红壤性水稻土是江西主要的耕作土壤。在长期肥—稻—稻种植利用下。有机肥料中的有机物质与土壤中的粘粒矿物相互作用形成有机无机复合体,对提高土壤综合肥力和土地生产力有着重要的作用。近几年来,我们对本所稻田有机肥长期定位试验,进行了土镶有机无机复合度的分析,主要探讨不同施肥措施下,有机无机复合体的变化及其对作物产量的影响,为建立合理的施肥结构提供科学依据。
Red paddy soil is the main tillage soil in Jiangxi Province. In the long-term fertilizer - rice - rice under the use of planting. The organic matter in organic fertilizers interacts with the clay minerals in the soil to form organic-inorganic complexes, which play an important role in improving soil comprehensive fertility and land productivity. In recent years, we conducted a long-term experiment on the organic fertilizers of paddy field in our institute, and analyzed the organic-inorganic compound degree of soil-borne. The main contents of organic-inorganic complex under different fertilization measures and their effects on crop yield were discussed. Fertilization structure to provide a scientific basis.
