对张家界市3个主要产烟县(区)298个土壤样品的养分进行了分析,结果表明:烟区土壤pH值、有机质含量分别为6.4、23.3 g/kg,适宜于优质烟叶的生产;土壤交换性钙与有效硫、锰、铁、铜含量丰富,分别达到了9.4 cmol/kg、26.3 mg/kg、41.8 mg/kg、22.8 mg/kg和0.93 mg/kg。土壤速效氮、磷、钾、镁、锌、钼和硼含量分别为112.6 mg/kg1、6.4 mg/kg、206.1 mg/kg1、.6 cmol/kg、1.4mg/kg、0.18 mg/kg和0.16 mg/kg,这些养分均存在不同程度的缺乏。因此,在张家界市烟区烟草施肥上,除施用氮、磷、钾肥外,还需注意镁、锌、钼、硼等中、微量元素肥料的施用。
The results showed that soil pH value and organic matter content were 6.4 and 23.3 g / kg, respectively, which were suitable for the production of high quality tobacco leaves. Soil Exchangeable calcium and available sulfur, manganese, iron and copper were abundant, reaching 9.4 cmol / kg, 26.3 mg / kg, 41.8 mg / kg, 22.8 mg / kg and 0.93 mg / kg, respectively. The contents of available N, P, K, Mg, Zn, Mo and B in soils were 112.6 mg / kg1,6.4 mg / kg, 206.1 mg / kg1, .6 cmol / kg, 1.4 mg / kg, 0.18 mg / kg and 0.16 mg / kg, these nutrients are present in varying degrees of lack. Therefore, in Zhangjiajie tobacco area tobacco fertilization, in addition to the use of nitrogen, phosphorus and potassium fertilizer, but also pay attention to magnesium, zinc, molybdenum, boron, etc., the application of trace element fertilizers.
