The invention discloses a Xinjiang cotton mulching film narrow coverage trickle micro-irrigation cultivation method. The method comprises the following steps of 1 pre-sowing preparation, 2 seed sowing, 3 pipeline arrangement, 4 intertillage, 5 watering, 6 chemical regulation, 7 fertilization, 8 pest control, 9 topping, 10 disleaving and 11 harvesting. The Xinjiang cotton mulching film narrow coverage trickle micro-irrigation cultivation method has the advantages that trickle micro-irrigation is adopted on irrigation, no drip irrigation zone is arranged, the problem that a weeding machine is affected by the drip irrigation zone is solved, on the basis of the mulching film narrow coverage and trickle micro-irrigation technology, by means of special cultivation means of increasing the weeding frequency in the machine and the like, and the purposes of water retention, temperature increase and weed control are achieved, so that the narrow mulching film coverage is lowered, the production risk is lowered, an original mulching film with the breadth being 2.05 m is replaced with three 30 cm or 40 cm narrow mulching films, the narrow mulching film input amount is 43.9-58.5% that of the wide mulching film, pollution of the PE mulching film and the irrigation zone to a cotton field is reduced, the purpose of cotton field clean production is achieved, and meanwhile the purposes of high yield and high efficiency of mulching film cultivation are achieved.
