皖南烟区不同移栽期气象因子与农艺性状的关系分析

摘要

该文以皖南烟区2015年的气象因子和不同移栽期的农艺性状为依据,分析了气象因子与农艺性状的相互关系.结果表明:(1)气象数据分析显示,3月上旬平均气温偏低,为5.85℃,不适宜烟叶生长,3月下旬为最佳理论移栽时间.(2)3月10日前移栽,团棵期温度偏低,不利于腰叶发育.各移栽期成熟期雨量均较丰富,不利于烟叶成熟落黄.(3)3月19~29日移栽,制约烤烟生长发育的气象因子较少.%Based on the meteorological factors and agronomic traits of different transplanting period of the 2015 in South Anhui Tobacco Area,the article analyzed the relationship between meteorological factors and agronomic traits. The results showed that:(1)Meteorological data analysis showed that the average temperature in early March was low,was 5.85℃,and it was not suitable for the growth of tobacco,and it was the best heoretical transplanting time in late March.(2)Transplanting before March 10th,the group stage temperature is not conducive to the development of middle leaves.The mature period rainfall of each transplanting stage is abundant,is not conducive to the maturity of tobacco middle leaves.(3)Transplanting in March 19th to March 29th,the meteorological factors that restricted the growth and development of flue-cured tobacco were less.
