Lettuce is both delicious and nutritious, and is often used to cook various delicious dishes in daily life. Greenhouse cultivation of lettuce is no longer a new thing, but have you ever seen the planting mode of hydroponic lettuce in a greenhouse?
Soilless cultivation of vegetables is a modern agricultural technology with high technological content and high yield. The products produced by soilless cultivation technology have the advantages of high yield, and anti seasonal production by using protective facilities such as greenhouse to control environmental conditions. If these vegetables, melons and fruits are marketed, better economic benefits can be achieved. NFT greenhouse planting vegetables is another innovation in the soilless cultivation mode. It combines greenhouse and NFT three-dimensional cultivation mode, which can achieve higher achievements in vegetable planting. This is a modern intelligent greenhouse.
There are many types of NFT hydroponic planting systems, among which A-type NFT is often used in greenhouses. It adopts an A-shaped layout structure, with a beautiful appearance and convenient fixed value management, making it one of the representative modern soilless cultivation models that is both beautiful and practical. The A-type NFT hydroponic culture is more suitable for planting leafy vegetables and fruit crops with low plants and short roots, so it is very suitable for lettuce cultivation.
Advantages of a vertical NFT greenhouse system:
1. Save land resources. The land occupation area is small, and the land utilization rate is as high as 3-4 times or more.
2. Improve production and quality. The NFT planting model has a high yield, increasing it by 10% compared to traditional greenhouses under the same conditions.
3. Green and pollution-free. Modern intelligent greenhouses have automatic control functions of constant temperature and humidity, which can reduce the occurrence of diseases and pests in greenhouses; Without the occurrence of pests and diseases, the use of pesticides to pollute crops and the environment can be avoided, which is truly green and pollution-free.
4. Reduce investment in costs. On a certain scale, reduce infrastructure investment, mobilize the enthusiasm of management and production employees, reduce production costs, and facilitate management operations and labor protection.
Lettuce is not resistant to high temperatures and is suitable for growing in cool climates. The most suitable temperature is 15-20 ℃. Under low temperature conditions, lettuce has high yield and excellent quality. When the temperature exceeds 30 ℃ for a long time, there will be growth barriers, which are prone to bolting and flowering, seriously affecting yield, quality, and economic benefits. Hydroponic lettuce has developed into one of the mainstream lettuce cultivation methods due to its advantages of improving crop yield and quality, reducing labor, saving water and fertilizer, continuous annual production, and safety and hygiene.
NFT system is a soilless cultivation method that plants crops in shallow flowing nutrient solution, which can be recycled. In recent decades, it has emerged globally, and many greenhouses have joined the army of hydroponic cultivation. Establishing a hydroponic greenhouse requires a certain level of technical expertise, and it is also reminded that those who want to develop NFT hydroponic greenhouses should first understand and then make further attempts.
