(1) The origin of organic tea should be far away from urban industrial areas, towns, residents' living areas and traffic trunks. Soil and water conservation should be good. There are lush forests around the organic tea plantations, good biodiversity, and away from pollution sources and have strong sustainable production capacity. There are no obvious and potential sources of pollution near the base, upwind outlets, and upper reaches of the river to ensure no pollution.
(2) There should be a clear isolation zone between the organic tea plantation and the conventional agricultural production area to ensure that the tea plantation is not contaminated. Natural barriers, such as mountains and natural vegetation, are suitable for the isolation zone, as well as artificially created forests and crops. Crops should be cultivated according to the mode of organic agricultural production.
(3) Tea garden soil environmental quality should meet the stipulated requirements, physical and chemical traits are better, and potential fertility levels are higher, preferably loam, oil sand, etc. The tea garden has not applied chemical fertilizers and pesticides for the past three years. The air in the production base is fresh, rich in biological vegetation, and there is a rich source of organic fertilizer around.
(4) Producers and operators of tea bases have a good production technology base. Large-scale bases have sufficient labor resources and clean water sources around them.
(5) Tea gardens should be properly concentrated, have a certain area, and be planted in a standardized manner. Tea trees have good tree vigor and fewer pests and diseases.
