【目的】研究在中耕培土时期,基施和追施不同配方富钾土壤调理剂对烤烟生产的影响。【方法】利用木本泥炭、矿物钾肥(水热法)和钙镁磷肥代替常规施肥中的硫酸钾和硝酸钾,研究其对烤烟根区土壤pH值、速效钾、缓效钾、烟叶品质和烤烟经济状况的影响。【结果】不同配方富钾土壤调理剂可以有效的提高烤烟根区土壤pH值,并使其保持在5.5 ~ 6.5之间,效果为T5 >T3 >T4 >T2 >T1,其中木本泥炭基腐植酸钾(基肥)和钙镁磷肥配施效果最佳;追施木本泥炭基腐植酸钾、矿物钾肥(水热法)和钙镁磷肥均能显著提高土壤中速效钾、缓效钾含量以及中上等烟比例,其中木本泥炭基腐植酸钾(基肥)与矿物钾肥(水热法)1∶ 3施用效...

【Objective】The purpose of this paper was to study the effects of base and topdressing with different potassium-rich soil conditioners on tobacco production during the period of soil cultivation.【Method】In this study,wood peat derived potassium humate,mineral potash(hydrothermal method)and calcium magnesium phosphate fertilizer were used instead of KNO_3 or K_2SO_4 on the base,to study their effects on soil pH,available potassium,slow potassium,tobacco leaf quality and economic status of flue-cured tobacco.【Result】The results showed that b...
