１９９２～１９９３年期间，对种植于红壤、紫色土和黄壤上的烤烟开展了不同施氯量（０、３１．５、６３．０、９４．５、１２６．０、１５７．５ｋｇ／ｈｍ２）与烟叶含氯量相互关系的田间试验研究，以及施氯后土壤氯的动态观测与室内氯的土柱淋溶模拟实验。结果表明，在ｍ／（Ｎ）、ｍ（Ｐ２Ｏ５）、ｍ（Ｋ２Ｏ）用量为１１２．５ｋｇ／ｈｍ２。１１２．５ｋｇ／ｈｍ２：２８１．２５ｋｇ／ｈｍ２的基础上，烟叶含氯量随施氯量的增大而增加，彼此呈显著的指数函数关系。每公顷施氯９０ｋｇ左右对四川烤烟生产是安全而适宜的，烟叶含氯量约为０．６％，对烟叶产、质无不良影响，且可增强香气量、改善香气质，氯也不致于在土壤中明显累积。氯的淋溶模拟实验显示，只要保持连续下渗水流６至７天，所施加的氯量（９０．０ｋｇ／ｈｍ２）便可淋溶殆尽。
During 1992-1993, different amount of chlorine application (0,31.5,63.0,94.5,126.0,157.5kg / hm2) and different amount of chlorine were applied to flue-cured tobacco planted on red soil, purple soil and yellow soil, Field experiments on the relationship between chlorine content in tobacco leaf and the dynamic observation of soil chlorine after soil chlorine application and soil column leaching simulation experiment of indoor chlorine. The results showed that with the dosage of m / (N), m (P2O5) and m (K2O) 112.5kg / hm2.112.5kg / hm2: 281.25kg / hm2, Increase with the increase of each other was a significant exponential function. About 90kg of chlorine per hectare is safe and suitable for the production of flue-cured tobacco in Sichuan Province. The content of chlorine in tobacco leaves is about 0.6%, which has no adverse effect on yield and quality of tobacco leaves, and can enhance the aroma quantity and improve the fragrance quality. Significantly accumulated in the soil. Chlorine leaching simulation experiments show that the amount of chlorine applied (90.0 kg / hm2) can be leached as long as the continuous seepage flow is maintained for 6 to 7 days.
