In our country to develop ecological agriculture, there are several main ideas?

First, the use of three-dimensional planting to improve resource utilization. Three-dimensional planting is in a semi-artificial or artificial environment to simulate the natural ecosystem principles of production planting. It cleverly composed of agro-ecosystem space-time structure, the establishment of three-dimensional planting and breeding pattern, composed of a variety of biological **** life and mutually beneficial relationship, the rational use of spatial resources, and the use of material and energy multi-level transformation means, prompting the material cycle of regeneration and the full use of energy, and at the same time, biological integrated prevention and control, less pesticides, to avoid the heavy metal pollutants or hazardous substances into the ecosystem, and finally To realize the combination of ecological and economic benefits, and to bring into play the wholeness and functional integration of the system.

Second, the development of water-saving dry farming. China is a country with a shortage of water resources, calculated on the basis of arable land area, the average mu of water resources is only half of the world average. The national average annual precipitation of about 650 millimeters, lower than the world average, and uneven spatial and temporal distribution of precipitation. The arid, semi-arid and semi-humid drought-prone areas in the north, where precipitation is below 600 millimeters, account for 56 per cent of the country's land area. In addition, although the annual precipitation in the hilly and mountainous areas of the south is relatively adequate, seasonal drought conditions often occur because of the topographical and geomorphological characteristics of the terrain, coupled with the concentration of rainfall periods, the inability to keep up with water-storage facilities and soil erosion, etc., and the constraints on agricultural production by water resources are very great. To make China's agriculture to a new level, we must strengthen the basic construction of farmland, the development of water-saving dry farming.

Third, the production of pollution-free agricultural products. Pollution-free agriculture is a brand-new concept put forward in the 1990s in China's agriculture and agricultural products processing field. It refers to the non-polluting areas or have eliminated pollution in the region, make full use of natural resources, to maximize the limit of exogenous pollutants into the agricultural production system, the production of non-polluting safe, high-quality, nutritious products, and at the same time, the production and processing does not cause harm to the environment. The core is agricultural products from a clean ecological environment, limiting the use of chemicals in the production process, processing in line with the appropriate operating procedures and food production.

Fourth, the development of white agriculture. "White agriculture" is based on cell engineering and enzyme engineering, the comprehensive utilization of genetic engineering to form the engineering agriculture. It has the characteristics of ecological agriculture, that is, the protection of natural resources and ecological environment. White agriculture is the use of microbial resources treasure trove, the application of science and technology for the development, the creation of microbial industrial type of new agriculture. Traditional agriculture uses the sun as a direct energy source and utilizes green plants to produce human food and animal feed through photosynthesis. Compared with traditional green agriculture, "white agriculture" has a very different basic form and production mode. Relying on artificial energy, "white agriculture" is not limited by weather and seasons, and can be produced on a large scale in factories all year round. Therefore, the development of microbial engineering science, the creation of soil-saving, water-saving, non-polluting environment, recyclable resources, industrial-type "white agriculture", is an important way of sustainable development of agriculture.

Fifth, the development of tourism ecological agriculture. Sightseeing eco-agriculture refers to eco-agriculture as the basis for sightseeing tours and recreational vacations as the main purpose, the use of agricultural resources, development and protection of a set of integrated, comprehensive consideration of the ecological reasonableness, technical feasibility, economic effectiveness, and strengthening of the agricultural sightseeing, recreation, entertainment, and education functions, the formation of a tertiary industry with the characteristics of a new mode of agricultural production and management, to go not only to promote the advantages of agricultural resources to the advantages of eco-tourism change. The advantages of agricultural resources to the advantages of ecotourism, but also conducive to the promotion of ecological environment advantages to the advantages of economic development to change the new way.
