旱地春小麦数量性状与产量相关性研究

山旱地农业研究始终是我省农业发展的重点科研攻关项目，尤其是山旱地春小麦的品种选育，一直是较为薄弱的环节。本文基于田间试验资料，运用统计分析的方法，对旱地春小麦主要农艺性状与产量间进行了较为详细的相关性分析和论证，得出旱地春小麦各生态选育指标中，以株高对产量的直接效应最大，其次为亩穗数，小穗数和千粒重。

Study on the Relativity of Quantity Properties and Output of Spring Wheat for Rainfed Farmland

The reaserch about mountainous - dry region agriculture is the major scientific reaserch project of Qinghai province. Breeding of spring wheat variety to mountainous-dry region is weak link all along. According to the date acquired from field experiment and using staticstical analysis methed, we engage in intenelated analysis and demonstration in detail to the relation of agricultural character and output. It indicates that the effective of plant hight to output is most obvious. Apart from it, the ear quantity per mu, small ear quartity and the weight per thousand grain also have effective to output.
