冷浸田是长期浸水形成的一种强还原性的低产水稻土,广泛分布我国南方各省山地、丘陵和冲积平原的低洼地。根据水分状况和理化性质的不同,冷浸田可分为烂泥田、冷水田和锈水田三种类型,其中以烂泥田面积最大,其他两种多是由烂泥田发展而成,有的呈复区分布。我省地跨南、中亚热带,年平均温度为18~20℃,年雨量1200~2000毫米,是一个高温多雨地区,红壤山地、丘陵占土地总面积80%以上。冷浸田分布相当广泛,全省约有150多万亩,占水稻土总面积10%以上。
Cold soaked fields are a kind of strong reducing low-yielding paddy soils formed by long-term water immersion. They are widely distributed in the lowlands in the mountains, hills and alluvial plains in the southern provinces of our country. According to the different water conditions and physical and chemical properties, the cold-immersed fields can be divided into three types: muddy field, cold paddy field and rusty paddy field, of which the area of the muddy field is the largest, the other two are mostly developed from the muddy field, District distribution. The province’s southern and central subtropics, the annual average temperature of 18 ~ 20 ℃, annual rainfall of 1200 to 2000 mm, is a hot and rainy areas, red soil mountain, hills account for more than 80% of the total land area. Cold paddy field is widely distributed, the province about 150 million mu, accounting for more than 10% of the total area of paddy soil.
