低丘红壤垄田,通常称为山垄田,分布于低丘沟谷部位,是由红壤母貭在水耕熟化条件下发育而成的。据浙江农科院红壤改良试验站调查测算结果,这类红镶垄田在金华地区分布较多,如衢县有38万亩,金华有27万亩,其中大部为红砂泥田,一部分为黄筋泥田,少数为紫大泥田;其他地区也有少量分布,估计全省共有红壤垄田100万亩左右。低丘红壤垄田的特点是:(1)地形变化大,同一条垄内,田块之间的土貭、水利条件均有相当差异,垄顶田易干旱,垄底田易积水,垄边田土貭较轻松,垄心田土貭较粘重。这些条件的变化又都
Hilly red soil ridge fields, commonly known as mountain ridge fields, distributed in the hilly valleys, red soil is developed by marsh under hydroponic curing conditions. According to Zhejiang Academy of Agricultural Sciences Red Soil Improvement Experimental Station survey results, such a red-fitting Ridge Ridge distribution in Jinhua more, such as Qu county has 38 million mu, Jinhua has 27 million mu, most of which are red sand muddy fields, part of Yellow tendons muddy fields, a small number of Purple muddy fields; other regions also have a small amount of distribution, estimated that the province a total of 1000000 acres of red soil ridge fields. Hilly red soil ridge is characterized by: (1) large terrain changes, with the same ridge, the soil between the plots, water conditions are quite different, ridge field is easy to drought, ridge-field water, ridge Edge soil Tuo more relaxed, ridge heart Tian Tuo more sticky. These conditions change again
