摘要
根据河西绿洲灌区春小麦全生育期(3—7月)的水文、气象、作物生长等资料,采用彭曼法PenmanMethod的ET0i值预报模型,运用多元线性回归进行参考作物的腾发量预测,以及其它参数模型及公式的确定,建立了河西绿洲灌区春小麦精确灌溉预报参数模型。
According to the experimental area of spring wheat throughout the growth period of three to sever months of hydrological, meteorological, crop growth, etc., using penman method of ET0i value prediction model by using multiple linear regression of reference crop evapotranspiration forecasts, and other parameters of model and formulas to determine. Finally, parameter model of the precise irrigation forecast of spring wheat in Hexi oasis irrigated was established.
