3 Requirements
3.1 Basic Requirements
3.1.1 The organic tea production area should have good water quality, high biodiversity index, far away from pollution sources and strong sustainable production capacity. The distance between the organic tea garden and the traffic artery should be more than 1000m. 3.1.2 There should be a clear boundary and isolation zone between the organic tea garden and the conventional agricultural production area to ensure that the organic tea garden is not polluted. The isolation zone should be a natural barrier such as mountains and natural vegetation, or it can be artificially created forests and crops. Crops should be cultivated according to organic agricultural production methods.
