摘  要：
贵州省烤烟烟叶含氯量一般在0.1%以下,影响烟叶品质,而贵州的年降雨量大都在1200mm左右,烤烟施用KCl后Cl易被淋失。1988—1990年在全省烟区设26个试点,大田生产与盆栽试验相结合,施用KCl以部分代替K_2SO_4肥,目的在于解决部分钾肥来源,改善烟叶品质。研究结果表明,适量施用KCl后,可使烟叶含氯量达到0.4—0.6%的理想范围,对土壤酸碱度及耕作层土壤的含氯量都有明显影响。

摘  要：
The chlorine content in the leaves of flue-cured tobacco (Nicotiana tabacum) is gener- ally bellow 0. 1% in Guizhou Province, and this deteriorate the leaf quality. Guizhou has an average annual rainfall of about 1200mm, so Cl~- of KCl applied to flue-cured tobacco is easily leached away. In order to resolve the problem of shortage of some potash fertilizer sources and improve tobacco quality, 26 experiment plots were set up in different tobacco-grown areas in the province from 1988 to 1990 and both field experiments and pot experiments were carried out to test if KCl could partly replace K_2SO_4 as a potash fertlilizer. The results showed that applying KCl to flue-cured tobacco in an appropriate amount could increase the chlorine content in the leaves up to 0. 4 to 0. 6, which is a desirable range, and had no significant influence on the soil pH and chlorine contents in the arable layers.
