The invasive plants in Guangdong are dominated by Mikania micrantha, Eichhornia crassipes, Alternanthera philoxeroides, Eupatorium odoratum, and Wedelia trilobata. It is an important way for treating the invasive plants by exploring the prevention methods and making ful use of the characteristics of the invasive plants, and it is of great significance to prevent and utilize alien species in a scientific and effective way in order to control the invasive plants with minimal cost.展开更多

The instrumentalization of traditional moral education mode,mechanical preaching and the characteristics of knowledge education are the important reasons for the emergence of problems. The agricultural and forestry colleges and universities must realize the transformation and innovation of moral education mode,reshape the main position of moral education of college students,rebuild the core value of moral education which pays close attention to the growth of individual life,and reconstruct the way of realization of moral education in colleges and universities.展开更多
