研究认为,白浆土的形成有其特殊的母质条件,白浆土母质中的粘粒易于分散,随下行水流发生机械淋溶,使上层粉砂化,下层形成深厚的粘化层。随着植物的生长,有机质的积累,粘粒的机械淋溶受到抑制,而逐步被还原淋溶和络合淋溶所取代,最终使亚表层脱色形成白浆层。白浆土在生产上的障碍因素主要是物理性质不良,由于粘化层的存在,容水量小,怕旱怕涝,调节土壤水分是改良白浆土的关健所在。对于养分问题,通过施肥,易于得到解决。试验证明,白浆层施加黄粘土改变其机械组成,表现出良好效果。
The study shows that the formation of albic soil has its own special parent material conditions. The clay particles in albacore soil are easy to disperse. With the falling water flow, mechanical leaching takes place, the upper layer is silted, and the lower layer forms a thick layer. With the growth of plants, the accumulation of organic matter and the mechanical leaching of cosmids were inhibited, and gradually replaced by reducing leaching and complexing leaching, finally, the sub-surface bleached to form a white pulp layer. Obstacles to the production of albic soil is mainly the physical properties of the poor, due to the presence of the sticky layer, the capacity of small, afraid of fear of waterlogging, regulating soil moisture is the key to improving the white soil. For nutrients, fertilization can be easily solved. Experiments show that the white clay layer to change the mechanical composition of yellow clay, showing good results.
