为了明确开放式空气CO2浓度增高(FACE)对水稻茎蘖消长的影响,借助目前我国惟一的FACE技术平台,通过不同的N肥处理,对FACE条件下水稻茎蘖消长的动态进行了模拟研究并建立了相应的模型。该模型由茎蘖增长动态和茎蘖消亡动态两部分组成,以时间为驱动因子,描述了水稻茎蘖数随移栽后天数的动态变化过程,对常规及CO2浓度增加条件下水稻茎蘖的变化均有很好的拟合性。通过相关试验数据对模型的检验,结果表明模型的拟合程度高,具有很好的适用性。
In order to clarify the effect of open air CO2 enrichment (FACE) on the tillering and tillering of rice, the dynamics of rice tillering and tillering growth under FACE conditions were simulated and studied by means of FACE technology platform, Established the corresponding model. The model consisted of stem-tiller growth dynamics and stem-tiller dynamics. Using time as the driving factor, the dynamic process of tillering number of rice with the days after transplanting was described. The effects of conventional and elevated CO2 concentration on tillering of rice Changes have a good fit. Through the test data of the relevant test model, the results show that the model has a high degree of fitting, has good applicability.
