摘要
2015年对永州产烟乡镇(78个) 689个植烟土壤的大量元素的全量和有效养分进行了调查分析,结果表明:土壤氮贮存及有效供应水平较高,土壤磷贮存及有效供应水平适宜,土壤钾贮存及有效供应相对不足。聚类分析将全区聚合为五大养分类型,提出了各类型土壤养分特征及对应施肥策略。
In 2015,the total amount and available nutrients of primary nutrients of 689 soils in all tobacco-producing towns(78)of Yongzhou were investigated and analyzed.The results showed that the storage and effective supply level for nitrogen nutrient in soils were higher,and appropriate for soil phosphorus storage and effective supply level,but relatively insufficient for soil potassium.Five major nutrient types in the whole region of tobacco-planting soil of Yongzhou were aggregated by cluster analysis.Nutrient characteristics of different types and corresponding strategies of fertilization were further proposed.
