摘要
为了便于施肥指导,进一步规范肥料的科学施用,对贵州省内不同海拔区域,依据地形地貌、气候条件、土壤类型、土壤养分等因素的空间变异性研究,把省内耕地划分成三级施肥分区。以土壤类型、年均温、≥10℃积温等主导因素为主要划分依据,确定了3个一级分区;在此基础上,以地貌类型、土壤类型和农业生产水平的相对一致性为主要划分依据,确定了11个二级分区;以土壤养分含量的差异与特征划分三级分区施肥单元。
The arable land in Guizhou province is divided into three classes of application divisions according to the space variability of topography, topographical features, climatic condition, soil type and soil nutrition factors. First, three first-class divisions are determined by the main division basis of soil type, annual mean temperature and accumulation temperature above 10℃. Then eleven second-class brunch divisions are determined by the main division basis of topographical features, soil type and relative identical agricultural production level. Finally, the application units with the third division are divided according to the variation and characteristic of soil nutrition content.
