摘　　要：在宁夏彭阳县城阳乡涝池村进行冬小麦全膜覆土穴播密度试验,试验设置了行距为10 cm、14 cm、18 cm、22 cm、26 cm 5个处理,对不同密度冬小麦生育期、农艺性状、产量等进行对比分析,试验结果表明：全膜覆土穴播冬小麦最适宜行距为14～18 cm,此时产量最高,达到6 481.5～6 666.7 kg/hm2.An experiment on the planting density of film-mulched hole sowing dryland winter wheat was conducted at Laochi village in Chengyang township in Pengyang county in Ningxia. In the experiment＇5 treatments were set with the hole spacing of i0 cm, 14 em, 18 cm, 22 cm and 26 cm respectively. A comparative analysis was made .on the growing periods, agronomic traits and yields of the winter wheat with different planting densities. The experiment result showed that the most suitable hole spacing for film-mulched hole sowing winter wheat was 14- 18 cm and with this the yield was the highest reaching 6 481.5 - 6 666.7 kg/hm^2.
