冷浸烂泥田是一种主要的低产水稻土,在生产上的综合表现为水稻前期迟发坐蔸,后期贪青晚熟、病虫为害严重、籽粒不饱满,产量很低。一般亩产600～700斤,比正常田块少收稻谷300～500斤,减产60～70％。冷浸烂泥田(简称冷烂田,下同)主要分布在地势低洼、地下水位高、排水困难或有冷泉水渗入及日照少、热量不足的地方。我县经过土壤普查,基本弄清了冷烂 Cold-soaked muddy field is a major low-yielding paddy soil. Its general performance in production is delayed sedentary rice in early prophase, late greyness and late maturing, serious pests and diseases, insufficient grain and low yield. Generally 600 to 700 kg per mu, less than the normal field block rice 300 to 500 pounds, 60 to 70% reduction. Cold-soaked mud fields (referred to as cold fields, the same below) are mainly distributed in low-lying, high groundwater levels, drainage difficulties or the infiltration of cold spring water and less sunlight, lack of heat. After my county soil survey, the basic clear cold rotten
