文山烟区生态条件及烟叶质量评价

Evaluation of ecological factors and flue-cured tobacco quality in tobacco-growing area in Wenshan

为了进一步发挥文山得天独厚的生态条件,不断生产出优质烟叶原料,对云南文山烟区气候因素、土壤养分状况及所产烟叶的质量特点进行了分析,结果表明:文山烟区积温高,气温适宜,日照充足,降雨充沛;植烟土壤p H值适宜,有机质含量丰富,具有较强的保肥能力;氮、磷、钾含量适宜,多数中微量元素含量适宜;有效硼含量偏低,有效硫含量偏高,应注意追施硼肥,控制硫肥;文山烟叶外观质量及感官质量较好,化学组成比例协调,符合优质烟叶标准。

To exert advantages of ecological conditions for producing high quality materials, meteorological factors, soil nutrients and quality of flue-cured tobacco leaves are analyzed in Wenshan, Yunnan Province. The results indicate that Wenshan tobacco growing areas had high accumulated temperature, suitable average temperature, ample sunlight and sufficient precipitation. The soil condition has feasible p H value, strong capability of storing nutrients and is rich in organic matter. The contents of N, P, K and most medium-micro elements are suitable. The content of available B is low, but available S is high and it is suggested to add B and reduce S for balanced fertilization. Wenshan tobacco leaves have high quality of appearance, sensory and reasonable constitution of chemical components, which correspond with the standard of high quality flue-cured tobacco.
