摘要: 为进一步挖掘油用亚麻品种‘坝选三号’增产潜力,以高产栽培试验获得试验数据为基础,运用相关分析、回归分析、通径分析原理,分析了影响油用亚麻产量最关键的4个因素(单位面积株数、单株果数、果粒数、千粒重)对产量效应。结果表明,千粒重与产量相关系数最高为0.6549,达极显著水平,直接通径系数为0.466987;其次为单株果数与产量相关系数为0.42873,达显著水平,直接通径系数为0.479035;单位面积收获株数、果粒数与产量相关性不显著,直接通径系数分别为0.38956和-0.14038。提高油用亚麻品种‘坝选三号’产量要围绕增加千粒重和单株果数来制定相应栽培技术措施。从肥水调控、白粉病防治、防止倒伏、适时早收等方面提出了具体技术方案。

Abstract: To improve the yield of‘Ba-xuan 3’, the paper based on test data, using the correlation analysis, regression analysis and path analysis principle to analyze the key factor affecting production in four, including plants number per unit area, capsules per plant, fruits number and 1000-grain weight. The results showed that the between 1000-grain weight and yield were the highest, reached extremely significant level of 0.6549, the direct path coefficient was 0.466987, followed by correlation coefficient between capsules per plant and yield, which was 0.42873, also reached significant level, and the direct path coefficient was 0.479035. The correlation did not reach significant level between plants number per unit area, fruits number and yield, the direct path coefficient were 0.38956 and - 0.14038. To improve yield of‘Baxuan 3’, we should formulate cultivation technique measures around 1000- grain weight and capsules per plant. We proposed concrete technical scheme of water control, prevention and control of powdery mildew, prevent lodging, timely early harvest.
