China Professional Low Cost Agricultural Greenhouse Tunnel
However, some people question the safety of greenhouse vegetables, so the editor clearly tells everyone that greenhouses only provide a relatively suitable growth environment for crops. As for the problem of excessive fertilizer and pesticide residues, it belongs to the category of planting and cultivation. It can also occur in ordinary field cultivation. However, as the country controls pesticides, eliminates highly toxic pesticides from the source, and promotes the development of low-toxic, fungus, and biological control technologies, the safety of crops has been greatly improved. At the same time, the promotion and creation of more and more pollution-free and green brands has also played a great role in promoting ecological planting.
1. The purpose of planting
The upgraded greenhouse can grow vegetables, cultivate seedlings throughout the year, plant valuable Chinese herbal medicines, and in short, high-end flowers for scientific research and breeding. At the same time, it can grow hydroponic vegetables, substrate-grown vegetables and other modern planting combined modes. Not only increase production, but also improve the quality of agricultural products.
Because the intelligent greenhouse provides a large space, transparent building, and can control shading, ventilation, and cooling, the indoor environment can reach an environment suitable for plant growth and visitors' experience. At the same time, compared with the traditional steel structure exhibition hall, the cost is more economical, the construction speed is faster, the hot-dip galvanized structure has better anti-corrosion performance, and the service life is longer.
Therefore, in recent years, it has been widely used in tropical rainforest botanical museums, leisure ecological gardens, leisure picking gardens, high-quality specialty agricultural products exhibition halls, ecological restaurants, agricultural carnival greenhouses, private leisure gardens, specialty organic vegetable gardens, etc.
3. Precautions for the construction and use of the upgraded greenhouse
Due to the problem of large sheds from the previous year, some landscape greenhouses and eco-restaurant greenhouses engaged in leisure agriculture and tourism in characteristic towns have been hit hard. Therefore, when we build new greenhouses, we must conform to the nature of the local facility agricultural land. , Do not occupy basic farmland. After the incident, the Ministry of Agriculture and Rural Affairs also made it clear that the multi-span greenhouses belong to the category of facility agriculture, and general facility agricultural land can be used without the need to balance the occupation and compensation. This is also affirmation and righteousness of facility agriculture greenhouses and avoids the expansion of one size fits all.
