在格鲁吉亚的主要产茶区之一阿扎里的茶场里茶叶收获量不断地上升着。1940年鲜叶的平均收获量是每公顷3,351公斤,到1957年为4,306公斤。许多集体农庄和国营农场每公顷的鲜叶产量高达5000至6000公斤。在茶场里充分施用矿物质肥料、有机肥料和绿肥,这是阿扎里的种茶者用来保证收获量增加的方法之一。最适用于茶树栽培的是有机肥料。它们能使土壤变为更易渗透,并增进土壤的蓄水力、结构和通气性。再者,有机质还是使阿扎里土壤(灰化红壤和红壤)中大量存在的铁和铝的氧化物变为不可溶 Tea harvests continue to rise in tea plantations in Azaria, one of Georgia’s major tea producing areas. The average harvest of fresh leaves in 1940 was 3,351 kg per hectare and by 1957 4,306 kg. Many collective farms and state farms produce up to 5,000 to 6,000 kilograms of fresh leaves per hectare. The full application of mineral fertilizers, organic fertilizers and green manures in the tea plantation is one of the ways Azazar’s tea growers have been able to ensure increased yields. The most suitable for tea cultivation is organic fertilizer. They make the soil more permeable and improve soil water retention, structure and aeration. Furthermore, organic matter also renders the oxides of iron and aluminum, which are abundant in Azaria soil (ashed red soil and red soil), insoluble
