摘　　要：为探讨小麦新品种皖垦麦0901的配套栽培技术,在沿淮淮北地区的安徽省龙亢农场采用裂区试验研究了播期和播量对皖垦麦0901产量及构成因素的影响。结果表明,不同播期和播量对皖垦麦0901产量构成因素及农艺性状影响显著,推迟播期降低了皖垦麦0901的成穗数、穗粒数和千粒重,降低了产量;增加播量能提高成穗数和产量,降低穗粒数和千粒重。根据试验结果,建议皖垦麦0901在沿淮淮北地区10月下旬播种以225 kg/hm2的播量、晚播条件下以300 kg/hm2的播量有助于提高其产量。The influences of sowing date and sowing rate on production and form factors of new wheat variety Wankenmai 0901 were studied, by split plot trial test in the Longkang farm in Huaibei Area of Anhui Province,for exploring cultivation techniques of new wheat variety Wankenmai 0901. The results showed that sowing date and sowing rate had significant effect on yield components and agronomic traits of Wankenmai 0901. Delayed sowing date reduced costs spike, grain number, grain weight and yield of Wankenmai 0901. Increasing sowing rate could improve ears development and production, and reduce grain number and grain weight. According to the test results, it was suggested that the sowing rate of Wankenmai 0901 with 225 kg/hm2 in Huaibei Region,and sowing rate of 300 kg/hm2 under late sowing conditions could improve the production.
