建立合理的小麦群体结构,是充分利用光能和地力、提高单位面积产量的中心环节,为了指导生产实践,我们通过不同基本苗的田间试验,探讨群体与个体间的动态关系,并对成产因素的数量指标进行了初步分析。一、材料和方法本试验近三年在伊洛灌区东高、霞宫等基点进行。设计密度每亩基本苗为:1万、3万、6万、9万、12万、15万、18万、21万。
To establish a reasonable structure of wheat population is the central link of making full use of light energy and soil fertility and increasing yield per unit area. In order to guide the practice of production, we explore the dynamic relationship between groups and individuals through field experiments of different basic seedlings, The number of factors index conducted a preliminary analysis. First, materials and methods The experiment in the past three years in Irrigation Irrigation East, Xia Gong and other basis points. Design density of basic seedlings per acre: 10,000, 30,000, 60,000, 90,000, 120,000, 150,000, 180,000, 210,000.
