    鄂西南植烟土壤养分状况分析

    Analysis on Soil Nutrients of Tobacco-growing Areas in Southwest Hubei

    • 摘要: 对鄂西南8个产烟县(市)进行了土壤取样调查分析。结果表明,鄂西南烟区14%的土壤存在酸化趋势;约50%土壤的有机质和86.5%土壤的碱解氮含量偏高;28%的土壤非常缺磷,63.5%的土壤缺钙;58.5%的土壤缺钾,其中20.1%的极度缺钾;89%的土壤缺镁;88.2%的土壤缺硼,其中54.4%的严重缺硼。因此,应采取相应措施调节酸碱度,严格控制氮肥用量,重视普钙(过磷酸钙)、钾肥、镁肥和硼肥的施用。该烟区79.1%的土壤不缺锌,因此,缺锌不是该烟区烟叶生产的主要障碍,但需要关注土壤有效锌含量的变化趋势。

       

      Abstract: Soil samples from eight tobacco production areas in southwestern Hubei Province were analyzed. The results indicated that 14% of the soil experienced different levels of acidification. 50% and 86.5% of the soils were found with relatively higher levels of organic matter and available nitrogen, respectively. 63.5%, 58.5%, 89% and 88.2% of the soils were deficient in calcium, potassium, magnesium, and boron, respectively, including 28%, 20.1%, and 55.4% of the soils extremely poor in phosphorus, potassium, and boron, respectively. Thus measures should be taken to control soil pH and nitrogen fertilizer rate, and calcium, potassium, magnesium and boron fertilizer should be applied. 79.1% of the soils were not deficient in zinc, but we should pay attention to changes of soil zinc contents
