通过生态网定位试验建立的小麦自然生产力数学模型，综合研究了热量、水分和土壤有机质３个生态因子对小麦自然生产力变化动态的影响．应用模型对黑龙江省不同气候、土壤肥力地区的小麦自然生产力进行了预测．
Based on the mathematical model of wheat natural productivity established by the eco-net experiment, the effects of three ecological factors of heat, moisture and soil organic matter on the dynamic changes of natural productivity of wheat were comprehensively studied. The model was applied to predict the natural productivity of wheat in different climate and soil fertility regions in Heilongjiang Province.
