摘要：

为探索津引品种‘KRK26’在云南省昭通市的栽培技术，研究种植密度和留叶数对其主要经济性状的影响。结果表明：以株行距为120 cm×55 cm、留叶数为21片的处理的产量、产值和产指最高；以株行距为120 cm×55 cm、留叶数为23片的处理的均价、级指和上等烟比例最高。在昭通市种植津引品种‘KRK26’以采用行距120 cm、株距55 cm、留叶数21~23片的栽培措施较适宜。

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.
