据目前了解,发育在湖北省第四纪红色粘土和褐色粘土沉积物上的水稻土,有相当面积的“发红”田,但各地名称不一。如在京山一带称为瘦遨疳田,江陵一带称为红斑瘘,宜都一带称为火坑田,襄阳一带称为地火田,鄂城一带称为澿水田等。从全省肥料试验网施磷的效果来看,可以肯定水稻发红是由于土壤磷素营养缺乏所引起的。 According to the present understanding, the paddy soil developed on the Quaternary red clay and brown clay sediments in Hubei Province has a considerable area of ​​“reddening” fields, but its names vary from place to place. Such as in the Jingshan area called thin amateur Tian, ​​Gangneung area called erythema fistula, Yidu area called fire pit field, Xiangyang area called the fire field, Echeng area called Sui paddy fields. Fertilizer from the province’s experimental network phosphorus effect, it is certain red rice is due to lack of soil phosphorus nutrition caused.
