| 摘要: |
| 烤烟酸化水灌溉试验和微肥施用试验表明，酸化水灌溉能降低土壤pH值，使之接近于烤烟适宜生长范围；同时土壤速效磷、速效钾含量增加，硼、锰的有效性得到改善；烟叶的外观品质和含钾量也有所提高。施用微肥增加了旺长期烟叶的叶绿素含量和NR酶的活性，烤烟生长得到促进，产量和品质提高。 |

| Effects of Acid Water and Trace Element Fertilizer on Fluecured Tobacco |
|
|
| Abstract: |
| The pot experiments of the effects of acid water irrigation and trace element fertilizer application show that the irrigation with acid water can decrease the soil
pH value, increase the contents of available P and K in soil, improve the efficiency of B
and Mn, and improve the quality and K content of tobacco leaves.Also, the application of
trace element fertilizer can increase the content of Chlorophy ll and the activities of NR
enzyme of tobacco leaves,Thus improves the growth, yield and quality of tobaccos. |
| Key words: acidwater, trace elelment fertilizer, tobacco quality |
