在研究资料和借鉴已有模型的基础上,本文提出一个描述冬小麦生长、水分和氮效应的简化模型,其目的是对氮肥的合理施用进行有效的预测。通过对模型的初步验证,表明田间实际测定的冬小麦经济产量和体内氮浓度与模拟值之间具有良好的一致性,在研究条件下,模型没一定的应用价值。由于资料不全,模型没有得到充分的验证,有待今后进一步的研究。
Based on the research data and the existing models, this paper presents a simplified model for describing the effects of winter wheat growth, water and nitrogen. The purpose of this paper is to predict the rational application of nitrogen fertilizers. Through the preliminary validation of the model, it shows that the actual measured winter wheat yield and in vivo nitrogen concentration have good consistency with the simulated value. Under the research conditions, the model has no certain value. Due to incomplete information, the model has not been fully verified and needs further study in the future.
