建国以来,为配合我省的红壤垦殖利用和农业生产,进行了红壤水分的试验研究。现将1962年以来的试验研究资料整理如下。 研究方法 试验土壤系江西中北部进贤县第四纪红色粘土母质发育的低丘陵厚层红壤,包括不同熟化程度的旱地,坡度在3—5度。自然红壤剖面具有明显的三个层段:上层,疏松均质的红棕色土层;中层,紧实,核状结构的暗棕色铁锰斑淀积层,下层,深厚杂色(红、棕、黄灰)的漏管—虫状网纹层。全剖面轻粘土质地,不利土壤水分的顺利运行。开垦利用后处在不同熟化阶段的旱地红壤,第一层段可发育成2—4层(表土、二黄土、肉礁及红礁)。这类土壤面积大,有代表性。
Since the founding of the People’s Republic of China, the red soil moisture has been experimentally studied in order to cooperate with the reclamation and agricultural production of red soil in our province. The experimental research data since 1962 is now organized as follows. Research methods The test soil is a thick layer of red soil of low hills developed from the Quaternary red clay parent material in Jinxian County, central and northern Jiangxi Province, including dry land with different degrees of maturation, with a slope of 3-5 degrees. Natural red soil profiles have three distinct layers: the upper, loose homogeneous reddish brown soil; the middle, tight, nuclear structure dark brown iron manganese deposits, the lower, deep variegated (red, brown, Yellow-gray) of the leak tube - worm-shaped layer. The whole section of light clay texture, adverse soil moisture smooth operation. After reclamation and utilization, the red soil of dry land at different stages of ripening can be developed. The first layer can develop into 2-4 layers (topsoil, second loess, reef and red reef). Such soil is large and representative.
