摘　　要：为筛选适宜喀什地区的机采棉花种植模式,2019年在喀什地区疏勒县,开展了机采棉花不同种植模式对农艺性状及产量影响的试验。结果表明:除等行距模式(R2和R3)较宽窄行模式(R1和R4)的出苗期提前2天外,处理间的生育进程和生育期无差异;种植模式对棉花始果枝位及高度影响较小,对单铃重和衣分、脱叶率和吐絮率差异均不显著(P>0.05);种植模式对棉花产量影响显著,R1模式(一膜六行宽窄行)的籽棉产量和皮棉产量均最高,其籽棉产量分别较R2、R3和R4模式高9.00%、12.67%和9.11%。结合生产实际,一膜六行宽窄行(64 cm+12 cm)机采种植模式更适宜喀什地区。In order to select the suitable planting pattern of machine-picked cotton in Kashi region,a test of the effect of different planting patterns on agronomic characters and yield was carried out in Shule County,Kashi area in 2019.The results showed that:There was no difference in the fertility process and the fertility period between the treatments except that the emergence period of R1 and R4 was 2 days ahead of the emergence period of the wider narrow row pattern (R2 and R3)..The influence was little on the first fruit branch and the height of first fruit branch of cotton,There was no significant difference in single boll weight,ginning outturn,defoliation and floc rate (P >0.05),the impact of yield was significant.The Seed cotton yield and lint yield of R1 was the highest,9.00%,12.67% and 9.11% higher than that of R2,R3 and R4 respectively.Combined with the production practice,the machine-picked cotton of planting pattern of 6 rows wide and narrow rows of 64cm + 12cm was more suitable for Kashi area.
