据禾谷类产量构成公式,春小麦的产量构成因素是单位土地面积上的穗数、穗粒数和粒重.为要创建一个高产稳产生态条件,应采用先进的栽培技术,协调群体穗、粒、重三因素均衡发展,使三者数值乘积为最大值.对春小麦的生产能力(源),运输能力(流)和贮藏能力(库)三者之间的关系,据以往的研究结果表明,如著重增加库(如大穗性选种),而不配置好源、流的??项性状,则库不充实,必然会降低千粒重和穗粒数,达不到增库目的;有了较丰富的源,若没有较强的流与发达的输导系统则生产的物质不能得到及时运输与储存,也不会获得理想的粒重.春小麦的生态生理一些指标,如土壤
According to the composition formula of cereal yield, the yield components of spring wheat is the number of spikes, grains per spike and grain weight per unit area of land.In order to create a high-yielding and stable ecological environment, advanced cultivation techniques should be adopted to coordinate the population spike, The three factors are balanced development, so that the three product of the maximum value of the product of spring wheat production capacity (source), transport capacity (flow) and storage capacity (library) the relationship between the three, according to previous studies have shown that such as Focus on increasing the library (such as large-spike selection), without the configuration of the source, the flow of traits, the library is not full, will inevitably reduce the 1000-grain weight and grains per spike, up less than the purpose of increasing the library; with more abundant Of the source, if there is no strong flow and the development of the guidance system, the production of materials can not be timely transportation and storage, will not get the ideal grain weight.Ecological and physiological indicators of spring wheat, such as soil
