结合沧州市实际情况，以冬小麦和夏玉米为典型作物分析沧州市土壤墒情变化特点，揭示沧州区域土壤墒情变化规律和演变趋势；对捷地旱情试验站土壤墒情监测资料进行分析研究，利用P要籽0要驻籽增墒相关法建立增墒预报方案，利用退墒系数法以及籽t要T要籽0相关法建立退墒预报方案，探讨适合沧州区域的土壤墒情预报方法，对类似地区相关研究具有重要的推广价值。
結閤滄州市實際情況，以鼕小麥和夏玉米為典型作物分析滄州市土壤墑情變化特點，揭示滄州區域土壤墑情變化規律和縯變趨勢；對捷地旱情試驗站土壤墑情鑑測資料進行分析研究，利用P要籽0要駐籽增墑相關法建立增墑預報方案，利用退墑繫數法以及籽t要T要籽0相關法建立退墑預報方案，探討適閤滄州區域的土壤墑情預報方法，對類似地區相關研究具有重要的推廣價值。
