| 摘 要： | 系统分析四川晒黄烟区农业气候要素年变化规律和特征对优质烟叶生产具有一定理论指导意义。笔者系统分析了四川省什邡市近30年温度、日照时数和降雨量等主要气候因子变化趋势，研究了当地烟草生育时期和烟叶调制时期主要气候因子对烟草生长和烟叶调制的影响。结果表明，四川什邡晒黄烟区近30年温度逐年升高，降雨量逐年增加；日照时数变异幅度较大；从总体来看，温度、降雨量以及日照时数等主要气候因子可以满足优质烟叶生产要求，但是在烟草生育时期明显存在温度过低和降雨偏少的问题，在烟叶调制时期又存在日照时数太少和降雨量过多的问题。因此，根据该地区气候要素变化规律和特征，适当调整栽培措施，可使烟草各生育时期处于更有利的气候条件下，提高优质烟叶生产水平。

Studies on Climatic Changes Characteristics for Sun-cured Tobacco Area in Shifang over Past 30 Years |

| Abstract: | Climatic factors such as temperature, precipitation and so on play an important role in the distribution of tobacco and have an important effect on the yield and quality of tobacco. Based on historical climatic data over past 30 years in Shifang city, the principles of climatic changing characteristics for sun-cured tobacco area were observed. The results showed, the average annual temperature and precipitation increased obviously during the past 30 years. For the sunshine hours during the past 30 years, there was no obviously trend to increase or decrease. In sum, the climatic conditions of Shifang area were relatively suitable for producing sun-cured tobacco, however, it was not suitable for the production of tobacco leaf to be the lower temperature and the less rainfall in the growth period and the less sun-shine hours and the more rainfall in the harvest period. Therefore, these results could facilitate our understanding of the principle and characteristics of climatic factors in sun-cured tobacco area and provide some helps of production of good tobacco leaf. |
