施用沸石对烤烟生长效应的研究

Study on Effects of Zeolite Application on Growth of Flue-cured Tobacco

盆栽试验结果表明：每千克风干土中施入2-3g沸石能明显促进烤烟植株生长，使烟株比对照增高8．6％-9．8％；茎围增粗3．9％-5．8％；烟叶干重提高5．4％-6，9％；烟叶中钾含量提高0.81—1．83个百分点，氯含量降低0.07-0.12个百分点。

The results of pot culture test showed that applying zeolite to dry soil at the dosage of 2-3g/kg could obviously promote the growth of tobacco plant, and increase the plant height by 8.6% -9.8%, accelerate the stem width by 3.9% -5.8%, increase the dry tobacco leaf weight by 5.4%- 6.9% and the content of kalium in tobacco leaf by 0.81- 1.83 percent, and decrease the content of chlorine by 0.07-0. 12 percent.
