安徽南部的沿江丘陵地带的紅壤,目前还有大面积的荒地没有开发利用,已垦的耕地也存在着大片的低产土壤,其粮食产量只有百佘斤,瘦、酸、旱、病虫为害和土壤侵蝕,是利用上存在的突出問題。同时皖南地处我国亚热带的北緣,受寒冷气候影响很大,使一些适合在紅壤上生长的經济植物受到限制。目前已經明确,这里最好是发展茶叶生产,但这幷不是說皖南的紅壤就不能种 There are still large areas of wasteland that are not exploited and used in the red soils along the hilly areas in southern Anhui Province. Large areas of low-yield soils are also found in cultivated land, with only 100% of the grain output, thin, acid, drought, pests and diseases Soil erosion, is the use of outstanding problems. At the same time, southern Anhui is located in the northern margin of China’s subtropics, affected by the cold climate is very large, so that some suitable for growth in red soil economic plants are limited. It is now clear that it is best to develop tea production here, but this does not mean that red soil in southern Anhui can not be planted
