and is scattered into tiny water drops to drop on plants and irrigated on the ground. The fertilizer has the advantages of high fertilizer application speed, uniform fertilizer application, labor saving and the like.
