摘要: 【目的】在武陵山区引进和推广横坡起垄栽培技术,需要提出适宜坡地烤烟种植、能提升烟叶产质量的改良方案。【方法】选择常见坡度(15°)烟地,以云烟87为参试品种,按随机区组试验设计,开展顺坡起垄、横坡起垄、75°倾斜横坡起垄、60°倾斜横坡起垄四个处理三次重复田间试验,分析不同处理条件下烟田垄体土壤含水率动态变化、烟株农艺性状、经济性状和烟叶化学品质等性状。【结果】结果表明75°倾斜横坡起垄与横坡起垄能促进上部叶开片,增加上部叶叶宽;75°倾斜横坡起垄产量最高,且与60°倾斜起垄间存在显著差异;75°倾斜横坡起垄产值显著优于横坡起垄、顺坡起垄和60°倾斜横坡起垄,上中等烟率显著高于60°横坡起垄;烟叶化学成分协调性在四个处理间差异不明显。【结论】综合分析,常见坡度烟田进行起垄种植时,75°倾斜度起垄有助于垄体保水调肥,达到增产增值的目的。

Abstract: To introduce and promote the cultivation technique of ridge on horizontal slope in Wuling mountainous area, it is necessary to put forward an optimized cultivation technique, which will be suitable for planting flue-cured tobacco on hillside and improve its quality and quantity. In this study,‘Yunyan 87’was planted on the 15° angle hillside field treated by four cultivation techniques of slope ridging, cross ridging, askew ridging (slanted 75°) and askew ridging (slanted 60°) with three duplications via randomized block design. And the dynamic changes of soil moisture in the ridges, agronomic traits, economic traits and leaf chemical components of tobacco under different treatments were analyzed. The results showed that the cross ridging and askew ridging (slanted 75°) promoted the opening of the upper leaves and increased the width of the upper leaves in tobacco. The yield of tobacco planted in the askew ridge (slanted 75°) was the highest, and significantly higher than that in the askew ridge (slanted 60°). The quality of tobacco planted in the askew ridge (slanted 75°) was significantly better than that of other ridges. And the proportion of upper and medium leaves of tobacco planted in the askew ridge (slanted 75° ) was significantly higher than that of the askew ridge (slanted 60° ). However, the coordination of inherent chemical composition of tobacco leaves in the four treatments was not significantly different. In conclusion, ridges with a gradient of 75° could help the ridge to retain moisture and fertilizer, and achieve the purpose of increasing production value when planting tobacco in the common hillside field.
