【 摘 要 】

The experiment was carried out by planting corn on the compound soil formed by mixing different proportions of soft sandstone and sand. The distribution and migration of nitrate nitrogen and ammonium nitrogen in the compound soil were studied. The results showed that: 1.Soil nitrate nitrogen was easily leached by water, and the greater the proportion of sand in the compound soil, the faster the soil nitrate nitrogen was leached and the depth of the leaching is deeper; 2. The content of ammonium nitrogen in the compound soil was generally low, and the higher the sediment concentration of the compound soil, the greater the change of ammonium nitrogen. Therefore, appropriate measures should be taken in the compound soil with high sediment concentration to reduce the fertility waste caused by nutrient loss.
