摘要
对红云集团原料基地(云南、贵州和福建省)23个县(区)植烟土壤的中、微量元素含量状况进行了普查。结果表明,3个基地县(区)中,除云南腾冲县植烟土壤有效B含量为0.52 mg/kg,略高于缺B临界值0.50 mg/kg外,其余22县(区)均处于缺B或潜在缺B状态,此外,整个红云集团原料基地共有89.13%的植烟区土壤属于缺B或潜在缺B区域,急需补充B肥;23个基地县(区)除有效B外,其余中、微量元素含量总体丰富,但仍有局部植烟区域处于中、微量元素缺乏或潜在缺乏状态,需要合理补充相应的中、微量元素肥料;23个基地县(区)植烟土壤的中、微量元素现状通过系统聚类法可分为5种类型。
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.
