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,对旱地春小麦各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。
Agricultural research on mountain dryland has always been the key scientific research project of agricultural development in our province, especially the breeding of spring wheat in mountain dry land has been a weaker link. In this paper, based on the field test data, using statistical analysis methods, the main agronomic characters and yield of spring wheat in dryland were analyzed in detail and demonstrated in detail. The results showed that among the spring ecological indicators of spring wheat, Direct effect of the largest, followed by acres of spikes, spikelets and 1000-grain weight.
