Glass greenhouse is a kind of agricultural vegetable greenhouse covered by glass, which is the final product of traditional vegetable greenhouse cultivation and upgrading. What is the biggest advantage of a glass greenhouse? What is the investment cost of planting an acre of glass greenhouse?
1. Traditional vegetable planting model
Traditional vegetable planting management models include open field cultivation, cold shed and rain shed cultivation, spring and autumn shed cultivation, and warm shed cultivation. The traditional vegetable planting model needs to undergo so many years of development, whether in terms of product quality, yield, and green pollution-free research in my country, it has reached the bottleneck of social development. Facing the emergence of more and more agricultural product network safety education problems, the main problem of white garbage pollution, and the difficulty of recultivating the soil after repeated cropping. So for us, as a reference to the development of the historical process of the vegetable industry in developed countries, as well as the concept and teaching mode, the final development level direction is the glass greenhouse.
2. Introduction to Glass Greenhouse
The glass greenhouse is a fully transparent building with a hot-dip galvanized light steel structure as the main body. The top and surroundings are covered with fixed glass of aluminum profile.
Three, the advantages of glass greenhouse cultivation
Long service life
The greenhouse is covered with hot-dip galvanized framework materials and glass, with a service life of more than 20 years, eliminating the white pollution problem of plastic film from the source.
High level of mechanization
All shading, ventilation, heating and cooling systems of the glass greenhouse are mechanized. The ventilation switch of a few acres of vegetable greenhouses can only be located on the operating line next to the distribution box, which is far from being done by traditional manual greenhouses.
Precise water and fertilizer technology
Integrated water and fertilizer cultivation is currently the most energy-efficient and accurate planting mode in the planting industry, which can eliminate soil-borne diseases and greatly save water and fertilizer. At the same time, European and American water and fertilizer recycling legislation reduces the possibility of groundwater pollution.
The popularization of IoT technology
Greenhouse planting in developed countries in Europe and the United States does not rely solely on social experience for planting, but we completely rely on information and data operations. The environmental quality control system is more accurate.
4. Investment in glass greenhouse planting
The investment cost of glass greenhouse cultivation is currently the highest in facility agriculture, generally including civil construction, greenhouse construction and internal planting. Ordinary civil construction is 30-40 yuan per square meter, and the glass greenhouse is about 300 yuan/square meter. The internal planting is calculated separately. If the building area of the unit is too small or particularly remote, the cost will increase accordingly. Regarding the return on investment in glass greenhouse planting, the current vegetable prices are indeed relatively slow. We can rely on the state’s support policy for facility agriculture and the preferential policies for poverty alleviation in the development of various parks to develop glass greenhouse planting in my country.
Glass greenhouses can not only be directly used for vegetable and flower planting in China, but also can be used as a nursery shed for greenhouse planting and production bases. At the same time, the company can also be used as an exhibition greenhouse, high-tech product display greenhouse, carnival greenhouse, vegetable and flower cultural landscape Design greenhouses, tropical rainforest botanical gardens, etc.
The development prospect of glass greenhouse
With the continuous development of society and the increase in labor costs, mechanized greenhouses are imperative. At the same time, with the adjustment of the energy structure and the reduction of energy prices, the glass greenhouse will surely usher in the climax of development after the heating cost of the glass greenhouse is reduced. Glass greenhouses will gradually replace the old film greenhouses, and the clustering and regionalization of commercial industries is becoming more and more obvious.
