问题示例: A maize field has a net radiation of 9.6 MJ m⁻² day⁻¹, an upward sensible-heat flux of 2.4 MJ m⁻² day⁻¹, and a downward soil-heat flux of 0.6 MJ m⁻² day⁻¹. If the surface energy balance is simplified as Rn = H + LE + G, what is the latent-heat flux? 5.4 MJ m⁻² day⁻¹, 6.0 MJ m⁻² day⁻¹, 6.6 MJ m⁻² day⁻¹, 8.4 MJ m⁻² day⁻¹
