Abstract:

The effects of plant density and the remained leaves number on main economic characters of ‘KRK26’ of Zimbabwe introduced flue-cured tobacco cultivar in Zhaotong city of Yunnan Province were studied to explore the its cultivation techniques. The results showed that: the plant-row-line-spacing combining of 120 cm×55 cm and the 21 remained leaves number had the best yield, value and output index. The plant-row-line-spacing combining of 120 cm×55 cm and the 23 remained leaves number had the best average price, grade index and proportion of high grade leaves. The appropriate cultivation measures of the ‘KRK26’, Zimbabwe introduced flue-cured tobacco cultivar were 120 cm row spacing, 55 cm plant spacing and 21 to 23 remained leaves number in Zhaotong city of Yunnan Province.
