一、红壤的巨变我省丘陵红壤面积很大,分布极广,在这些丘陵之间,还有占水田总面积很大比例的红壤性水稻土.由于肥力低,水源缺,酸性重,易板结,加之反动派长期统治和破坏,大都荒芜不毛,部分水土流失严重;沟谷的水稻亩产也只二百斤上下,是我省主要低产地区. First, the huge changes in red soil Hilly red soil in our province a large area, widely distributed in these hills, there are a large proportion of the total paddy field of red soil paddy soil due to low fertility, lack of water, acid heavy, easy to knot In addition, since the reactionaries have long ruled and destroyed most of the area, they are desolate and barren, with some serious soil and water loss. Only about two hundred jin of rice per mu are produced in the valleys, making them the major low-yielding areas in our province.
