摘要： 为探讨云南境内不同清香型烟区降雨对烟草种植的影响，以34 年（1971—2004 年）烤烟大田生长期平均降雨量为依据，选降雨量自北向南逐渐增加的昆明市东川区(≤500 mm)、玉溪市江川县(500~700 mm)、玉溪市红塔区(500~700 mm)和普洱市(≥1100 mm) 4 地为模拟降雨量值，在红塔区赵桅烤烟试验基地(24°18′N，102°29′E，1645 m a.s.l.)进行模拟试验，分析了不同烟区降雨量与烟叶δ13C值及生理指标的关系。结果表明：5 个处理烤烟烟叶δ13C值平均值范围为-26.99‰~-25.34‰，表现为T（2 江川）＞T（1 东川）＞T（3 普洱）＞T（4 赵桅）＞CK（赵桅）。各处理间比叶重没有明显差异，而CK叶绿素总量最高，T（4 赵桅）、T（1 东川）、T（2 江川）次之，T（3 普洱）最低。烟叶丙二醛含量T（4 赵桅）最高，T（3 普洱）、T2（江川）、T（1 东川）次之，CK（赵桅）最低。烟叶类黄酮含量T（4 赵桅）最高，T（2 江川）、T（3 普洱）、T（1 东川）次之，CK（赵桅）最低。烟叶可溶性蛋白含量为T（4 赵桅）＞T（3 普洱）＞T（2 江川）＞CK（赵桅）＞T（1 东川）。烟叶δ13C与烟叶可溶性蛋白质、烟叶总碳呈正显著相关；与烟叶类黄酮、碳氮比呈负相关，相关性很弱；与烟叶丙二醛、全氮呈正相关，相关性弱。在降雨量适中的条件下T（2 江川）表现为烟株适生能力较强。

Abstract: In order to investigate the effects of different precipitation of Yunnan tobacco growing areas on field cultivation of tobacco, based on average rainfalls of 34 years (1971-2004) of Yunnan tobacco growing areas, four sites including Dongchuan District of Kunming City (the average rainfalls≤500 mm), Jiangchuan County (500-700 mm), Hongta District (500-700 mm) of Yuxi City and Pu’er County of Nin’er City (≥1100 mm) were chosen because their rainfall were gradually increased from north to south. According to their average rainfalls of 34 years, tobacco‘Yunyan 87’was planted with simulated rainfalls in tunnel house in Zhaowei flue-cured tobacco test base (24°18′N, 102°29′E, 1645 m a.s.l.) of Hongta area. With non-tunnel house planted tobaccos as control(CK), the effects of different simulated precipitation of 4 sites on the tobacco leaf δ13C values and phyto- physiological indicators (PPI) and their correlation were investigated. The results showed that the mean of five treatedδ13C value of tobacco leaves ranged from -26.99‰ to -25.34‰, and the values of leavesδ13C changed as follows: Jiangchuan(T2)＞Dongchuan(T1)＞Puer(T3)＞Zhaowei(T4)＞CK(T5). As for PPI, leaf mass per area-leaf (LMAL), chlorophyll content (Chl), malondialdehyde content (MDA), flavonoid content (FC) and soluble protein content (SPC) were selected to be determined. The LMAL of five treatments have no significant change, however the maximum Chl was found in CK, while that of T4, T1, T2 gradually decreased, and minimum Chl was found in T3; for MDA, T4 was the highest, and the order was T4＞T3＞T2＞ T1＞CK; for FC of tobacco, the order was T4＞T2＞T3＞T1＞CK; and for SPC of tobacco, the order was T4＞T3＞ T2＞CK＞T1. Further statistical analysis showed that tobacco leaf δ13C values had a remarkably positive correlation with SPC and total carbon respectively, and a positive correlation with the MDA and the entire nitrogen respectively with relatively weak relevance, while leafδ13C values had negative correlation with the FC and the ratio of carbon/ nitrogen respectively with very weak relevance. Among all treatment, T2 (Jiangchuan) displayed the strongest adaptability to climate with better growth and development under the moderate rainfall condition.
