摘    要:盆栽试验表明,烟叶含Cl量与施Cl量呈极显著线性正相关,但随生长时期而降低,至成熟期低于0.4%。在肥料含Cl0%~12%时,烟叶产量随施Cl量增加而增加,以施含Cl 12%的肥料最高,比对照增产41.3%。但含Cl 15%时,则有毒害作用,产量明显降低。施Cl 3%~9%有助于提高烟叶含K量和调节K_2O/Cl比,而对烟株N,P营养无明显影响。提高烟叶品质和产量的适宜肥料含Cl量为6%~9%(即施Cl 74~107mg/kg±)。

关 键 词:  肥料  烤烟  叶片  含氯量

Abstract:In a pot experiment, a highly significant positive linear correlation was found between Cl concentration in tobacco leaves and the percentage of Cl in the fertilizer. Cl in tobacco leaves drcreased with gowth period and dropped to less than 0. 4% when the crop matured. The yield of tobacco leaf increased with Cl percentage in it in the range of 0-12%. In the treatment of 12% Cl, the yield of tobacco was raised by 41. 3% over that in the control. However, a percentage of 15% of Cl appeared to be toxicogenic to the plants and reduced the yiled. Cl concentration in the range of 3 - 9 % was helpful for increasing K content in the leaf and adjusting K2O/Cl ratio without negative influence in N,P nutrition of the tobacco plants. From the results of this experiment, a proportion of 6 - 9% of Cl in the fertilizer, or 72-107 mg Cl/kg soil, is recommended for tobacco cultivation.
