[目的]适应日照市烟草生产实际,满足工业需求,提高市场竞争力。[方法]在日照市莒县进行烤烟新品种小区对比试验及大区对比试验,筛选优良烤烟新品种,同时探讨品种配套栽培技术。[结果]试验结果表明,CF9087、CF3807抗病性较好、经济效益达到40000元/hm2,比对照NC89分别提高21.78%、20.50%,上等烟比例较高。最终确定CF9087、CF3807、NC55、K326品种作为今后日照烟区的推广应用品种。施氮量在90kg/hm2时,各品种烤烟产值效益较高。[结论]烤烟新品种CF9087、CF3807、NC55、K326适合在日照烟区推广应用,施氮量以90kg/hm2为佳。
[Objective] To adapt to the actual tobacco production in Rizhao City, to meet the industrial needs and improve market competitiveness. [Method] In Yixian City, Pixian County, a comparative study of new varieties of flue-cured tobacco and comparative experiments in large areas, screening of new flue-cured tobacco varieties, and explore varieties of cultivation techniques. [Result] The results showed that the disease resistance of CF9087 and CF3807 was good and the economic benefit reached 40,000 yuan / hm2, which was 21.78% and 20.50% higher than that of control NC89 respectively. CF9087, CF3807, NC55, K326 will be finalized as the popularization and application of tobacco varieties in the future. Nitrogen rate of 90kg / hm2, the higher the yield of various varieties of tobacco. [Conclusion] The new tobacco varieties CF9087, CF3807, NC55 and K326 were suitable for popularization and application in the tobacco area of Rizhao. The nitrogen application rate was 90kg / hm2.
