Analysis on variance and correlation of mainly shrub nutrients on karst areas in Southwest Guizhou

Abstract

Abstract: Six nutrient contents of 3 families with 19 genera and 27 species of fodder shrubs were measured in order to select suitable fodder shrubs to grow in the karst areas in Southwest Guizhou. And thereby promote the development of local animal husbandry and increase the income of farmers, then dates are made quantitative and correlation analysis. 1) Indigofera pseudotinctoria and Broussonetia kazinoki meet the requirements of a typical protein feed. 2) Mean values of ASH and NFE showed extremely significant difference among three families: The Moraceae had significantly higher ASH content than the other two families. The Leguminosea had significant lower NFE content than the Moraceae and Rosaceae; 3) There were high negative correlation coefficients between CF and NFE,EE,CP,and ASH,so the CF content strongly affects the overall nutritional value of fodder shrubs.
