摘要：

为明确广东梅州主要烟区土壤的养分丰缺状况,该研究在梅州6个烟叶主产县,采集83个土壤样品,对植烟土壤养分丰缺状况进行调查,以期为烟区土壤改良、合理施肥提供理论依据和技术支持。结果表明:植烟土壤整体偏酸;土壤有机质含量整体丰富,适宜、偏高、较高比例分别为8.4%、32.5%和59.1%;土壤全氮含量整体偏高,适宜、偏高、较高比例分别为4.8%、24.1%和71.1%;土壤有效磷含量偏高、较高比例分别为2.4%和97.6%;土壤速效钾含量偏低、适宜、偏高、较高比例分别为13.3%、24.1%、25.3%和37.3%。因此,在生产实际中应减少肥料的施用量,合理利用土壤调理剂改良酸碱性。

Abstract:

In order to clarify the nutrient abundance and deficiency of soil in the main tobacco areas of Meizhou, Guangdong, 83 soil samples were collected from 6 major tobacco producing counties in Meizhou to investigate the nutrient abundance and deficiency of tobacco soil, in order to provide theoretical basis and technical support for soil improvement and reasonable fertilization in tobacco areas. The results showed that the soil was acidic as a whole. The soil organic matter content was abundant, and the proportions of suitable, high and higher were 8.4%, 32.5% and 59.1%, respectively. The soil total nitrogen content was generally high, and the proportions of suitable, high and higher were 4.8%, 24.1% and 71.1%, respectively. The high and higher proportion of soil available phosphorus content were 2.4% and 97.6%, respectively. The low,suitable, high and higher proportion of soil available potassium content were 13.3%, 24.1%, 25.3%, and 37.3%, respectively. Therefore, the amount of fertilizer should be reduced in the actual production, and the soil conditioner should be used rationally to improve the acidity and alkalinity.
