冬小麦为淮北平原的主要农作物,但其生长期刚好处于干旱期,为计算冬小麦生长期内地下水对作物根区水分的补给量,结合五道沟试验站的实测数据,在裸地潜水蒸发研究基础上提出了有作物生长条件下的潜水蒸发公式,并以2005年为例,计算浅层地下水对农作物的补给水量(即潜水蒸发量),并用水量平衡方程对该公式进行验证。 Winter wheat is the main crop in Huaibei Plain, but its growth period is just in the dry period. In order to calculate the recharge amount of groundwater to crop root zone during winter wheat growing period, based on the measured data of Wudaogou experimental station, On this basis, a formula of submersion evaporation with crop growth was proposed. Taking 2005 as an example, the amount of recharge of groundwater to the crops (ie, the amount of submersible evaporation) was calculated. The equation was verified by the water balance equation.
