At last, it gives the prospection about the application of Si fertilizer in the sustainable and organic agriculture.展开更多

Enlightenment： this knowledge helps avoid misunderstanding of educational philosophy, which is not only a type of theoretical philosophy, but also a practical philosophy; teachers need to construct a proper philosophy of personal education of their own and enhance their professionalism and specialism while improving their humanistic quality and professional sentiment; great efforts should be made to create an educational community to exert the influence of philosophy of public education, and to promote the healthy development of educational activities.展开更多

In order to achieve ideal living environment, people believed that they should use, repair, and improve the nature in an active but abstemious way, and a complete system of design theories and techniques gradually developed. The intellectual architects, in particular, pioneered the practical and theoretical developments, especially those in Tang dynasty made extraordinary contributions. Among them, Yuan lie （元结） and Liu Zongyuan （柳宗元） were particularly outstanding. They had different experiences but similar achievements in Yongzhou area, which was a remote, less-developed region but with beautiful landscapes. In this paper, the planning and design practices of these two intellectual architects were examined and compared. Their principles and methods of Design With Nature were summarized. Also, the historical influence of their works and its contemporary value were briefly discussed at last.展开更多

In order to improve the practice teaching quality of public security practice, we should apply modern instructional design theory. Aiming at the problems existing in the practice teaching of public order, we design a practice teaching system for public security. In the process of practice teaching design of public order, we should pay attention to the starting point of the practice teaching, design of teaching objectives, design of practical teaching content, design of practical teaching mode and evaluation of the practice teaching of public security.展开更多
