设计和布局生态农业时,可从生态农业的平面设计、垂直设计、时间设计、食物链设计等方面着手。这里主要探讨生态农业的食物链设计问题。生态农业的食物链设计是指根据当地实际情况和生态学原理,合理设计农业生态系统中的食物链结构,以实现对物质和能量的多层次利用,提高农业生产的效益。食物链设计的重点之一是在原有的食物链中引入或增加新的环节。例如,引进捕食性动物控制有害昆虫的数量,增加新的生产环节,将人们不能直接利用的有机物转化为可以直接利用的农副产品等。【实践目的】1.初步学会根据当地农业生产情况,设计良性循环的农业生态系统。2.培养学生查阅相关资料和知识、参与社会实践、理论与实践活动
Design and layout of ecological agriculture, from ecological agriculture, graphic design, vertical design, time design, food chain design and so on. Here mainly discusses the design of ecological agriculture food chain. The design of food chain in eco-agriculture refers to the rational design of the food chain structure in agro-ecosystem according to the local actual conditions and ecological principles so as to realize the multi-level utilization of material and energy and improve the efficiency of agricultural production. One of the key points of food chain design is to introduce or add new links to the original food chain. For example, the introduction of predators to control the number of harmful insects, adding new production processes, the people can not be directly used by the conversion of organic matter can be directly used by agricultural and sideline products. [Practical purposes] 1. Preliminary learn to design a virtuous circle of agricultural ecosystems based on local agricultural production. 2. Training students access to relevant information and knowledge, participate in social practice, theory and practice activities
