采用调整移栽期的方法,对四川达州白肋烟区各生育期气候指标进行研究。结果表明,推迟移栽期可以减少伸根期和成熟期的天数,增加旺长期的天数。气温受移栽期的影响最大,其次为土壤湿度、空气湿度、平均日照和日照时数。移栽期对降雨量的影响具有偶然性。随着移栽期的推迟,气温类指标(日均温、活动积温、有效积温、日照时数)都表现为在旺长期逐渐升高,在成熟期先增高再降低。其中均温和有效积温在整个生育期表现为随着移栽期的推迟逐渐升高。而积温、日照时数、土壤湿度在伸根期表现为先降低后升高。

Climatic indices of growth stages of burley tobacco in Dazhou were investigated by adjusting transplanting dates. The results showed that delaying transplanting dates could reduce the time of root elongation and maturity, increase the days of vigorous growth stage. The change in transplanting time had the greatest impact on air temperature, followed by soil moisture, humidity, sunshine and the average number of sunshine hours. The effect of transplanting dates on precipitation was not consistent. The air temperature indices, including daily average temperature, accumulated temperature, effective temperature, and sunshine hours, all increased gradually in the vigorous growth stage, and increased first and then decreased in maturity stage with postponement of transplanting dates. Average temperature and effective temperature gradually increased with postponement of transplanting dates in the whole growth period. Accumulated temperature, sunshine hours and soil moisture decreased first and then increased in root elongation growth stage.
