摘要：

为了查明贵州盘县主植烟区的土壤肥力状况，为土壤改良和烟草平衡施肥提供理论依据，对该县的3个主植烟区140个土壤样品养分进行检测分析。结果表明：盘县植烟土壤pH平均为6.12，处于弱酸性至中性范围；有机质、全氮、全磷含量总体上较丰富，分别为34.38 g/kg、2.22 g/kg和1.12 g/kg；但速效氮、速效磷、全钾和速效钾含量基本处于中等至偏低水平，分别为39.27 mg/kg、8.78 mg/kg、9.69 g/kg和139.98 mg/kg；土壤交换性钙含量处于1147.88~5854.67 mg/kg之间，土壤交换性镁含量处于46.66~708.17 mg/kg范围，二者含量均高于临界指标；土壤有效锌含量范围为0.57~5.55 mg/kg，94.29%的样品高于缺锌临界值(<1.00 mg/kg)。水溶性氯含量处于7.43~39.23 mg/kg之间，95.71%的土壤样品处于适宜的范围内。土壤有效钼含量范围为0~0.59 mg/kg，80.00%的样品高于缺钼临界值(<0.10 mg/kg)。土壤有效硼含量在0.17~1.25 mg/kg之间，68.57%的样品低于缺硼临界值(<0.50 mg/kg)。建议盘县主植烟区在平衡施肥时应注重控氮、补施磷钾、增施钼和硼。

Abstract:

In order to investigate the soil fertility situations to provide the theory basis on soil improvement and balanced fertilization in main tobacco-growing areas of Panxian region Guizhou province, 140 soil samples from 3 main tobacco-growing areas were analyzed. The results showed that the average pH value was 6.12, which was in an appropriate amount for tobacco growth. The contents of organic matter, total nitrogen, total phosphorus were rich in general, 34.38 g/kg, 2.22 g/kg and 1.12 g/kg respectively. But the contents of available nitrogen, available phosphorus, total potassium and available potassium in the medium to low levels, 39.27 mg/kg, 8.78 mg/kg, 9.69 g/kg and 139.98 mg/kg respectively. The contents of soil exchangeable calcium and exchangeable magnesium were 1147.88-5854.67 mg/kg, 46.66-708.17 mg/kg respectively, both of them were higher than the critical index. The range of soil available zinc content was 0.57-5.55 mg/kg, 94.29% of the samples was higher than the critical index (<1.00 mg/kg). The range of water-soluble chloride content was 7.43-39.23 mg/kg, and 95.71% of soil samples was lower than the critical index (30.00 mg/kg). The range of soil available molybdenum content was 0-0.59 mg/kg, and 80.00% of soil samples was higher than the molybdenum critical index (<0.10 mg/kg). The range of soil available boron content was 0.17-1.25 mg/kg, and 68.57% of samples below the boron critical index (<0.50 mg/kg). It was suggested that controlling nitrogen fertilizer, supplying phosphorus and potassium fertilizer and increasing molybdenum and boron fertilizer should be paid more attention in balanced fertilization in Pan xian tobacco-growing areas.
