摘要:
在分析现有的土壤水分预报方法的基础上，研究了不同深度的大田土壤水分消退指数随作物生长时间的变化规律，探讨了冬小麦生育期土壤墒情预报的经验递推方法，通过研究表明：利用土壤水分消退法来进行田间土壤水分预报，具有方法简单，所需参数较少且容易获取，预报结果可靠，精度较高的优点，可以满足灌溉预报的要求。
Abstract:
Based on analyzing the advantages and disadvantages of different kinds of soil moisture forecast methods, the soil moisture exponential depletion relations of different depths soil are analyzed, the empirical method to forecast soil moisture based on soil moisture exponential depletion relations is discussed. The results show that the method is simple with few easily acquirable parameters, reliable, and precise, it can forecast the large area field soil moisture.
