移栽是烟草育苗阶段的结束,大田生产的开始。移栽期的早晚是影响烟草产量和质量的重要因素之一。前人曾对春烟移栽期进行了大量的研究,提出了确定春烟移栽期的气象指标。将其归纳起来有两种提法:一是土壤耕作层的温度稳定在10℃,并有逐渐上升的趋势,才能进行移栽。结合我省烤烟产区一些主要产烟县历年来的气象资料分析,当地面日平均温度稳定在10℃,并有逐渐上升趋势的日期:毫县为4月29日、固镇为4月25日、凤阳为4月29日、宣城为4月9日。可见,我省除皖南烟区外,其余的如毫州、宿州、淮南等烟区是在4月29日,似乎偏迟。二是要在晚霜期过后,即
Transplanting is the end of tobacco seedling stage, the beginning of field production. The sooner or later transplanting period is one of the important factors affecting tobacco yield and quality. Previous studies have done a lot of studies on the transplanting period of spring tobacco and proposed the meteorological index to determine the transplanting period of spring tobacco. To sum up there are two kinds of references: First, soil tillage temperature stabilized at 10 ℃, and there is a gradual upward trend in order to carry out transplanting. Based on the meteorological data of some major tobacco producing counties in the flue-cured tobacco producing areas of our province over the years, when the average daily temperature at the surface stabilized at 10 ° C and the date of gradual upward trend was: April 29 in Muxian and April 25 in Guzhen Day, Fengyang April 29, Xuancheng for April 9. Obviously, except for Southern Anhui Province, our province except the southern part of the tobacco area, the rest, such as the state of Suzhou, Suzhou, Huainan and other tobacco areas on April 29, it seems late. The second is to go after the night frost period, that is
