How to plan the popular science education and agricultural science and technology demonstration park

How to plan the popular science education and agricultural science and technology demonstration park in the ecological park? Shanhe Shuiyi Planning and Design Institute believes that through the construction of agricultural museums and exhibition halls in the park, environmental protection education and popular science education will be carried out for tourists and primary and secondary school students. At the same time, in response to the needs of China's agricultural development and agricultural restructuring, the park should be planned as an agricultural technology exchange center and training base as well as a college student practice base, reflecting the tourism science popularization function of the sightseeing agricultural ecological park, and further creating a high-quality image of tourism products.

The development of tourism agriculture and agricultural science popularization is unified, and tourism science popularization is the unified product of tourism agriculture and agricultural science popularization. Tourism science popularization is an emerging type of science popularization that develops and utilizes agricultural resources through the modern enterprise management mechanism. Its introduction will solve many bottlenecks that currently plague the development of modern tourism agriculture and popular science in China, alleviate the heavy pressure of too many objects of agricultural popular science in China, and create a good environment for the development of agricultural and popular science in China.

For example, through the establishment of popular science education centers such as the Agricultural Science Museum and the Modern Agricultural Science and Technology Expo Area in the ecological park, the history of agriculture and the current situation of agricultural development can be introduced to visitors, and agricultural knowledge and environmental protection education can be strengthened. It is also possible to set up a modern agricultural science and technology research center in the modern agricultural science and technology expo area, and use bioengineering methods to cultivate various crops and form characteristic agriculture. In this way, the ecological park can provide a base for popular science education in the local and surrounding areas, a place for popular science education for universities, colleges and universities, and primary and secondary school students, as well as a place for various exhibitions and large-scale agricultural technology exchanges, academic conferences and agricultural technology training.

The exemplary role of ecology and popular science education and agricultural science and technology are not strong. When the article proposes the planning of the sightseeing agro-ecological park. In the planning, the undulating natural slopes and culverts are mainly used to discharge rainwater into nearby water bodies. All artificial water supply.

a, the nutrients contained in the farm fertilizer are more and less in the source search, and the nutrients of the fertilizer are relatively single but the content is high, and the mixed use of the two can improve the efficiency, so the practice is appropriate;

b. Adding an appropriate amount of carbon dioxide to the greenhouse can promote the photosynthesis of plants, thereby increasing the yield, so it is appropriate;

c. The combination of planting, breeding and biogas production can not only improve the environmental health of rural areas, but also facilitate the integration and utilization of resources and increase agricultural output.

d. When ammonium nitrate and hydrated lime are mixed, the two will undergo a chemical reaction to generate volatile ammonia and reduce the fertilizer efficiency, so the practice is inappropriate

Therefore, choose D
