[A study on soil suitability for growth of rhizome of Curcuma longa L].
OBJECTIVE
To seek for the type of soil that influences favorably the yield and quality of Curcuma longa.


METHODS
Field contrast control experiment, correlation analysis, path analysis and cluster analysis were used.


RESULTS
The rhizome yield and quality of Curcuma longa. varied greatly with the types of soil texture. There are clear correlations among the soil factors, as well as between the soil factors and the rhizome yield and quality of the plant. A regression equation of the rhizome yield and soil factors has been built up.


CONCLUSIONS
The soil suitable for growing Curcuma longa. can be classified into three types according to the results of correlation analysis and cluster analysis.
