小麦产量高低,为品种基因型、自然生态因子和人工生态因子所综合制约。根据自然生态因子的组合特征,定量分析一定生态区内自然生态因子组合对产量构成因素的效应和产量潜力,阐明主导因子或限制因子,可为小麦的遗传和栽培控制提出指标和依据。本文分析了广东省三个气候带自然生态因子——主要为气候生态因子对小麦产量构成因素的影响,探讨南亚热带小麦产量潜力,建立本区不同生育期品种群的产量预测方程,为小麦产量性状生态变异的原因和本区小麦生产发展提出评价和依据。
The level of wheat yield, for the variety of genotypes, natural ecological factors and artificial ecological factors combined constraints. According to the combination of natural ecological factors, the quantitative analysis of the effects of natural ecological factor combinations on the yield components and yield potential in a certain ecological zone, and the identification of the dominant or limiting factors can provide the index and basis for the genetic and cultivated control of wheat. This paper analyzes the natural ecological factors of three climatic zones in Guangdong Province, mainly the impact of climatic ecological factors on the yield components of wheat, discusses the yield potential of the south subtropical wheat and establishes the yield prediction equation of the breed population at different growth stages in this area, The reason of ecotype variation of characters and evaluation and basis of wheat production in this area.
