    摘要:

    以華北地區(qū)冬小麥為研究對象，將AquaCrop作物生長模型應用到滴灌,、噴灌,、漫灌中，對模型主要參數如氣象,、土壤,、作物特性等進行調整,，并對作物產量和生物量模擬的有效方法進行了研究,。模擬結果表明，產量和收獲時地上部分生物量的模擬值與實測值較為接近且略高于實測值,，模型性能指數均高于0.95,。產量模擬效果優(yōu)于生物量，滴灌模擬效果最好,。

    Abstract:

    Using the winter wheat in North China as research object, AquaCrop model was applied in different technology of irrigation, included drip irrigation, sprinkler irrigation and furrow irrigation. The main parameters like soil and crop characteristics and so on, were adjusted. In addition, the effective simulation method for crop yield and biomass was researched. The study showed that some simulated values like yield and biomass of soil were significative. The relative error (RE) was low. Simulated data was a little higher than the observed one. All of the modeling efficiency (EF) was more than 0.95. The modeling was better for yield than that for biomass. The modeling was also the most efficient for drip irrigation in the three kind of irrigation technology.
