应用^(36)Cl研究烤烟施氯效果

Effect of Applying Choline on Flue cured Tobacco Plant with 36 Cl

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 effects of different amount of applying 36 Cl on the flue cured tobacco plant were studied. The results indicated that, with the increase of the amount of applying Cl, the amount of Cl absorbed from the applying fertilizer by the flue cured tobacco plant increased, and the Cl amount from the soil decreased. At the same time, the amount of total K 2O absorbed and the dry matter mass of the flue cured tobacco plant also increased , but the high amount ( 5g ) if applying Cl decreased the amount of total absorbed K 2O and the dry matter mass. Effects of applying Cl on the flue cured tobacco plant in different soils showed that, in the soil with higher amount of Cl, the amount of Cl absorbed from fertilizer and the soil, the amount of total K 2O absorbed and the dry matter mass of the flue cured tobacco plant were all higher than those in the soil with lower amount of Cl.
