烤烟漂浮式育苗不同播种期对烟叶产质量的影响

Effect of Different Sowing Time on Tobacco Leaf's Yield and Quality in Floating Nursery of Flue-cured Tobacco

通过对云烟87设立不同播种期小区对比试验,探讨其对烟叶产量、质量的影响。结果表明:在相同条件下,不同播种期对烟株的农艺性状、生育期影响不大,但对烤烟的烟苗素质、产量、质量影响较大,耒阳烟区以12月25、28日播种的烟株产值效益最佳,过早或过迟会使烟叶的产值和品质受影响。

A comparative test of different sowing time was set up to explore its impact on tobacco yield and quality of Yunyan 87.The results showed that under the same conditions, different sowing time had little effect on agronomic traits and growth period, but it had greater impact on the quality and the yield of tobacco seedings. In Leiyang tobacco growing areas,it has the most economic benefits when the sowing time was on the December 25th or 28th ,Too early or too late would effect the output value and product value.
