摘　　要：小麦精播“三高”栽培技术的研究,依据了小麦的生物学原理,针对淮北小麦分蘖成穗、穗分 化、籽粒灌浆特征,从减少播量,降低基本苗,精细播种为突破口,通过一系列调控优化技术的实施, 提高群体质量,促进库容发育挖掘单株综合生产潜力,从而达到群体高质量,个体高素质,种植高效 益的“三高”目的,形成了完善的精播“三高”栽培体系。The paper is mainly on research of the “three high” accurate cultivation method of wheat. Based on the biological principle of wheat, and according to the characteristics of the formation of wheat tillers and ears, the differentiation of ears, milking of the grains, thus the quantity of the sowing, and the basic seedlings number is decreased, so the accurate sowing became the breakthrough. Through the application of a series of controlling optimization method, the population yield is enhanced, promoting the sink capacity to increase the comprehensive potential, thus the aim of “three high ” method is attained, which means high population yield, high individual quality and high benefit of cultivation. And a perfect cultivation system of the accurate “three high” cultivation system is formed.
