一、磺酸田的产生与受害水稻生长状况连江县浦口公社自1957年开始,即发现了小面积的磺酸田为害水稻生长.1963年全社受害面积发展到720多亩,其他敖江、灌头等公社亦有不同面积受害.近年来磺酸田经常在沿海各地发现,面积逐渐扩大,如不加以改良,必定严重影响发生地区的粮食产量.根据调查研究,我省磺酸田的产生大致有两种形式:一是自成型的,发生于沿海地区滩地水田,在水田底土层中埋有古代的红树林之类残体,由于残体内含有多量的单宁酸和含硫物质.在一般情况下,埋在深层的残体并不影响水稻生长;但是在干旱或经过深耕使红树残体翻到耕作层,经晒干氧化分解以后,便产生有毒物质和强酸反应,而成为危害水稻生长的磺
I. Production of Sulfate Field and Growth Situation of Damaged Rice The Pukou commune of Lianjiang County started to discover that a small area of sulfonic acid field damaged rice growth in 1957. The area affected by the disease in the whole society in the year of 1963 developed to 720 mu and other Aojiang, Sinkou and other communes also have different areas of victimization.Sulfonate field in recent years often found in coastal areas, the area gradually expanded, if not to be improved, will seriously affect the occurrence of food production in the region.According to the survey, the production of sulfonate field in our province roughly There are two forms: First, self-forming, occurred in the coastal paddy fields, buried in the paddy soil in the ancient mangrove debris, due to the body contains a lot of tannin and sulfur-containing substances in the general In the case, buried in the deep debris does not affect the growth of rice; but in the arid or after deep plowing mangrove turned over to the tillage layer, after the sun-dried oxidative decomposition, it will produce toxic substances and strong acid reaction, and become a hazard to rice Sulfur growing
