In recent years, China has vigorously implemented the strategy of rural revitalization, and many projects such as rural complexes and modern agricultural parks have emerged. Through the construction of the projects, the integration of rural industries has been promoted, the development of agriculture and rural areas has been stimulated, the income of farmers has been increased. The spiritual life of people has been enriched and achieved the revitalization of the countryside. Facility agriculture represented by high-tech intelligent greenhouses, such as rural complexes and modern agricultural parks, has been widely used.
Disadvantages of traditional greenhouses
At present in China's rural and suburban areas, traditional greenhouses such as soil walls and brick-concrete greenhouses are the most common. These greenhouses have relatively simple structures and a lack of technical content. It is very common in the vast rural areas of China. Although this greenhouse is simple and low in cost, it is also very poor in terms of heat preservation capacity, pressure resistance capacity, temperature control management, and production efficiency. The area of the shed wall like soil wall is large, which affects the net planting area and has requirements on the soil quality. For example, if the wall is not properly protected, it will be easily washed away by rain and snow and affect the service life. The bamboo and wooden sheds have a simple skeleton structure and weak resistance to wind and snow and have columns in the interior, which affects the internal operating space. These low-end greenhouses require a lot of manpower and material resources in daily management such as seedling raising, pollination, temperature control, and picking. The production efficiency is very poor, staying in a backward stage, and it cannot meet the actual needs of modern agricultural industrialization.
Advantages of the new smart greenhouse
With the continuous development of China's agricultural technology level, especially in recent years, with the increase in international exchanges, the integration and introduction of foreign advanced greenhouse construction technology, soilless cultivation technology, and industrial planting concepts, combined with domestic production practices, in the production practice, a new intelligent greenhouse model suitable for China's actual situation has gradually formed, and the development of the ecological rural tourism industry has been taken into account. The new intelligent greenhouse has six obvious advantages in modern agricultural production.
1 Beautiful appearance and large space
At present, the new-type intelligent greenhouses generally adopt the current Venlo structure of the modern greenhouses in the world. Theoretically, they can be infinitely connected. In this way, the shape is very good-looking and the space is wide. Besides, this kind of greenhouses has a high land use rate and is suitable for mechanized operations and installation of various modern greenhouse equipment. Its skeleton and other materials used are generally produced by specialized factories, and they are strong and beautiful and are excellent in wind and snow resistance.
2 Wide application and strong expandable functions
The new intelligent greenhouse is generally designed in accordance with the greenhouse specifications, and common greenhouse equipment and machinery can be matched with it. Various greenhouse equipment can be selected and configured according to the actual needs of specific applications.
It can be made into high-tech vegetable demonstration gardens, plant factories, flower greenhouses, ecological sightseeing greenhouses, research-use greenhouses, nursery greenhouses, breeding greenhouses, and other forms.
3 High technical content and precise management
Various sensors in the new smart greenhouse can perform environmental monitoring of the temperature, light, soil humidity, carbon dioxide concentration, etc. in the greenhouse on time, and input the data into the intelligent control system of the greenhouse, make analysis and control, and generate data reports. Greenhouse environment accurate monitoring and remote intelligent control create an optimal environment for plant production.
4 Save labor and high production efficiency
We only need to set the technical parameters required for crop growth on the computer, the greenhouse environmental control system, water, and fertilizer integrated system can achieve intelligent control of the greenhouse, 2-3 people can control 2-3 million m2, which means greatly reducing labor. The daily management is mainly mechanized, and the production efficiency is significantly improved.
5 Significant social benefits
The construction of a new type of smart greenhouse can not only accelerate the structural adjustment of China's agricultural industry, increase farmers 'income, and promote the development of the agricultural industry, but also provide our residents with higher-quality, richer and safer agricultural products, and meet residents' needs for agricultural product quality, quantity, and food safety.
6 Improve economic efficiency
The first is that the yield is significantly increased, because moisture, temperature, and nutrient control are more reasonable, and the cultivation facilities are more advanced. The output of common vegetables is increased by 30% -40%, and it can also be grown out of season, and the price advantage is obvious.
The second is that the quality of fruits is significantly improved, and the color, shape, and nutrients are significantly improved. It is also possible to produce organic vegetables, scarce vegetables, precious herbs, and various famous varieties with high environmental requirements in a scientific environment.
