Description

Technical Field

[0001] This utility model relates to the field of fertilizer spraying technology, specifically to an agricultural liquid fertilizer spraying device. Background Technology

[0002] In agricultural production, to ensure the survival rate and growth efficiency of crops, different fertilizers are applied to crops at different times. Therefore, spraying devices are needed to transfer the fertilizers and spray them onto the crops. Agricultural liquid fertilizers need to be sprayed in actual use, and different states of agricultural liquid fertilizers need to be sprayed to meet irrigation needs.

[0003] Currently, existing agricultural liquid fertilizers cannot effectively provide comprehensive fertilization, nor can they ensure that crops can absorb the fertilizer effectively. This leads to insufficient fertilizer absorption, resulting in crop wilting, death, or slow growth. Furthermore, most spraying equipment is wasteful, and over-fertilization can cause damage to crops. Therefore, corresponding technical solutions need to be designed to address these issues. Utility Model Content
