AT designs low-cost, high-yield and flexibly variable-size small tunnel for farmers. They don’t need to bend over when working, and the plastic film will not be easily damaged and can be reused to reduce environmental pollution. In addition, AT will combine the effects of greenhouse planting to increase planting space through the combination of scaffolding, reducing the time and physical strength of farmers to continuously replace small tunnel. Therefore, more diverse fruits and vegetables can be planted to increase sales and reconcile soil pH, and move towards sustainable management.
