本研究用模糊聚类方法,根据大豆冠层不同部位的粒重比例,对大豆品种的荚粒分布进行了分类。大豆冠层有明显的叶—荚对应关系,叶面积大的层次,粒多且大。对荚粒分布不同的品种,应当采取适当的措施,注意发挥对产量起主导作用的冠层部位的生产潜力。密度是调节主茎和分枝粒重分布的主要栽培措施。改良株型、提高叶片质量是改善大豆群体内部光合条件,充分发挥大豆整个冠层生产力的重要手段。
In this study, the fuzzy clustering method was used to classify the pod distribution of soybean cultivars according to the proportion of different parts of the soybean canopy. Soybean canopy has obvious leaf - pod correspondence, leaf area of large levels, more and more large grains. Appropriate measures should be taken for varieties with different distribution of pods and pay attention to exerting the production potential of the canopy that plays a leading role in yield. Density is the main cultivation measure that regulates the redistribution of main stem and branch. Improve the plant type and improve leaf quality is to improve photosynthetic conditions within the soybean population, give full play to the entire canopy soybean productivity an important means.
