摘　　要：针对目前小麦生产中存在的播种质量差、肥料运筹不合理等问题,结合农业部小麦高产创建活动,在鄂北岗地试验示范了规范化播种、测土配方施肥、氮肥后移和病虫害统防统治集成高产栽培技术。结果表明,试验示范田每公顷有效穗数平均为698.3万穗,穗粒数平均为25.1粒,千粒重平均为44.4 g,平均单产7 763.1 kg/hm2,创造出了7 957.95 kg/hm2的湖北省小麦高产记录。高产成因为提高了播种质量,改善了氮肥运用方式,产量三要素协调。In order to solve the problems of poor sowing quality and improper patterns of fertilizer application commonly existed in wheat production in Hubei province,combining the construction of high-yield wheat held by the ministry of agriculture,integrated high-yield culture techniques including standardized sowing,soil testing and formulated fertilization,postponing N application and integrated prevention and control of diseases and pest was studied in highland area of Northern Hubei province.The results showed that an average grain number was 698.3 × 104 spikes per hectare,an average grain number per spike was 25.1 and the average 1000-grain weight was 44.4 g.The average yield per unit was 7 763.1 kg/hm2,creating a new record of high-yield wheat in Hubei province.Improving the quality and the patterns of nitrogen fertilizer,coordinating three yield factors are the reasons for high-yield.
