plateau equation
解釋
平穩方程-
The empirical equation w = asb was used to fit water holding capacity of four kinds of agricultural soils in loess plateau. soil water holding capacity and unavailable water content increased as soil texture became clayed. available water content in loam was higher than those in sandy soil and clayed soil
黃土高原四種主要農業土壤的水分特徵曲線並無明顯的平臺或拐點產生，其關系能夠很好地用garden經驗方程（ w = as ~ （ - b ） ）進行擬合。 -
The regression equation between base moisture of soil and yield is set up, in which the soil base moisture of previous year is used as a limited factor on the yield of later year, which can forecast a upper limit of the yield with 95 % statistical significance, so the opportunity which appears when the yield determined by user disagrees to the reality, and the degree that fertilizer recommend result tallies reality is improved. the databank of model between yield under fertilizer effect on loess plateau are established, so the system estimate ability is enhanced
系統採用前一年的底墑作為后一年產量的限制因子，建立了底墑與產量的回歸方程，利用統計規律保證利用此方程對產量上限的預測達到95的置信度，以此減少用戶定產時出現不符合事實的機會，提高了施肥推薦與實際生產符合的程度；建立了黃土高原區產量效應模型數據庫，增強了系統的預測能力；採用了兩種肥料分配方案，便於不同的生產者進行選擇。
