摘要
【目的】为了解红河烟区土壤养分丰缺状况。【方法】共采集红河烟区不同县(市)植烟土壤样品881份,并对样品的6项土壤养分指标进行测定分析。【结果】7个县(市)植烟土壤pH平均值除石屏县稍低外,其他县(市)植烟土壤pH平均值均适宜烤烟生长(5.5~7.0)。植烟土壤的有机质平均含量除建水县(23.66 g/kg)和泸西县(24.93 g/kg)在适宜烟草生长的含量范围内,其余县(市)均高于适宜有机质含量(15~25 g/kg)。碱解氮低含量(AN<100 mg/kg)比例最高的是建水县(52.63%),土壤速效磷偏高含量(≥40 mg/kg)比例最高的是石屏县(37.95%),土壤速效磷偏低含量(<20 mg/kg)比例最高的是个旧市(90.47%),土壤水溶性氯过高含量(>45 mg/kg)比例最高为建水县(6.57%)。【结论】红河烟区土壤养分肥力中等偏上,适宜烤烟种植。为改善土壤养分状况和烟叶品质,建议在土壤适宜性较差的植烟县(市)结合烟叶品质调整现有施肥方案。
【Objective】The present paper aimed to understand the status of soil nutrient abundance and deficiency in Honghe tobacco-growing area.【Method】881 tobacco-growing soil samples were collected from different counties(cities)in Honghe tobacco-growing area,and 6 soil nutrient indicators were determined and analyzed.【Result】The results showed that the average pH value of tobacco-growing soils in 7 counties(cities)was within the suitable growth range of flue-cured tobacco(5.5-7.0),except Shiping county,which was slightly lower.Except for Jianshui(23.66 g/kg)county and Luxi county(24.93 g/kg),the average content of organic matter in tobacco-growing soils in other counties(cities)was higher than that in suitable tobacco-growing soils(15-25 g/kg).The highest proportion of low content of alkali-hydrolyzed nitrogen(AN<100 mg/kg)was Jianshui county(52.63%),the highest proportion of available phosphorus(>40 mg/kg)was Shiping county(37.95%),the lowest proportion of available phosphorus(<20 mg/kg)was Gejiu city(90.47%),the highest proportion of excessive water-soluble chlorine(>45 mg/kg)was Jianshui county(6.57%).【Conclusion】The soil nutrient fertility in Honghe tobacco growing area belongs to the middle and upper level,which was more suitable for flue-cured tobacco cultivation.It is suggested that tobaccogrowing counties(cities)with slightly poor soil suitability should adjust the existing fertilization schemes according to tobacco leaf quality in order to improve soil nutrient status and tobacco leaf quality.
