摘要
打顶抹杈是烟草工艺非常重要的一步,不仅能提高烟株中营养物质的再分配与利用,提高烟叶的质量,还能抑制烟株的生殖生长,延长营养生长的时间,提升烟叶的品质。本试验通过对比9种烤烟品种打顶前后上部叶中矿质元素和土壤速效钾含量变化的研究发现,不同元素在打顶前后的含量变化各有不同,具体表现在:K+、Cu2+在打顶前后的含量降低,Ca2+和Cl−的含量增加,土壤速效钾的含量增加。对不同营养元素进行测定分析,明确各元素的变化趋势,对后续优质上部烟叶的生产具有重要的参考价值。
Topping and wiping is a very important step in the tobacco process, which not only improves the redistribution and utilisation of nutrients in the tobacco plant and improves the quality of tobacco, but also inhibits the reproductive growth of the tobacco plant, prolongs the time of nutrient growth and improves the quality of tobacco. In this experiment, by comparing the changes of mineral ele-ments and soil quick-acting potassium content in the upper leaves before and after topping of nine roasted tobacco varieties, it was found that the content changes of different elements before and af-ter topping varied, which were as follows: the content of K+ and Cu2+ decreased before and after top-ping, the content of Ca2+ and Cl− increased, and the soil quick-acting potassium content increased. Measurement and analysis of different nutrient elements to clarify the changing trend of each ele-ment has important reference value for the subsequent production of high-quality top-dressing to-bacco.
