Description

Technical Field

[0001] This utility model discloses the field of irrigation equipment technology, and in particular relates to a towable intelligent integrated head system. Background Technology

[0002] Drip irrigation is a method of watering crops according to their water requirements. It uses a pipeline system and emitters installed on capillary tubes to deliver water and nutrients to the crop root zone drop by drop, evenly and slowly. Drip irrigation combines full-pipeline water delivery with localized micro-irrigation, minimizing water leakage and loss. Simultaneously, because it can supply the crop root zone with water in a timely manner, eliminating the problem of water loss from surrounding areas, it greatly improves water use efficiency. Drip irrigation can be easily combined with fertilization; fertilizer is dissolved and injected into the irrigation system. Since the fertilizer and irrigation water are combined, the nutrients are directly and evenly applied to the crop root layer, truly achieving synchronized water and fertilizer application, greatly improving the effective utilization rate of fertilizer. Furthermore, because it is a small-scale, localized, micro-irrigation system, water and fertilizer leakage is minimal, thus saving fertilizer application and reducing pollution.
