摘要
[目的]研究不同封顶时期和留叶数对烤烟产值量的影响.[方法]以云烟87为研究对象,通过大田试验,研究了现蕾封顶和初花封顶,以及留叶16、20、24片对云烟87产值量的影响.[结果]封顶时间相同,大田生育期随着留叶数的增加而增加;留叶数相同,大田生育期随着封顶期的推迟而延长;封顶时间相同,留叶数不同,对烟叶生长有较大影响;各处理对烟株抗病性影响不大.[结论]在该试验条件下,综合产值量效益,云烟87以初花封顶且留叶20片为宜.
Abstract
[Objective] To research the effects of topping time and remained leaves on the yield and the output value of flue-cured tobacco.[Method] With Yunyan 87 as the research object, we researched the effects of topping at bud emergence and early blooming stages and different remained leaves (16, 20, 24) on the yield and the output value based on field experiment.[Result] When the time of topping remained the same, growth period enhanced as the remained leaf number increased.Under the same leaf number, growth period increased as the topping time prolonged.Under the same topping time, remained leaf number had relatively great impacts on the growth of tobacco leaves;the disease resistance of tobacco plants changed slightly in different treatments.[Conclusion] Under the test condition, keeping twenty leaves per plant and topping at the early blooming stage is appropriate for Yunyan 87.
