摘要
[目的]确定云烟87在利川市海拔1 000～1 200 m区域种植时的最适留叶数.[方法]采用田间小区试验,研究了海拔1 000、1 100和1 200m区域上部烟叶留叶数对云烟87生育期、赤星病发病情况、上三叶和下三叶产值量的影响.[结果]在海拔1 000～1 200m烟区,上部烟叶留叶数在8片时,赤星痛的发病率在5％～9％,减少留叶数能够有效减少赤星病的发生.在海拔1000m和1 100m烟区,与上部烟叶留叶4片和8片相比,留叶6片增加了上三叶和下三叶的产量和产值.而在海拔1200m烟区,上部烟叶不同留叶数对上三叶和下三叶产量的影响表现出不同的变化规律,但是留叶8片处理烤烟上三叶和下三叶的产值均最高.[结论]在利川市海拔1 000～1 100m烟区,种植云烟87适宜的上部烟叶留叶数为6片,而1 200m以上以留叶8片为优.
Abstract
[Objective] To determine the appropriate upper remained leaves of Yunyan 87 on the altitudes of 1 000-1 200 m in Lichuan City.[Method] Field experiment was carried out to study the effects of upper remained leaves on flue-cured tobacco growth periods,disease ocurrence of brown spot,yield and quantity on the altitudes of 1 000,1 100 and 1 200 m.[Result] On the altitude of 1 000-1 200 m,when the upper remained leaves was eight films,the incidence rate of tobacco brown spot was 5％-9％;and reduction of the upper remained leaves effectively reduced the disease.On the altitudes of 1 000 and 1 100 m,compared with 4 and 8 upper remained leaves,6 upper remained leaves treatments increased the yields and values of the topmost three leaves and the bottommost three leaves.On the altitude of 1 200 m,the effects of upper remained leaves on the topmost three leaves and the bottommost three leaves yield presented the different trends,but the highest value of the topmost three leaves and the bottommost three leaves was obtained by 8 upper remained leaves treatments.[Conclusion] The appropriate number of upper remained leaves for Yunyan 87 is 6 on an altitude of 1 000-1 100 m in Lichuan city.However,the appropriates number of upper ramained leaves is 8 on altitude of 1 200 m in Lichuan city.
