| 摘 要： | 在湖南永州、衡南烤烟区进行的田间试验结果表明,适量的氯素营养有利于提高烤烟旺长期叶片中的叶绿素含量和植株根系活力,提高烤烟生长前期硝酸还原酶(NRase)的活性;在氯含量较低的土壤上,烟草所施用的钾肥中,氯化钾所占比例为15%～30%时(以K2O计),烟叶增产5.2%～16.9%,产值增加1911.0～7348.5元/hm2,中上等烟比例提高10.2～11.5个百分点,同时还能改善烟叶的品质.在我省及南方一些土壤氯含量较低的地区,在烟草上可考虑适当施用一定量的氯化钾部分代替硫酸钾,以降低肥料投入,提高经济效益. |

| Abstract: | Field experiments were carried out in main tobacco production area in Hunan province. Results showed that proper application of Cl can increase chlorophyll content in tobacco leaf and root activity at vigorous growing stage, enhance NRase activity in tobacco leaves at prophase of growth. KCl application at 15%~30%(K 2O) total amount of potassium fertilizer increase flue-cured tobacco yield by 5.2%~16.9%,output value by 1911.0~7348.5 RMB/hm2, proportion of middle and superior tobacco leaves by 10.2%~11.5%, improve flue-cured tobacco quality on low-chlorine content soils. In order to reduce cost of fertilizer and increase economic benefit, KCl should be partly used instead of K 2SO 4 on low-chlorine content soils in Hunan and south China. |
