新疆米泉地区起源于原灰漠土或灌耕土的水稻土，成土过程中水耕熟化和灌淤、淋溶与淀积并行，形成独特的灌淤－水耕表层（耕作层＋犁底层）和灌淤－水耕氧化还原层，总厚度＞５０ｃｍ．基于研究，将供试土壤划分为铁聚水耕人为土和铁渗水耕人为土两个土类，并建议在水耕人为土系统分类中增设灌淤亚类。 The Miquan area in Xinjiang originated from paddy soil of original gray desert soil or irrigated soil. During the process of soil formation, the soil was matured and drenched, leached and deposited in parallel, forming a unique silt-hydrophytic surface layer (tillage layer and plow bottom layer) And filling silt - hydroponics redox layer, the total thickness> 50cm. Based on the research, the test soil was divided into two groups of iron polyculture artificial soil and iron seepage water tillage manure soil. It is suggested that additional silt filling subclasses should be added to the system classification of hydroponic artificial soil.
