高、低产田土壤物理性质研究

摘要

土壤是农作物生长发育的基础条件,作物能否获得稳产高产,土壤肥力是关键因素.为此,以山西省晋城市为例,通过对黄土山丘区典型高、低产田土壤的物理性质进行分析,探讨土壤基本物理性质与农作物产量之间的关系,进而为晋城市高产农田土壤培肥、低产农田土壤改良提出相关建议,以期对晋城市下一步的农业增产及可持续发展提供借鉴.%Soil is the basic condition for crop growth and development,and soil fertility is the key factor to obtain high and stable yield.Therefore,taking Jincheng city,Shanxi province as a case,the physical properties of the soil in the typical high and low yield fields of the Loess hills were analyzed to explore the relationship between the basic physical properties of soil and crop yield,and put forward some suggestions for soil fertility improvement of high yield farmland and soil improvement of low yield farmland in Jincheng city,thus,providing a view to the next step on crop yield increasing and sustainable development in Jincheng.
