I. Scale and industrialization of greenhouses
        Greenhouse greenhouse agriculture is a high-input, high-output, high-efficiency industry. Only a considerable scale can help standardized and standardized production, and it is possible to form an influential brand, thereby occupying the market and making resource advantages effective. Development and sustainable use, while bringing huge economic benefits. Therefore, governments at all levels should formulate preferential policies on the basis of good planning, increase investment, support and cultivate large-scale greenhouse agricultural bases, accelerate the development of facility agriculture and enterprises, and promote the industrialization of greenhouse greenhouse agriculture.
        Large-scale greenhouses can reduce construction costs. Compared with the model greenhouse, the unit construction cost of a large continuous greenhouse is lower. For example, the construction of a greenhouse of 2h㎡ saves an average of 20% of the cost per square meter of a greenhouse of 0.3h㎡.
Factoryization
        The industrialized production of agricultural products is an important means and approach of rural urbanization. Only factory production can make animals and plants not restricted by regions and climates, and produce according to people's wishes and requirements throughout the year to achieve high quality, safety, and high yield, and workers can perform labor-saving and easy operations in a comfortable environment. In addition, the waste can be recycled to maintain a good ecological environment. However, the main problem with the current factory greenhouses is the high cost of construction and operation.
 

Third, reduce the cost of greenhouses

             Reducing the cost of greenhouses requires comprehensive measures.
           1. Greenhouse greenhouse agricultural engineering standardization and standardization
Greenhouse greenhouse agricultural engineering standardization and standardization include greenhouse facilities, equipment and agricultural production. Facility buildings and supporting facilities have specifications and standards for design, structure, installation, construction, and use, which can greatly reduce construction and operating costs; establishment of norms and standards for facility agricultural production, reducing agricultural product production costs, and improving the quality of greenhouse greenhouse agricultural products And sales revenue.
         2. Develop high-quality, cheap and durable new materials
        Rigid plastics will gradually replace glass, which will be less harmful when earthquakes and typhoons occur.
         3. Energy saving
        In order to save energy, a three-layer transparent plastic film has been developed as a covering material for greenhouses. Pressurized air is passed into the outer interlayer to support the cover. The inner interlayer passes circulating water to absorb absorbed solar energy (water temperature during the day). It can be stored in the underground soil through underground pipes, and the thermal energy stored in the soil is used for the insulation of the greenhouse at night. With different regions, climates and crops.
          4. Introduce and develop new planting technologies
       If soilless cultivation is used, the yield per unit area can be greatly increased. Tomatoes can be grown at an annual yield of 60.8 tons per hectare, which is 11 times higher than traditional planting methods. Take Canada as an example, the country consumes an average of 9.1 kg of tomato per person per year, and the total population of 20 million people in the country consumes 182,000 tons per year. If soilless cultivation is adopted, the land of 520hm2 can meet the needs of the whole country. The table shows a comparison of the yield per mu of soils and soilless cultivation for various crops.

       In order to make employees work more comfortable, the environment must be clean and hygienic. Through the improvement of working space, air permeability, and stability of temperature and humidity, the environmental quality of the greenhouse can be improved, including the environment, working conditions, visual conditions, auditory conditions, and auditory conditions.

        Greenhouse production and operation machinery mainly includes small agricultural machinery for greenhouses, supporting facilities for building facilities, and other supporting products. Greenhouse small farm machinery can only perform mechanical operations such as ploughing, planting, filming, wiping, grafting, cropping, furrowing, fertilizing, spraying, and harvesting in the greenhouse. Especially, the harvesting operation is the most complicated and labor-intensive. Process, robotic harvesting may be a good choice to solve this operation. First, crops with large planting volume, short harvest period, heavy workload and hard work, such as strawberries and fresh cut flowers, should be addressed first.

6. Multidisciplinary participation
       The development of modern greenhouse greenhouse facilities agriculture requires multidisciplinary collaborative research such as horticulture agriculture, agroecology, plant protection and agricultural engineering, in order to develop a complete set of excellent equipment and supporting technologies, and form a strong competition with similar international products. The industrialization system of facility agriculture includes equipment, facilities and environmental engineering, seed innovation engineering, factory-based production technology, post-production processing and processing engineering, etc. It is a one-stop system for design, manufacturing, production, and sales, and integrated agriculture, science, and trade. In order to make the entire system run smoothly, it is necessary to establish a social service system, a production organization system, a talent training system, and a commodity supply and demand information system. Therefore, it is necessary to strengthen multi-industry collaboration.
        Greenhouse facility agriculture is the integration of modern biotechnology and engineering technology, and is a symbol of agricultural high technology. Greenhouse agriculture has continuously introduced new technologies, which can accelerate the growth rate of greenhouse crops, shorten the growth cycle, increase yield, and improve quality. For example, soilless cultivation is changing the traditional cultivation methods of greenhouse greenhouse cultivation. Soilless cultivation is not limited by region and season, water saving, energy saving, labor saving, fertilizer saving, high crop yield, good quality, high efficiency, clean and sanitary, reducing soil pollution, preventing continuous cropping obstacles, reducing soil-borne pests and diseases Aspect advantages. Another example is the use of gas fertilizers, which can cultivate strong seedlings, accelerate crop growth, increase yield, improve quality, and improve crop disease resistance. The plug tray seedling technology saves labor and cost, and the cost can be reduced by 30% -50%, which improves the land utilization rate and effectively increases the production area of the protected area.
