| 摘 要： | 通过对河南省烟区 135 3个灌溉水样分析表明 ,全省烟区灌溉水全盐量平均为 380 .1m g/ L,氯含量平均为31.98mg/ L。五大植烟区比较 ,全盐含量顺序为 :豫东 >豫中 >豫西 >豫南 >豫西南 ;氯含量顺序为 :豫东 >豫中 >豫南 >豫西南 >豫西。全省约有 80 %烟田灌溉水氯含量比较适宜。 |
| 关 键 词： | 烟区 灌溉水 氯 全盐量 |

| Abstract: | The present situation of salinity and chlorine contents in irrigation water in tobacco-growing areas in Henan Province were analyzed by 1353 water samples taken from tobacco-growing areas. Results showed that average salinity and chlorine content was 380.1 mg/L and 31.98 mg/L respectively. The order of irrigation water salinity from high to low in tobacco-growing areas in Henan is about: east area, middle area, west area and south area. For chlorine content of irrigation water, the order is about: east area, middle area, south area, southwest area and west area. The chlorine contents in about 80% of tobacco growing areas in Henan are suitable for tobacco cultivation. |
| Keywords: | tobacco growing area irrigation water chlorine salinity |
