因地制宜,适量播种,有利于协调群个体生长及产量构成要素之间的关系,是百农207高产稳产的关键环节,但本麦区当前缺少有针对性的、科学规范的适宜播量指标对农民进行分类指导,也未见有关研究报道。本文分砂土、淤土、两合土3种土质,研究播量对百农207群个体及产量构成因素的影响,探讨本麦区不同土质类型高产田最佳适宜播量指标,为挖掘品种高产潜力、促进大面积小麦均衡增产提供理论依据。 According to local conditions, the appropriate amount of sowing is conducive to coordinating the growth of individual group and the relationship between yield components, is the key to high yield and high yield of Bainong 207. However, there is a lack of targeted and scientifically appropriate sowing indicators for farmers in this area. Classified guidance, nor the relevant research reports. This paper is divided into sand, silt soil, two combined soil three kinds of soil, the study of sowing on the individual hundred hundred and 207 groups of individuals and yield components, to explore the best yield sowing indicators of high yielding fields of different soil types in this area, High yield potential, and promote large-area wheat yield increase provide a theoretical basis.
