气候条件对烟草生长的影响分析

Effect of Climate Conditions on Tobacco Growth

为指导烟草技术人员和烟农根据天气预报有针对性的做好烟草种植管理,利用丹东地区宽甸、凤城2个烟草种植区观测站1955—2010年逐年逐日气温、日照、降水量等资料,综合运用天气学及线性统计方法,选取烟草歉收年、丰收年的气象资料对烟草生长过程的影响进行分析。结果表明:1气温、光照、降水(除主汛期降水外)在历年均值附近都是丹东烟草生长的适宜时段。2当光照低于历年均值,说明阴雨时间长光照不足,影响旺长期或成熟期烟草生长,导致产量下降。3当大田生长期温度、光照超过历年均值越多,成熟期降水量比均值少两成以下,就越有利于烟草增收。

In order to guide the tobacco technicians to make better tobacco management according to the weather forecast,using daily temperature,sunshine and precipitation data of 2observation stations from 1955 to 2010year of Kuandian,Fengcheng tobacco planting area in Dandong,the integrated use of synoptic and linear statistical method,selecting the meteorological data of the lean years and bumper year of tobacco,the influence of meteorological data in harvest years on growth of tobacco was analyzed.The results showed that1 Temperature,precipitation,illumination（in addition to the main flood season precipitation outside）in the vicinity of average is suitable for Dandong tobacco growth.2 When the light was lower than the average,that rainy time long photoperiod shortage,affect tobacco growth during vigorous growing stage or mature period,lead to a decline in yield.3When temperature and light of the field growth period more than an average,precipitation less than 20% of average,helpe to increase tobacco yield.
