馬肝土的稻田(即瀦育性水稻土),分布于江淮之間和沿江南岸低山、丘陵区的塝田和上冲田,平岗区的岗坡田(岗板田),以及湖泊区的环湖高坡田。这种稻田大多是由下蜀系黄棕壤或黄褐土及它們的冲积——洪积物发育而成的,部份是由紅粘土、紫色土发育而成的。根据土壤熟化度和生产水平,一般分高肥馬肝田(如烏馬肝田)、中肥馬肝田(如黄馬肝田)、低肥馬肝田(如死馬肝田)等三种类型。由于土壤肥力、水源条件、栽培习慣、經济区划的不同,对于馬肝稻田的利用一般以中稻—小麦(或油菜)、早稻—晚稻—休閑、中稻—綠肥、中稻—豆类(蚕、豌豆)輪种为主。除高肥馬肝田外,一般中肥、低肥、低中过渡肥馬肝田的土壤体內部土罸持亍⑴帕薪裘堋⒂谢嗜狈?带来难耕、难耙、土 Paddy field (ie, paddy paddy soil) of Magan soil is distributed in Jianghuai and between Wada and Shangtiantian in the low hills and hilly areas along the southern bank of the Yangtze River and Gangbiantian (Kongtian) in Pinggang District and the lake area The high lake in the lake. Most of these paddy fields are developed from the yellowish brown or yellow cinnamon soil of the Shu area and their alluvial-alluvial deposits, partly from the development of red clay and purple soil. According to the degree of soil maturity and production levels, generally divided into high fat horse liver field (such as Wu Ma liver field), fertilizer Ma liver field (such as yellow horse liver field), low fat liver field (such as dead horse liver field) Kind of type Due to the differences of soil fertility, water source conditions, planting habits and economic zoning, the utilization of magan paddy fields is generally dominated by middle-aged rice - wheat (or rape), early rice - late rice - casual, middle rice - green manure, ) Rotate the main. In addition to high fat horse liver field, the general fertilizer, low fat, low medium transitional soil in the body of Ma liver disease to be held ⑴ Pa pay Qiu 堋 ⒂ Xie  embarrassment, difficult to harrow, harrow, soil
