本文从土壤矿物组成,碳、氮、磷营养水平及其在各位级复合体中的分配等方面比较了黄褐土和潮上的供肥性能。结果表明,黄褐土以粘粒级复合体为主,潮土则以砂粒级复合体为主,另外两者粘土矿物有别,粘粒复合体碳、氮和磷分配不同。相比之下,黄褐土保肥能力较好,而潮土的供肥能力较强。轮作柽麻5年,可改善土壤磷素营养并更新土壤有机质。
In this paper, the fertility of the yellow cinnamon soil and the tide was compared in terms of soil mineral composition, carbon, nitrogen and phosphorus nutrient levels and their distribution in each level complex. The results show that the yellow cinnamon soil is dominated by the clay-type complex, the sand-soil layer is dominated by the sand-grained soil, and the other two are different in clay minerals. The distribution of carbon, nitrogen and phosphorus in the clay-particle complex is different. In contrast, yellow cinnamon better fertilizer retention capacity, while the supply of strong soil moisture. Crop rotation for 5 years, can improve soil phosphorus nutrition and update soil organic matter.
