小麦精密播种机械化技术是指用机械将一定数量的小麦种籽按照规范化要求的位置(行距、粒距、深度)播入土壤的技术。该技术旨在将传统的“大肥、大水、大播量”的高产栽培技术改变为“足肥、足水、小播量”的更高产栽培技术。其实质是在土壤、水肥条件好的高产地块上,通过降低播量,处理好群体与个体发育的矛盾,改善群体内有效分蘖的光照和营养条件,实现成穗率高,单株穗多、粒多、籽粒饱满,从而达到更高产的目的。
Wheat precision sowing mechanization technology refers to the use of machinery to a certain number of wheat seeds in accordance with the requirements of the standardized position (spacing, grain distance, depth) into the soil technology. The technology aims to change the traditional high-yielding cultivation techniques of “big fat, big water and big seeding amount” into a higher-yielding cultivation technique of “full fertilizer, enough water and small sowing”. Its essence is in the soil, water and fertilizer conditions of good high-yield plots, by reducing the sowing, handling contradictions between groups and individuals to improve the effective tillering group of light and nutritional conditions, to achieve high spike rate per spike , More grain, full grain, so as to achieve the purpose of higher yield.
