The invention relates to the farmland water conservancy field, in particular to a spraying and dripping irrigating system for fruit trees. The spraying and dripping irrigating system mainly comprises a water source, a front hub, a trunk tube, a dry tube, a spraying and dripping irrigating branch tube, a spray head and a dripping head, wherein the front hub mainly comprises a water pump, a fertilizer applying tank, a filter, a control valve and a pressure meter; the trunk tube is communicated with the dry tube; a water outlet pile is further arranged on the dry tube; water in the dry tube is filtered and then conveyed to the ground branch tube through the water outlet pile; the control valve is arranged at the connecting part between the water outlet pile and the ground branch tube; a three-phase valve is arranged on the upstream of the branch tube. The spraying and dripping irrigating system is reasonable in design, simple in structure, beneficial to irrigation and fertilization, capable of regulating the field microclimate, suitable for irrigating in a frozen period, and not prone to salt accumulation. Compared with the prior art, the spraying and dripping irrigating system is simple and convenient to operate, is economical and practical, is more suitable for practical production needs and is capable of further improving the water-saving efficiency of dripping irrigation.
