摘要
为提高烤烟及其套种青稞的产值量,确定青稞的最佳播种量,采用随机区组试验,研究了在烟株封顶后上部烟叶留6片时,进行烤烟套种青稞种植模式,青稞播种量为45 kg/hm^2、75 kg/hm^2、105 kg/hm^2、135 kg/hm^24个不同播种量对2种作物产值量的影响。结果表明:青稞播种量105 kg/hm^2的综合表现最好,比最差的播种量45 kg/hm^2的烤烟产量和产值分别增长0.78%、5.04%,青稞产量产值分别增长16.79%、16.79%。
In order to improve the output value of flue-cured tobacco intercropping barley and ensure the suitable barley seeding rate, randomized trials were carried out in this paper. Intercropping of flue-cured tobacco and barley cultivation mode was carried out with barley sowing rate of 45 kg/hm^2, 75 kg/hm^2, 105 kg/hm^2, and 135 kg/hm^2. The results showed that the comprehensive performance of 105 kg/hm^2 was the best, 0.78% and 5.04% higher in output and output value of flue-cured tobacco and 16.79% and 16.79% higher in output and output value of barley of sowing rate of 45 kg/hm^2.
