Preliminary Report on the Ecological Benefits of Intercropping Pattern for Cocoa and Teucrium manghuaense
In tercropping pattern for Teucrium manghuaense and cocoa can effectively improve the ecological conditions of the cocoa plantation.When the shading is between 800 lx and 8 430 lx,it is appropriate for the growth of Teucrium manghuaense.Compared with the monoculture,the land equivalent ratio is greater than 1.46 at the intercropping model of cocoa/Teucrium manghuaense,showing greater advantage of yield.Then contents of amino acids and minerals composition in different parts of Teucrium manghuaense were analyzed.The results showed that amino acid content in lower leaves was up to 13.8 g/hg,the content of Mg and Cu was up to 27.27 mg/g,and 2.81 mg/g in leaves,respectively,and the content ranking was upper leaves middle leaves lower leaves.What's more,the content ranking of Zn,Fe and Mn was upper leaves middle leaves lower leaves,and the upper contents for Zn,Fe and Mn was 475 mg/g,16.72 mg/g and 12.5 mg/g,respectively.In conclusion,this study can provide scientific data for improving the quality of raw materials of Teucrium manghuaense,at the same time,can make full advantage of land resources and effectively improve the economic benefits of the unit area.
