The invention relates to a
drip irrigation emitter for agricultural use. The
drip irrigation emitter consists of a material
bottle, a
bottle seat and a
burette. A
bottle mouth connector is arranged in the bottle seat; the bottle mouth of the material bottle faces downwards and is connected with the bottle mouth connector; the upper end of the
burette is connected with the upper part of the bottle seat; the
burette is communicated with the material bottle; a throttling device is arranged in a lateral wall at the upper end of the burette; the lower end of the burette extends towards the lower side of the bottle seat or extends obliquely downwards; the lower end of the burette is provided with a tapered arrow; an
aeration pipe is arranged in the material bottle; the opening of the upper end of the
aeration pipe is arranged at the upper part of the material bottle; and the lower end of the
aeration pipe is connected in the bottle seat. The burette is inserted into the soil near a
crop root system, the bottle mouth connector is arranged above the soil, the material bottle is filled with water or
nutrient fluid, the material bottle is reversed and then connected with the bottle mouth connector, and the water or
nutrient fluid flows along the burette to the
crop root system. The
drip irrigation emitter can reduce the
humidity in a big-arch shelter and prevent the
prevalence of
mycosis; and meanwhile, due to the adoption of a
caliber adapter, bottle bodies with different calibers can be used as material bottles, therefore, waste and old bottles can be made full use of and the cost is reduced.
