摘要:
土壤水分、盐分、地下水埋深是表征当地土壤质量的重要状态变量,研究其动态变化过程是研究土壤质量演变规律和赖以防治土壤盐渍化的重要方面.在农田明渠排水条件下,土壤中发生的各种物理、化学和生物过程尤为复杂.因此通过对农田土壤盐分的定点实时监测,能够定量表征农田生态环境状况优劣;地下水位埋深变化,可警示农田盐渍化的演变,对调整灌溉定额采取预防措施有指导意义.同时通过实验计算确定了农田斗排的合理间距.
Abstract:
Soil moisture,salinity,groundwater depth are the important state variable of symptom local soil quality and studying its development change course is mainly concentrated in soil quality changes and its prevention of soil salinization.In farmland drainage condition,the various physical,chemical and biological courses that occur in soil are particularly complex.Therefore,the fixed point and real time monitoring can be able to quantitative characterization of the merits of farmland ecological environment.Groundwater fluctuation can warn development of agricultural field salinization.It can help leader adjust irrigation quota and adopt preventing measures.At the same time,we find the proper interval of drainage canal based on experiment.
