摘　　要：为了解不同播种方式和播量对稻茬小麦生产效益的影响,于2016-2018年度在湖北省随县农作物试验示范展示基地进行稻茬小麦不同播种方式和播量试验,分析不同播种方式和播量对稻茬小麦生长发育、抗逆性和产量的影响。结果表明,免耕机械条播用种量较小,小麦出苗率较高,生育进程较快,抗逆性较强;播种量与出苗率和抗逆性成负相关,与各时期茎蘖总数成正相关,与生育期不相关;免耕机械条播更适合鄂北地区稻茬麦生产,与160kg/hm^2的播量为最理想组合。In order to understand the effects of different sowing methods and sowing rates on the production efficiency of rice-stubble wheat,the effects of different sowing methods and sowing rates on the growth,development,stress resistance and yield of rice-stubble wheat were studied in the demonstration bases of crop experiments in Suixian County of Hubei Province from 2016 to 2018.The results showed that the characteristics of using no-tillage mechanical drilling was to require less seeds,higher emergence rate of wheat,faster growth process and stronger resistance;seeding rate was negatively correlated with emergence rate and resistance,positively correlated with the total number of tillers in each period,but not correlated with the growth period.No-tillage mechanical drilling was more suitable for rice-stubble wheat production in northern Hubei,and the most ideal sowing rate is 160 kg/hm^2.
