| 摘 要： | 通过对恩施烟区272个土壤样品所进行的测定,评价了植烟土壤养分状况。结果表明,全州90%以上被调查土壤适宜种植烟草,50%的样品有机质含量较为适宜,近35%的样品有机质含量偏高,60%土壤全氮适宜。近60%的土壤碱解氮偏高,77.65%的土壤速效磷含量适中且部分偏高,但仍然有近23%的土壤速效磷含量偏低或缺乏;60%以上被调查土壤平均速效钾含量偏低,且区域间差异较大。土壤普遍缺镁,72.06%的被调查土壤交换性镁含量低于0.4 cmol/kg,变异系数为84.51%;30.51%的被调查土壤缺硼,56.99%的土壤存在缺硼风险;全州范围内大多数土壤有效锌含量适宜,部分偏高,但含量差异大,变异系数高。 |

| Abstract: | 272 of soil samples were collected from tobacco planting areas in Enshi.Soil pH,organic matter and macroelements were determined.The results indicated that about 90% of the soil pH was suitable for tobacco growth.In term of soil samples,50%,60% and 77.65% of soil organic matter,total N and available phosphorus content were suitable for tobacco growth.35% and 60% of the soil s were found with relatively higher levels of the soil organic matter and available N.Nearly 23% of the soils available phosphorus cont... |
