The invention relates to agricultural spraying operation wind field test equipment and a test method, belonging to the technical field of agriculture aviation. The test equipment comprises an unmanned helicopter for arranging a spraying system to be tested; the unmanned helicopter is arranged on a fixed platform which is arranged on a telescopic rod at the upmost front end of a hydraulic telescopic cylinder; a cylinder body of the hydraulic telescopic cylinder is arranged on a trolley with a roller; and at least three suspending ends are fixed on the periphery of the fixed platform and used for adjustable cable ropes fixed with the ground. The test equipment can be used indoors or outdoors; since the unmanned helicopter is completely positioned at the fixed position in the air during work, a relatively-stable wind field can be formed and credible test data can be acquired; in addition, the invention provides scientific base for researching spraying pesticide on a two-phase flow field through the unmanned heli
