对隆阳烟区215个植烟土样的14项指标进行了分析。结果表明:隆阳多数土壤pH值和有机质含量适中,速效磷含量充足,交换性钙、交换性镁、有效铜、有效锌和有效硫含量较为丰富,碱解氮和速效钾含量不足,普遍缺硼和锰;将10个植烟乡镇按土壤养分特点系统聚类分析划分为3类,其中:瓦窑、水寨、瓦马、杨柳、蒲漂、西邑植烟乡镇的速效磷、有效锌、有效硼、有效硫和水溶性氯含量较高,辛街的有机质、pH值、碱解氮、交换性镁、有效铜和有效锰平均含量较高;汉庄、丙麻、瓦渡的速效钾、交换性钙和有效铁平均含量较高;并提出了不同的施肥策略。
A total of 215 indicators of tobacco planting soil in Longyang were analyzed. The results showed that most of the soil had the moderate pH value and organic matter content, adequate available phosphorus content, abundant exchangeable calcium, exchangeable magnesium, available copper, available zinc and available sulfur, and the content of available nitrogen and available potassium was insufficient, Boron and manganese. According to the characteristics of soil nutrients in 10 tobacco-producing townships, the cluster analysis was divided into 3 categories, among which, available phosphorus, effective zinc, Available boron, available sulfur and water-soluble chlorine content were higher. The content of organic matter, pH value, alkaline hydrolysis nitrogen, exchangeable magnesium, available copper and available manganese in Xinjie Street were higher than that in Xinzhuang, , Exchangeable calcium and high average iron content; and put forward different fertilization strategies.
