| 摘 要： | 目的]为烤烟生产和满足工业需要提供理论和技术依据。方法]试验于2007年在恩施州宣恩县椒园镇凉风村进行,云烟87为供试品种,在当地土壤肥力的基础上,设计4个不同的施肥处理,测定不同处理烟的农艺性状、经济性状和常规化学成分,探索不同氮素形态和不同施肥时期对烤烟生长发育和品质的影响。结果]有效叶片数和单株叶面积4个处理间无明显差异,其他指标L3(提前30 d施基肥的处理)明显优于CK(全施无机肥的处理),最大叶宽、根系干重、单位面积产量、单位面积产值和中上等烟比例L3分别比CK高24.87%3、8.50%、28.74%5、8.80%和28.38%。结论]有机态氮与无机态氮配合施用,且有机态氮做基肥提前30 d左右施入能够促进烤烟生长发育,提高其产量和品质。 |

| Abstract: | Objective] The study was to provide the theoretical and technical basis for the production and industrial needs of flue-cured tobacco.Method] The test was carried out in Liangfeng village,Jiaoyuan Town,Xuanen County of Enshi Autonomous Prefecture in 2007 with Yunyan 87 as the test cultivars and 4 different fertilizer treatments were designed on the basis of local soil fertility condition.The agronomic characters,economic characters and normal chemical components of flue-cured tobacco with different treatments were detected,and the effects of different nitrogen forms and fertilization time on the growth and development and quality of flue-cured tobacco were explored.Result] The number of effective leaves and leaf area per plant had no obvious differences among the 4 treatments,other indexes of L3(the treatments of base fertilizer being applied ahead of 30 d) significantly surpassed that of CK(the treatment being applied inorganic fertilizer only),the largest leaf width,dry weight of roots,yields of unit area,output value and the ratio of middle and superior tobacco of L3 was 24.87%,38.50%,28.74%,58.80% and 28.38% higher than that of CK resp.Conclusion] The combining application of organic nitrogen and inorganic nitrogen,and the organic nitrogen being all applied ahead of about 30 d as base fertilizer could promote the growth and development of tobacco,and increase its yield and quality. |
