土壤调理剂对烤烟产质量的影响

Soil Conditioner: Effect on Yield and Quality of Flue-cured Tobacco

【目的】改善植烟土壤结构、提高植烟土壤质量,提高烟叶产质量。【方法】以云烟87为材料,研究不同用量的土壤调理剂对烤烟农艺性状、产质量及土壤养分含量的影响,探索土壤调理剂在提高烟叶产质量上的效应。【结果】施用土壤调理剂对烟叶农艺性状及气体交换参数有一定影响,显著提高烟叶的产量,施用土壤调理剂375kg/hm^2、1500kg/hm^2的烟叶增产幅度分别为9.85%、19.38%;显著提高烟叶含钾量和土壤中碱解氮、有效磷、速效钾含量。施用土壤调理剂处理对烟叶中上等烟比例无显著影响,提高了烟叶水溶性总糖含量,而烟叶的化学成分的协调性却有所降低。【结论】综合分析表明,施用适量土壤调理剂利于烤烟产量的提高及植烟土壤环境的改善。

[ Objective ] It aims to improve the structure ＆ quality of tobacco-planting soil and therefore improve yield and quality of tobacco. [ Method ] With Yunyan 87 as material, research is conducted to explore effects of different amounts of soil conditioner on soil nutrient content and agronomic traits, yield ＆ quality of flue-cured tobacco. [ Result ] Applying soil conditioner has certain effects on agronomic traits and gas exchange parameters of tobacco, significantly increasing the yield ＆ potassium content of tobacco, and the content of available nitrogen, phosphorous ＆ potassium in soil. The yield is 19.38% respectively by applying soil conditioner of 375kg/hm2 and 1500kg/hm raised by 9.85% and 2. There is no obvious effect on proportion of superior-middle tobacco with soil conditioner： the total content of water soluble sugar increases, while the coordination of chemical component decreases. [ Conclusion ] It can be concluded from the above that applying appropriate amount of soil conditioner can help improve yield ＆ quality of flue- cured tobacco and environment of tobacco-planting soil.
