不同雪茄烟品系农艺性状与干物质积累研究
The Study of Agronomic Characters and Dry Matter Accumulation of Different Cigar Strains
摘要
Abstract
This study aims to select cigar tobacco cultivars suitable for cultivation in the Shandong tobacco-growing region and explore the growth and quality characteristics of cigar tobacco in the Shandong region.Five domestic high-quality cigar tobacco cultivars(QX100,QX102,QX103,QX105 and QX107)were selected as experimental materials and subjected to field experiments at different locations.Following the methods outlined in YC/T142‒2010 Methods for Investigation of Agronomic Traits of Tobacco,differences in field traits,nutrient absorption and accumulation,and quality characteristics among different cigar tobacco cultivars were studied using continuous flow analyzers and flame photometers.The results showed that in terms of growth period,the differences in the growth period among the various cultivars of cigar tobacco in Linqu are relatively small,while QX102 and QX105 in Yishui show significant differences.QX102 has a longer time from budding to central flower opening,whereas QX105 experiences a shorter duration.There are no significant differences in botanical traits between the two locations.Regarding agronomic traits,in Linqu,QX100 exhibits the tallest plant height,wide and thin leaves,and few and slender veins;QX102 has the highest leaf number but smaller leaves and the most veins;QX103 has shorter plant height and longer leaves and with thicker leaf blades;QX105 has the smallest leaf width and thinner veins;QX107 has larger leaves with the thickest veins.In the Yishui experimental site,QX100 shows the tallest plant height,longest internode distance,longest leaf length,and widest leaf width,with significant differences from other cultivars except in leaf length.Additionally,it has a smaller stem girth,smaller stem-leaf angle,and the thinnest veins.QX102 exhibits shorter plant height,more leaves,and shorter internode distances;QX103 has thicker leaves and veins;QX105 has shorter plant height and smaller leaves;QX107 has larger,thinner leaves.Regarding dry matter and nutrient accumulation,QX103 shows the highest accumulation of leaf and total dry matter,while QX100 has higher phosphorus and potassium content in leaves but weaker nutrient accumulation compared to QX103.QX103 also exhibits the highest accumulation of nitrogen,phosphorus,and potassium,while QX105 has the lowest phosphorus accumulation,and QX107 has the lowest potassium accumulation.After curing,QX100's leaves turn brown with the highest single leaf weight,while QX107 exhibits the thickest original tobacco thickness and relatively heavy single leaf weight.Taking into consideration the overall field performance,accumulation of nutrients and dry matter,as well as quality traits,QX100 and QX103 demonstrate relatively better performance.They are more suitable for the production of cigar wrapper leaves and can be recommended as the main cultivated cigar wrapper cultivars in the Shandong tobacco-growing region.关键词
