单粒精播模式下不同种衣剂包膜对玉米新品种吉单50出苗率和产量的影响

Effects of Different Seed Coating Covered Treatments on Emergence Rate and Yield of Jidan 50 under Single-Seed Precision Sowing

单粒精量播种正逐渐成为我国玉米生产发展的一项重要技术。针对玉米新品种吉单50的单粒精播技术,利用23种不同的种子包衣剂处理,分析其对吉单50单粒点播条件下田间出苗率和产量的影响。结果表明,不同种子处理对吉单50的出苗率和产量影响不同,其中种衣剂满适金和锐胜配合使用吉单50出苗率较对照提高7.19%,产量提高14.93%,显著提高了吉单50的种子出苗率和产量,建议在单粒精播生产上优先使用。

Single-seed precision sowing of maize is becoming an important technique for production development in our country. This study is aiming at to study the single-seed precision sowing technology on a new maize variety Jidan 50. Twenty-three different kinds of seed coating were used in this study, and then their effects on emergence rate and yield of Jidan 50 under single-seed precision sowing were analyzed. The results showed that the emergence rate and yield of Jidan 50 were varied under different treatments. Compared with the control, cooperative use of manshijin and ruishengfor Jidan 50 improved the germination rate and yield significantly by 7.19% and 14.93% ,respectively. So it was suggested that manshijin and ruisheng should have priority to be used in the production of single-seed precision sowing.
