田间土壤水分蒸散模型研究

Research on the Model of Soil Water Evaporation on Field

不同播期谷子田间试验表明,土壤储水量及土壤有效储水量均与作物生物量及土壤初始有效含水量有关,并建立了土壤储水量及土壤有效储水量与作物生物量及土壤初始有效含水量关系的数学模型;此外在考虑能量因子的情况下,建立了土壤储水量及土壤有效储水量与作物生物量、土壤初始有效含水量及温度关系的数学模型。

It is found that the water content and applicable water content were all relative to the dry biomass of crop and the initial applicable water content after the field trial with varied treatments, and the models on relation of water content (or applicable water content) to dry biomass of crop and the initial applicable water content were founded. When taking account of the factor of energy, the models on relation of water content (or applicable water content) to dry biomass of crop, the initial applicable water content and temperature were founded.
