摘要：

为探明主要气象因子对山地烤烟生长发育进程的限制与影响，优化烤烟生育期，做好烟草青枯病的预测预报和合理防控，通过连续2年的烤烟主栽品种‘云烟87’、‘K326’、‘HN2146’的不同移栽期大田试验，探索生育期变化规律，研究日照及温度与烤烟生育期、青枯病的关系。结果表明：（1）烤烟团棵期和旺长期随移栽期延迟而显著减少，其原因是温度随移栽期推迟而显著升高，使生育进程加快；累积日照时数的减少有随生育时间缩短而变化的趋势。（2）温度、日照对烤烟的主要效应时期在团棵期与旺长期，主要影响在现蕾以前，其中温度是影响湘西烤烟生育期的关键因子。（3）平均日照时数与平均气温是影响生育期的主要因子，其中关键主要因子是平均气温。（4）青枯病重点防治期为烟叶移栽63 d之前且均温未达21.82℃之前，重点预防期为均温未达18.77℃之前且烟叶移栽42 d之前。温度对于指导青枯病的预测预报和防治具有重要意义。

Abstract:

The study aims to verify major meteorological factors which affect the growth and development process of flue-cured tobacco in mountainous region, properly arrange field growth period, and better forecast and prevent tobacco bacterial wilt. We conducted field experiments for two consecutive years by using three main tobacco varieties of ‘Yunyan87’, ‘K326’ and ‘HN2146’ with different transplanting dates, to analyze the change rule of tobacco growth period, and define the relationship between the temperature and sunshine and the bacterial wilt and growth period of flue-cured tobacco. The results are as follows. (1) The growth period of tobacco was significantly shortened with the delay of transplanting date, mainly in the vegetative growth stage (root extension period) and reproductive growth stage (exuberant growth period) before budding. The temperature of early growth stage increased significantly with the delay of transplanting date, speeding up the development process. The accumulated sunshine hours decreased due to the shortened growth period. (2) The effect of temperature and sunshine on the growth period of flue-cured tobacco was mainly found before budding, and their primary function mainly took place during the vegetative growth stage and reproductive growth stage. Temperature was the key meteorological factor affecting the growth period of tobacco in Xiangxi. (3) The average temperature and average sunshine hours were the main meteorological factors during tobacco growth period, and the average temperature was the key meteorological factor. (4) The key control period of bacterial wilt was 63 days before tobacco transplanting and before the average temperature reached 21.82℃; and the key prevention period was before the average temperature reached 18.77℃ and 42 days before tobacco transplanting. Therefore, temperature was important in forecasting and prevention of tobacco bacterial wilt.
