Abstract: In order to develop green food, reduce the use of chemical fertilizer and reduce the use of pesticide, realize "double-reduction" and synergism, that can improve safety and quality of products, protect the ecological environment and promote the healthy and steady development of strawberry industry. Build on the experience of research and practice in production, and coupled with production experience of Japan and other countries, the author summarized the green development goal of greenhouse strawberry and the key technology of "double-reduction" and synergism, then technology goals were established. Six key technologies were discussed in the paper, include the technique of healthy seedling cultivation, soil amendments for the remediation of soils with continuous cropping obstacle, ecological control technique in agriculture, trapping and killing pests utilizes technology of physics and chemistry, biological control, and chemical control of low remain.
