氮水平和硝态氮比例对烤烟磷、钾、氯等元素累积分配的影响
Effect of Nitrogen Application Rate and Nitrate Nitrogen Ratio on Accumulation and Distribution of P, K and Cl of Flue-cured Tobacco
摘要
Abstract
[Purpose] The aim of this study was to understand the influence of nitrogen on the absorption of phosphorus (P),potassium (K) and chlorine (Cl).[Method] The effects of nitrogen application rate and nitrate nitrogen ratio on accumulation and distribution of other nutrients of fluecured tobacco were studied.A field experiment was carried out.[Results] The effects of nitrogen application rate and nitrate nitrogen ratio on the contents of P,K and Cl were different.The interaction of nitrogen application rate and nitrate nitrogen ratio had a significant effect on the P content in cutters.The change of the chlorine content in tobacco leaf had no effection the nitrate nitrogen ratio,mainly affected the nitrogen application rate.The influences of nitrogen application rate,nitrate nitrogen ratio and the interaction of them on the K content in tobacco leaves reached significant or extremely significant level.At the same nitrogen application rate and nitrate nitrogen ratio,the allocation rate of P in leaves was higher,but the allocation rate of Cl was higher in stem,lower in root.Applying the same proportion of nitrate nitrogen,with the increase of nitrogen application,the allocation rate of P,K and Cl were reduced.[Conclusion] In tobacco production,it is necessary to pay attention to balance between and nitrogen fertilizer other nutrient elements.关键词
