| 中文摘要 | 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。 |
| 英文摘要 | The field trials with different chloride applied levels (0, 31. 5, 63. 0, 94. 5, 126. 0 and 157. 5kg/hm2) had been carried out on red earth,purple soil and yellow earth in 1992-1993. In which the relationship between applied quantn of chloride and chloride contents of tobacco leaves were studied, and the movements of soil chloridet fater applying choride were observed. At the same time an indoor simulating experiment was also conductd for leaching chloride. The results showed: On such basis that 112. 5, 112. 5 and281. 25kg/hm2 of N, P2O5 and K2O were applied respectively, chloride content in tobacco leaf increased with applied quantum of chloride, and there is the regression relation ofexponential function to each other. It is safe and suitable while 90kg/hm’ of chlorid were applied on production of fluf-cured tobacco in Sichuan with approdimately 0. 6% of chloride contents of tobacco leaves, the yield and quality shall not be affected and the quality and quantity of aroma would be enhanced, too. And chlorine would not be accumulated in soil obviously.The simulating experiment of chloride leaching indicated: Ifonly the continuous streams of seeping into soil had been kept about 6～7 days,the increment with applied chloride could be wiped out by leaching. |
