Key measures of eco-agricultural practices include landscape design at landscape level, circulation system design at ecosystem level and biological relationship design at community or sub-community level. Landscape design includes biological conservation design, resources utilization framework design, ecological safety design, and aesthetic landscape design. Circulation system design includes field circulation system,...

Following the basic organization hierarchy of biology, eco-agricultural models can be classified into the following fundamental classes: landscape model (at landscape level), in which agricultural land arrangement pattern is essential; cycling model (at ecosystem level), in which the core model is linked to different compartments of agro-ecosystems through energy and...

A technical package for eco-agriculture is the assembly of multiple techniques for a functional and goal-oriented agro-ecosystem management. The resources can originate from traditional agro-practices, modern agro-practices and high-tech innovations. There are inseparable, compatible, or incompatible relationships between a single technique and a specific agro-ecosystem. Also, there are mutually dependent,...

Crop row spacing in intercropping systems affects interactions of crop species and subsequent crop yields. In a field experiment, the response of crop yield to different maize row spacing (0-80 cm) in pea/maize intercropping system was investigated. The results showed that land equivalent ratio (LER) of each treatment exceeded 1,...
