摘要
【目的】为贵州稻田土壤养分进行合理的管理,进而推荐水稻种植的科学施肥,最终实现水稻种植的高产高效。【方法】运用GIS技术,采用二级分区方法,以积温、海拔、地形地貌、土壤类型以及土壤养分作为指标,对贵州稻田土壤进行养分管理分区。【结果】以地形地貌、水稻土类型分布、有效积温、海拔为分区指标将贵州稻田土壤划分为6个一级分区,在一级分区的基础上加入土壤养分指标划分9个土壤养分管理分区。【结论】通过对稻田土壤养分管理分区规划,将贵州分繁复杂的有效积温、地形地貌、土壤类型、土壤养分等进行有序的归类。
【Objective】This paper aims to rationally manage paddy soil nutrients,provide the scientific basis for rational fertilization in rice production and realize high production and high efficiency of rice production in Guizhou.【Method】The paddy soil nutrient management subarea is divided by taking accumulated temperature,elevation,topography,soil type and soil nutrient as subarea indexes and using the second-grade subarea method based on GIS technology. 【Result】The paddy soil is divided into six first-grade subareas according to the subarea indexes of topography,paddy soil type,effective accumulated temperature and elevation and nine soil nutrient management subareas are divided according to soil nutrient indexes based on the first-grade subarea results in Guizhou. 【Conclusion】The complex effective accumulated temperature,topography,soil type and soil nutrient are orderly classified by planning management subarea of paddy soil nutrients in Guizhou.
