The pump-injection-type fertilizer application device is convenient to operate and can be used as a special fertilizer application / injection device in agricultural irrigation systems or agricultural irrigation equipment such as center pivot sprinkling machines.
Description
technical field [0001] The invention relates to a fertilization device, in particular to a pump-injection fertilization device for circular sprinkler irrigation and fertilization operations, and belongs to the field of modern agricultural water-saving technology. Background technique [0002] The best technology recognized in the world today to improve the utilization rate of water and fertilizer resources is the integrated fertigation technology, which has become an important feature of modern intensive irrigation agriculture. Applying the sprinkler and micro-irrigation system to realize the coupling operation of irrigation and fertigation can precisely control the fertilization time, fertilization amount, fertilizer concentration and the ratio of nutrient elements, improve the utilization rate of water and fertilizer, and minimize the pollution to the environment. The traditional method of applying chemical fertilizers has low fertilization precision, and its fertilizer ut...
