摘 要:通过对舞阳县近5年的生态数据的分析表明:4~6月份的降雨量减少,月平均气温呈现逐渐降低的趋势,这一时期正是烟株旺长的关键时期,因此影响烟叶的早期发育。7~9月份的气温变化幅度较大,气温稳定性差;日照时数在年份间变化没有规律;5年中的空气湿度变化不大;针对气象因子的变化要加强烟田的水分管理,采取各种措施提高烟田水分及地温。土壤分析表明,土壤养分的变化也比较明显,有机质含量从15.0 g/kg(2007年)下降到12.6 g/kg(2010年),从而影响土壤的基本肥力水平;速效氮含量从2007年开始也大幅度下降,近两年维持相当水平;速效磷含量变化不大;速效钾含量呈现增加趋势。因此植烟土壤肥力的恢复,要重视以增施有机肥为主,其他微量元素为补充的烟田土壤修复工作,提高烟田的综合供肥能力,提高浓香型烟叶质量。The analysis of the past five years ecological data in Wuyang showed that: during Apr.-Jun.rainfall is reduced;the monthly average temperature decreased,this period is the critical period for tobacco plant,thus affected the early development of the tobacco.The amplitude of temperature change during Jul.-Sep.is large;the inter-annual variation of sunshine hours has no law.Little change in air humidity in the past five years;strengthen the tobacco fields of water management according to the changes of the meteorological factors and take various measures to improve the tobacco fields of water and ground temperature.The analysis of soil showed that: the changes of soil nutrient are more obvious,organic matter content decreased from 1.5%(2007) to 1.26%(2010),thus affected the soil fertility level,available nitrogen has declined dramatically since 2007,the last two years it kept a considerable level.Available phosphorus content had little change.The potassium content increased.Soil nutrients spatial recovered from paid mainly organic manure and other trace elements that improved the tobacco fields of fertility to increased the quality of Luzhou-flavor tobacco.
