摘　　要：土壤墒情与旱情监测工作是抗旱减灾和旱作节水农业技术推广的基础。通过对吉林省镇赉县不同深度及不同监测地点的土壤墒情温度进行监测与分析,结果表明,镇赉县各时期平均含水量在6.3%～18.8%,全年普遍较旱,土壤含水量均在15%以下;春季土壤温度上升较快,但期间有较大幅度波动,平均土温差距较为明显。为镇赉县土壤墒情合理优化提供科学依据。Soil moisture and drought is the foundation of drought mitigation and monitoring and water-saving technology extension.Based on the monitoring and analysis of soil moisture and temperature of different depths and sites in Zhenlai County,the results showed that the average water content was 6.3%～18.8% at different stages,it was drought generally the whole year,the soil water content was below 15%.Soil temperature raised fast in spring,and it flutuated drastically,and there was obvious difference.The reasonable scientific basis was provided for soil tilth optimization.
