云南生态条件下烤烟KRK26品种成熟采收的研究

Study on Mature Harvesting of Tobacco Variety KRK26 under Ecological Conditions of Yunnan Province

采用叶龄和外观特征两因素对比试验,研究云南生态条件下KRK26品种采收成熟度判断标准。结果显示,现行的云烟系列烟叶成熟采收的判断标准不太适合从津巴布韦引进的多叶型KRK26品种,其成熟度判断应综合考虑叶龄和外观成熟特征,中部和下部叶应参照外观特征以叶龄为主,上二棚和顶部叶应该根据叶龄和外观特征综合判断。

Using the two factors of comparing test by age and appearance characteristics, maturity standards of KRK26 varieties under ecological conditions in Yunnan Province was studied. The results showed that the current tobacco harvest maturity criterion was not suitable for multi-leaf type KRK26 variety introduced from Zimbabwe. Its maturity standards should be synthetically considered the char- acteristics of leaf age and appearance of mature. The tobacco leaves of middle and low position should be mainly based on the leaf age on the basis of appearance and the upper middle and top leaves should be on comprehensive determine between leaf age and appearance characteristics.
