一、黄夹泥田的概况及其剖面特征黄夹泥田分布在湖南省丘陵地区,由石灰岩、页岩、第四纪红色粘土等母质发育而成.系岸田,排田,台田,地势较高,大多为丘陵中坡或坡脚,坡度为5—10°,是低产水稻土主要类型之一,分布范围很广.土壤性状,根据在祁阳黎家坪公社官山坪大队联江生产队黄家岭大脑古坵观察所得结果如下:该地为一丘陵中坡,坡度为9—10°,母质为石灰岩的风化物,剖面性状如下:
First, the overview of yellow sand mud fields and profile features Yellow sand muddy fields are distributed in hilly areas of Hunan Province, developed from the parent material of limestone, shale, Quaternary red clay and so on. Kishihito, Pai Tian, Taita, higher terrain , Mostly in the hilly slope or slope foot, slope of 5-10 °, is one of the main types of low-yield paddy soil, a wide range of distribution. Soil properties, according to Lianyuan Ping in Liyang Pingguan Liangyuan Production Team Huangjialing The results obtained from the observation of the ancient brain of the brain are as follows: The area is a hilly mid-slope with a slope of 9-10 °, and the parent material is weathering material of limestone. The profile is as follows:
