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 view of the problems such as poor sowing quality and unreasonable fertilizer operation in wheat production, combined with the high-yielding wheat production in the Ministry of Agriculture, we experimented and demonstrated the integrated planting, soil testing and formula fertilization, nitrogen fertilization, integrated control of pests and diseases High Yield Cultivation Techniques. The results showed that the average number of effective panicles per hectare in experiment field was 6.983 million spikes, the average number of spike grains was 25.1, the average grain weight was 44.4 g, and the average yield was 7 763.1 kg / hm2, yielding 7 957.95 kg / hm2 of Hubei Province Wheat high yield record. The reason for the high yield is to improve the sowing quality, improve the application mode of nitrogen fertilizer, and coordinate the three elements of production.
