应用36Cl研究烤烟不同施氯量的结果表明:随着施氯量的增加,烤烟吸收肥料中氯量增多,而吸收土壤中氯量减少;随着施氯量的增加,烤烟吸收总K2O量和烤烟干物质量增加,但施高氯量(施5g氯)使烤烟吸收总K2O量和干物质量反而下降。不同土壤烤烟施氯效果表明:含氯量高的土壤,烤烟吸收肥料和土壤中氯量多,吸收总K2O量和烤烟干物质量也增加;含氯量低的土壤烤烟吸收肥料和土壤中氯量少,吸收总K2O和干物质量下降。
The results of applying 36Cl to study the different amount of chlorine application in flue-cured tobacco showed that the amount of chlorine in flue-cured tobacco increased with the increase of chlorine application amount, while the amount of chlorine in the absorbed soil decreased. With the increase of chlorine application amount, The quality of flue-cured tobacco increased, but the application of high-chloride (5g chlorine) decreased the total amount of K2O and dry matter absorbed by flue-cured tobacco. The effect of chlorine application in different soil flue-cured tobacco showed that the soil with high chlorine content had higher amount of chlorine, more total K2O, and more dry matter in flue-cured tobacco; the content of chlorine in soil and flue-cured tobacco Less, total K2O uptake and dry matter weight decreased.
