本文对40个大麦品种的形态特性、机械性能和栽培措施与倒伏的关系进行了研究。结果表明,植株的株高,节间的长度和粗细,根冠比值等品种的形态指标,茎秆的组成成分和结构及栽培措施等都与倒伏有关。生产上只要选择良种,采用合理密植,合理施肥,就能既发挥个体和群体潜力,又能防止倒伏,以达到高产的目的。
In this paper, the morphological characteristics, mechanical properties and cultivation methods of 40 barley cultivars were studied. The results showed that the plant height, internode length and thickness, ratio of root to shoot and other varieties of morphological indicators, composition and structure of stalks and cultivation measures are related to lodging. As long as the selection of good seed production, the use of reasonable close planting, fertilization, will be able to both the potential of individuals and groups, but also to prevent lodging in order to achieve the purpose of high yield.
