烟草常用有机肥主要成分分析及质量评价研究

为对烟田常用有机肥质量评价和合理使用有机肥料提供科学依据，对烟草常用有机肥主要成分进行分析，将有机肥分类并进行质量评价，有机肥主成分主要为碳因子、氮因子及磷因子。5类有机肥划分为4个质量等级：1级豆饼，氮、磷、有机质含量及有机营养物质含量均较高；2级黑麦草、甘薯藤，氮含量中等，有机质及有机营养物质含量高；3级猪粪、鸡粪，氮、磷含量高，有机营养物质含量低；4级牛粪、麦秸秆、玉米秸等，氮、磷、有机质及有机营养物质含量均不丰富。烟草生产实践中应根据土壤实际条件合理施用各类有机肥。

Research on Principal Component Analysis and Quality Evaluation of Organic Fertilizer Commonly Used in Tobacco

In order to provide the scientific basics for quality assessment of organic fertilizer commonly used in tobacco as well as rational use of organic fertilizers,this article analyzed the main components of organic fertilizer commonly used in tobacco,classify as well as evaluate the quality of the organic fertilizer,the main components of these organic fertilize were carbon,nitrogen and phosphorus factor.Five types of the organic fertilizer was divided into four quality levels：the first level was cake that contains of high phosphorus,nitrogen,organic matter and nutrients;the second level was ryegrass and sweet potato vine that contains of medium nitrogen,high organic matter and organic nutrients;the third level was pig manure and chicken manure,the feature of this level was high content of nitrogen and phosphorus but low organic nutrients;the last level was cow dung,wheat straw,corn stalks and so on,the feature of this level was poor content of nitrogen,phosphorus,organic matter and organic nutrients.We should take rational application of various types of organic fertilizer based on the actual soil conditions.
