摘　　要：本试验验采用不同油用亚麻品种,分析研究了播种期对产量及白粉病发病情况的影响,结果表明播种期对白粉病发病的影响不显著,适当提早播种能较大幅度地提高油用亚麻产量,是一项行之有效的丰产栽培技术。This paper analyzed the relationship of sowing time with the yield and the severity of powdery mildew, different oil flax varieties were investigated. The results showed that early sowing did not have an evident influence on powdery mildew but could increase the yield of flax significandy. Reasonable early sowing is an effective high -yield cultivation technique.
