| 摘 要： | 通过盆栽试验研究了烤烟单施化肥，化肥＋芝麻饼肥和化肥＋腐植酸对植生过程中土壤营养状况的影响。结果表明：各处理烟草在生长后期根区土壤ＰＨ值普遍下降，处理Ⅱ和处理Ⅲ能够加强这种下降趋势，烤烟对Ｎ肥的大量吸收 在移栽后４０－６０ｄ，由于饼肥的缓效性。 |

| Abstract: | Pot experiment was conducted to study the effects of applying different types of fertilizers on soil nutrition during development of flue cured tobacco.The results showed:the soil pH was declining during the later stage of tabacco development,and the humic acid or cake fertilizer could enhance the tendency;soil nitrongen was absorbed concentrating on the 40 60 days after transplanting.The treatment of cake fertilizer chemical fertilizer would make soil nitrogen insufficient during the early stage of tobacco that is unfavorable to the growth after transplanting,while the treatment of humic acid chemical fertilizer had not only the rapid action as well as the durability of manure.This supplied tobacco with an equilibrium and proper nutrition;soil phosphorus was absorbed concentrating on the rapid growth period,while the treatment of humic acid chemical fertilizer could last to the round top period;each treatment had no obvious effects on soil potassium. |
