摘要
采用相关以及多元线性回归分析法,对植烟土壤中的全磷、速效磷、缓效磷与烟叶化学成份及评吸质量的关系进行研究,找到其相关性,得出相应的定量关系式,并评价了磷形态与烟叶化学成份及评吸质量作用的显著水平。
Correlation analysis and multiple linear regression were performed to find the relationship between total phosphorus, quick - acting phosphorus, and slow - acting phosphorus of soils and tobacco compositions and smoking quality, to derive correlation coefficients and quantitative formulas for such relationship, and thus guiding the cultivation of high quality tobacco.
