江西红壤丘陵地区广泛分布着一种低产水稻土,由于这种水稻土灌水耕耙后,浑水迅速澄清,表土发生严重的淀浆板结现象,故当地农民称之为沉板田(也有称之为面浆田的)。土壤学文献中一般把它归属于红壤性水稻土。据江西土壤普查资料统计,全省共有这种水田约148万亩,主要集中分布在浙赣路沿线的广大丘陵地区。我们在江西蚕桑场和万福、仙里两人民公社范围内,通过1:5000的详测制图,查出该地区沉板田面积达5653亩(尚未包括淀浆板结性质不很显著的黄板田及受花岗岩风化物影响,石英砂粒含量较高的沉砂田),占水田总面积的30%左右,是当地最主要的低产土壤。
Jiangxi red soil hilly areas are widely distributed in a low-yielding paddy soil, as a result of this paddy soil irrigation rake, the muddy water quickly clarified, the surface soil serious slurry compaction, so the local farmers called Shen plateau (also known as For the pulp field). Soil science literature generally classified it as red soil paddy soil. According to Jiangxi soil census data statistics, the province has a total of about 148 acres of paddy fields, mainly concentrated in Zhejiang and Jiangxi along the vast hilly areas. In the area of Jiangxi Silkworm Farm and Wanfu and Sinli Township People’s Communes, we found a detailed plan of 1: 5000, covering an area of 5653 mu for the Shenbantian area in the area Granite weathering, sand content higher quartz sand), accounting for about 30% of the total paddy field, is the most important low-yielding soil.
