摘要
研究了低氯磷钾复肥对香料烟和晒红烟的产量和品质的影响．结果表明，在土壤氯含量较低（＜１００μｇ／ｇ土）或有足够的降水能够把氯淋出根层的地区，低氯磷钾复肥配合无氯氮肥可以代替氮磷钾（钾来自Ｋ２ＳＯ４）三元复肥施于烟草．低氯磷钾复肥能够提高两者的产量和品质，烟叶中氯的含量可低于２％（晒红烟）或１％（香料烟）．
The effect of a phosphate rocksulfuric acidpotassium chloridecomplex fertilizer with a low chloride content (PKLCl) on the yield and quality of aromatic and suncured tobacco was studied. In areas where the soil is deficient in Cl and /or the rainfall is sufficient to leach the chloride below the plants' root zone, application of PKLCl, together with a N fertilizer,substituting for NPK complex fertilizer (K from K2SO4), can be administered to the tobacco. The PKLCl was able to increase the yield and improve the quality of curedleaf tobacco, while the Cl content in the curedleaf was still below 2% and 1% for suncured tobacco and aromatic tobacco respectively.
