不同促根肥对烤烟生长发育和品质的影响

摘要

The field plot experiment was carried out in 2011 to study the effect of root - promoting fertilizer on root development, botanical characters, and quality of flue - cured tobacco in Wulong county of Chongqing city. The results showed that the roots and botanical characters in W1 and W4 treatments were better than that in other treatments. The volume, fresh weight, and dry matter weight of root in W1 treatment (105 d) were increased by 20.95% , 99.69% and 22.62% respectively compared with that of CK. The quality of flue - cured tobacco leaves with higher potassium content met the requirements of high quality tobacco when using root - promoting fertilizer. The potassium content in the upper, middle, and down leaves of W5 treatment was increased by 0. 31% , 0.42% and 0.23% respectively as well.%于2011年采用田间小区试验的方式在重庆武隆研究了7个不同配比的窝施促根肥对烤烟根系发育、植物学性状和品质的影响.结果表明:处理W1与W4在根系与植物学性状上的优势较其他处理明显；其中处理W1根系的体积、鲜重、干重(105 d)分别比对照增加了20.95％、99.69％、22.62％；烤后烟叶品质均在优质烟叶要求的范围内,施用促根肥处理烟叶钾含量明显高于对照,处理W5的上部叶、中部叶、下部叶中的钾含量分别比对照高出0.31％、0.42％和0.23％.
