为明确酸性土壤改良剂施用方法,采用三因素二水平的大田试验,研究改良剂种类、施用时间和施用量对植烟土壤pH的影响及对烤烟农艺性状、经济性状和烟叶物理特性、化学成分的效应。结果表明,与对照(CK)相比,施用改良剂能显著提高土壤pH值(移栽后60 d可提高1.24~1.58;移栽后120 d可提高0.39~0.54);施用低剂量石灰有利于打顶前烤烟株高和茎围的生长,施用酸性土壤调理剂有利于打顶前烤烟叶片的生长;施用改良剂主要影响烤烟经济性状指数(ECI) 、烟叶物理特性指数(PPI) 、烟叶总氮含量,以改良剂用量对烤烟经济性状影响最大,改良剂种类和施用时间互作对烟叶物理性状影响最大,改良剂用量对化学成分影响最...

To clarify the application method of acidic soil amendment,a three-factor and two-level field experiment was conducted to study effects of amendment type,application time and application rate on pH of tobacco-planting soil and its effects on the economic properties,physical characteristics and chemical composition of flue-cured tobacco. The results showed as follows:(1) Application of acidic soil amendments significantly increased soil pH(increase soil pH 1.24~1.58 after transplanted 60 d and increase soil pH 0.39~0.54 after transplanted 120 d)...
