设置了3种烤烟栽培模式,研究其对兴义市特色优质烟叶的影响。结果表明:采用当地栽培措施栽培其产值和产量能达到较高水平,但烟株株型特征及部位结构不够合理,生育期较长,烟叶落黄不够好,加大了烘烤难度;而采用扩行缩株、高密度低施肥水平等技术措施栽培的烟叶株型及等级结构合理,烟叶落黄良好,烤后烟叶上中等比例高,产值、产量也能达到一定水平,且烤后烟叶物理外观性状良好,内在化学成分协调;缩行扩株技术栽培效果则不佳。
Three kinds of flue-cured tobacco cultivation patterns were set up to study their effects on the quality and quality of tobacco in Xingyi. The results showed that the cultivation and cultivation of its output value and yield could reach a higher level. However, the plant type and site structure of the tobacco plant were not reasonable enough, the growth period was longer, the yellowing of the tobacco leaf was not good enough, which increased the difficulty of baking. Expansion and contraction lines, high-density and low fertilization levels and other technical measures to cultivate tobacco plant type and grade structure is reasonable, good off-yellow tobacco leaf after roasting, the middle proportion of high yield and output can reach a certain level, and roasted tobacco leaf physics The appearance of good characters, internal chemical composition of coordination; expansion of the expansion of technology is not good.
