摘要: 對紅云集團原料基地（云南,、貴州和福建省）23 個縣（區(qū)）植煙土壤的中,、微量元素含量狀況進行了普查,。結果表明，3 個基地縣（區(qū)）中,，除云南騰沖縣植煙土壤有效B 含量為0.52 mg/kg,，略高于缺B 臨界值0.50 mg/kg 外，其余22縣（區(qū)）均處于缺B 或潛在缺B 狀態(tài),，此外,，整個紅云集團原料基地共有89.13%的植煙區(qū)土壤屬于缺B 或潛在缺B 區(qū)域，急需補充B 肥,；23 個基地縣（區(qū)）除有效B 外,，其余中、微量元素含量總體豐富,，但仍有局部植煙區(qū)域處于中,、微量元素缺乏或潛在缺乏狀態(tài)，需要合理補充相應的中,、微量元素肥料,；23 個基地縣（區(qū)）植煙土壤的中、微量元素現狀通過系統(tǒng)聚類法可分為5 種類型,。Abstract: The soil medium element and microelement contents in material base of Hongyun Tobacco Group were studied in this study. The results showed that among 23 raw material base counties, Tengchong exhibited the available B content of 0.52 mg/kg, little higher than the critical value of 0.50 mg/kg, while the other 22 counties were lacking in B or potentially lacking in B. Furthermore, 89.13% of the tobacco planting soil lacked B or potentially lacked B, so additional supplyment of B fertilizer was required. Secondly, except for B, the contents of the other medium elements and microelements were abundant, but some regions belonged to lacking or potentially lacking area, where additional application of medium elements and microelements was needed. Thirdly, the conditions of medium elements and microelements in 23 material base counties could be classified into 5 types by systematic cluster analysis.
