Kunshan Lujia Future Smart Pastoral A+ Greenhouse is planned and constructed by AgriGarden, and it covers a total area of 45 mu. The greenhouse construction area is nearly 20,000 square meters, and eight functional areas are laid out, including a plant factory, tomato factory, cucumber factory, tomato factory, leafy vegetable factory, strawberry factory, seedling factory, and automation equipment packaging area. The latest self-developed Internet of Things system of AgriGarden- AgriLink has been introduced, which is a model of factory agriculture at an international level independently developed by China.
Among them, the seedling factory adopts automatic tidal irrigation technology beds to achieve accurate water and fertilizer supply, which can save more than 50% of water consumption, more than 75% of fertilizer consumption, and 90% of labor compared with conventional seedling factories. It realizes intelligent closed recycling and "zero discharge" of water and fertilizer coupling, which is very in line with the "green" development concept of modern agriculture.
The leafy vegetable factory adopts advanced DFT nutrient liquid pool cultivation technology, which is conducive to maintaining the stability of pH, EC value, dissolved oxygen, temperature, and other factors in the nutrient solution. The leafy vegetables produced have high neatness and good taste. In terms of automated production, the leafy vegetable factory adopts modular mechanical units to realize automatic colonization, automatic harvesting, automatic disinfection, irrigation water recycling, top heating, and other technologies, realizing the management and control of the entire Internet of Things network, and improving the operation efficiency by 20%.
The cucumber factory adopts suspended coconut bran soilless cultivation technology, and it is equipped with cucumber picking vehicles, AGV transport vehicles, and other automated horticultural production equipment, which is convenient for cultivation and operation. It also reduces labor usage and effectively improves the utilization of greenhouse space.
The strawberry factory adopts suspended coconut bran soilless cultivation technology, which effectively reduces the harm of strawberry plant diseases and insects and the rate of dead seedlings by 65%, breaking through the industry problem of the high dead seedling rate in strawberry planting.
The eight functional areas of the A+ greenhouse have formed a single variety from seed selection, seedlings, production facilities, intelligent equipment, process management, postharvest packaging, and marketing of the whole industry chain model exploration and demonstration. Based on the Yangtze River Delta urban agglomeration, the project will gradually form a full set of specifications, processes, equipment, and other systems for modern facility horticultural production management. It will become a replicable and generalizable model and serve the upgrading of facility agriculture across China.
