通过在湖北省几种主要成土母质上对不同水型水稻土施用氮磷肥效果及施用技术的研究.初步明确了氮肥的施用效果为淹育型水稻土>潴育型水稻土>潜育型水稻土.磷肥效果与之相反.从土壤养分状况、氮肥和磷肥的当季利用率、土壤微生物、土壤还原性物质含量和水土温度等方面,初步分析了不同水型水稻土氮磷肥效果差异的原因.提出了不同水型水稻土氮磷肥的施用技术.
Effects and Application Techniques of Applying Nitrogenous and Phosphorus Fertilizers on Different Types of Paddy Soils Based on Several Main Soil-forming Parent Materials in Hubei Province. It was initially clarified that the application effect of nitrogenous fertilizer was submerged paddy soil> reed paddy soil> silage paddy soil. The opposite effect of phosphate fertilizer. The reasons for the differences of nitrogen and phosphorus fertilization in paddy soils under different water regimes were analyzed based on the status of soil nutrients, seasonal utilization of nitrogen and phosphate fertilizers, soil microbes, soil reducing substances and water and soil temperature. Proposed different types of paddy soil nitrogen and phosphorus fertilizer application technology.
