In order to study consumption principle of cotton under drip irrigation with film, the paper adopted plot experiment, designed comprehensive combination tests combining four irrigation quotas (330 mm,390 mm,450 mm,510 mm) with three irrigation times (10 times, 13times, 16 times), analyzed cotton consumption characteristic of different irrigation quotas under drip irrigation with film, the results show that cotton consumption intensity in seeding period is between 1.39 and 2.15 mm/d; consumption intensity in bud period is 2.58 and 5.29 mm/d; consumption intensity in blooming period is 4.35 and 6.38 mm/d; and consumption intensity in boll opening period is 1.03 and 2.78 mm/d. Cotton consumption is closely related to irrigation quota under drip irrigation; under the same irrigation times, the larger the irrigation quota is, the larger the consumption, consumption modulus and consumption intensity in each stage are. The studied results will offer important basis for designing cotton irrigation system under drip irrigation with film.
