河北省平原区土壤墒情预报研究

Hebei Plain Soil Moisture Content Prediction Research

以冬小麦和夏玉米为典型作物分析了河北省平原区土壤墒情变化特点,研究3个旱情试验站土壤墒情变化规律,结合我省实际情况进行了分区研究,创建了代表山前平原区、中部平原区、滨海平原区的区域土壤墒情模型和高精度区域预报方案,揭示了河北省平原区土壤墒情变化规律和演变趋势,对类似地区相关研究具有重要的推广价值。

This study as winter wheat and summer corn as typical crop to analyze the soil moisture content change characteristic in Hebei plain, studying the three drought test station soil moisture content change rule, and regionalization research combining with the actual situation, founded the soil moisture content model and high precision area forecast scheme on piedmont plain, the central plain, and coastal plain area, this paper reveals the Hebei plain soil moisture content change rules and evolution trend, for similar areas related research has the important value of popularization.
