通过耕播一体化匀播和常规条播两种播种方式的10个播量试验,筛选出宁春50号适宜的播种方式和播种量。结果表明:耕播一体化匀播播种量在315.0~450.0 kg/hm~2时,比传统条播播种量337.5 kg/hm~2增产9.44%以上。其中处理6单产最高,为7 126.2 kg/hm~2,较处理8(CK)增产15.1%;其次为处理4,单产为7 069.35 kg/hm~2,投入、产出比最高。说明耕播一体化匀播播种方式可以在宁夏灌区推广,适宜播种量为315.0~450.0 kg/hm~2,节本增效显著。
Ten sowing experiments were conducted on both tillage and conventional sowing, and the suitable sowing methods and sowing rates were screened. The results showed that when sowing rate was 315.0 ~ 450.0 kg / hm ~ 2, yield was increased by 9.44% or more than that of 337.5 kg / hm ~ 2. Among them, the highest yield of treatment 6 was 7 126.2 kg / hm ~ 2, 15.1% higher than that of CK 8, followed by treatment 4 with a yield of 7 069.35 kg / hm ~ 2. The results showed that tillage and sowing integrated unifloral sowing method could be popularized in irrigated area of Ningxia. The suitable sowing rate was 315.0 ~ 450.0 kg / hm ~ 2.
