摘　　要：为了实现豫东平原小麦主产区超高产栽培良种良法配套,充分发挥优质中强筋小麦新品种‘郑麦1860’的超高产潜力,运用裂区试验及统计分析方法,研究确定‘郑麦1860’在豫东平原小麦主产区超高产条件下适宜的播期播量指标。结果表明‘:郑麦1860’的适宜播期为10月10日-10月15日,最佳播期为10月15日;适宜播量为187.5~225.0 kg/hm^(2),最佳播量为225.0 kg/hm^(2)。最佳播期播量组合为10月15日与187.5 kg/hm^(2),折合单产12326 kg/hm^(2)。本项试验所取得的适宜播期播量技术指标,可在豫东平原小麦主产区‘郑麦1860’超高产栽培条件下推广应用。In order to achieve the matching of super high yield cultivation methods in the main wheat production area of the Eastern Henan Plain,and fully tap into the super high yield potential of the new highquality medium gluten wheat variety‘Zhengmai 1860’,split zone experiments and statistical analysis methods were used to study and determine the suitable sowing date and sowing quantity indicators for‘Zhengmai 1860’under the super high yield conditions in the main wheat production area of the Eastern Henan Plain.The results showed that the suitable sowing date for‘Zhengmai 1860’was from October 10th to October 15th,and the optimal sowing date was October 15th;the suitable sowing rate was 187.5-225.0 kg/hm^(2),and the optimal sowing rate was 225.0 kg/hm^(2).The optimal combination of sowing date and quantity was October 15th and 187.5 kg/hm^(2),which was equivalent to a yield of 12326 kg/hm^(2).The suitable sowing date and sowing quantity technical indicators obtained in this experiment can be promoted and applied under the super high yield cultivation conditions of‘Zhengmai 1860’in the main wheat production area of the Eastern Henan Plain.
