按照现代生态学的观点,可以把农业生产看成是一个整体,一个系统。由此而来,农业生产的过程就必然要反映生态系统的一般规律。这种规律,表现在如下两方面:其一是体现系统的整体观。系统内部农业生物与农业环境众多环节(成分)之间存在着相互促进又相互制约的网络关系。农业生产量的获得是系统内部所有环节(成分)共同作用的结果,人为的农业生产技术措施的合理性、科学性必须体现对系统的整体具有促进作用。其二是遵循系统物质循环与能量转化规律。农业生产量是来自系统内部所具有相应的物质基础,为了获得农业的持续高产,就必须为系统创造、提供足够的物质和能量,实现系统内部物质循环和能量转化的动态平衡。所以,我们有必要从了解农业生态系统的一般规律着手,掌
According to modern ecology, agricultural production can be viewed as a whole and as a system. As a result, the process of agricultural production is bound to reflect the general laws of the ecosystem. This law, manifested in the following two aspects: First, reflect the overall concept of the system. There are interdependent and restrictive network relationships among many links (components) between agricultural biological and agricultural environments within the system. The acquisition of agricultural production is the result of the joint action of all the components (components) within the system. The rationality and scientific nature of the technical measures for agricultural production must be manifested in promoting the overall system. The second is to follow the system of material circulation and energy conversion law. Agricultural production comes from the corresponding material base within the system. In order to achieve continuous high-yielding of agriculture, it is necessary to create, provide enough material and energy for the system to realize the dynamic balance of material circulation and energy conversion within the system. Therefore, we need to understand and understand the general rules of agroecosystem
