Effects of Different Mulching Modes on Cotton Growth and Soil Moisture in Tacheng Area Moisture Content
In order to learn the effects of different mulching widths of ultra-wide film and conventional film on the cotton different soil depths of water content,temperature,field growth,cotton dry mat-ter and yield differences in different periods.Two treatments were set up,treatment 1:laying with ultra-wide film,film width 4.4 m,1 film 12 rows of cotton plants;treatment 2:laying with conven-tional film,film width 2.02 m,1 film 6 rows of cotton plants.2 treatments were consistent in terms of density,row spacing(66 cm+10 cm)and field management.Results showed that ultra-wide film cotton in 20 cm,30 cm,40 cm,50 cm,60 cm soil layer average water content was lower than conven-tional film cotton;ultra-wide film cotton root layer average soil temperature during the whole life cycle was higher than conventional film cotton,ultra-wide film cotton average number of fruiting branches compared to the average number of fruiting branches of the conventional film more than 1.43,the average leaf area of a single plant was more than 747 mm2;ultra-wide film cotton in differ-ent parts of different periods of time,the dry matter weight of different parts of cotton in different periods was higher than that of cotton with conventional film;the yield of cotton with ultra-wide film increased by 39.21 kg/667 m2 compared with that of cotton with conventional film.
