Abstract: To explore sustainable sowing practices for corn in arid areas,corn was sown using four cultivation modes:(1)double ridge/mulching with plastic film/furrow sowing(DRMF),(2)double ridge/no mulching/furrow sowing(DRNF),(3)double ridge/mulching with plastic film/furrow sowing/intercropping with soybean(DRMFI),and (4)the ecological organic double ridge/no mulching/furrow sowing(EODRNF).The yield and agronomic traits of corn were compared under the different sowing modes.It was found that the growth period was shorter in the DRMF mode than in the DRNF mode.The yield of DRMF was significantly higher than the other modes.The yield of corn was in the order DRMF>EODRNF>DRNF>DRMFI.There was a significant difference between the row number and kernels per row between the DRWF and the DRNF.Soil sampling and analysis in spring and autumn showed that the content of alkali extractable and N in autumn was lower than in spring.The content of total P was higher in autumn than spring,while available P was lower in autumn.Significant differences in total P and available P occurred between treatments.Available K was lower in autumn than spring and there were significant differences between the treatments.

Key words: Corn, High yielding, Double ridge/mulching with plastic film/furrow sowing, Soil fertility, Sowing mode
