为明确山地植烟土壤粉垄耕作的效果和适宜深度,设计粉垄深度30 cm、40 cm、50 cm和传统耕作4个处理,分析了粉垄耕作后烤烟根系和地上部分生长动态变化,研究了粉垄对烤烟干物质、氮、磷、钾、烟碱、氯的积累分配,以及对烤烟经济性状和烟叶化学成分的影响。结果表明,粉垄可促进烤烟根系和地上部生长,粉垄深度增加有利于根系下扎。粉垄有利于烤烟干物质、氮、磷、钾、烟碱、氯的积累;烤烟物质积累主要分配给烟叶,粉垄深度40~50 cm有利于干物质、氮、磷、钾向根系分配,粉垄深度50 cm有利于烟碱、氯向根系分配。适当深度的粉垄有利于提高烟叶产量和产值。粉垄可提高烟叶钾含量,但是也提高了烟叶的烟碱...

To determine the effect and appropriate depth of smashing ridge tillage in tobacco-planting soil,4 treatments including 30 cm,40 cm,50 cm depth of smashing ridge tillage and traditional cultivation were designed to analyze the dynamic changes of roots and above ground growth of flue-cured tobacco,and to study the effects of smashing ridge tillage on accumulation and distribution of dry matter,nitrogen,phosphorus,potassium,nicotine and chlorine of flue-cured tobacco,as well as economic properties and chemical composition of flue-cured tobacco.The growth of tobacco roots and aboveground parts co...
