摘要
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．
A mathematical model of natural productivity of wheat was established through the location experiments of ecological net and was used to research comprehensively the effect of three ecological factors,heat,water and soil fertility,on the dynamic of natural productivity of wheat.The natural productivity of wheat in the areas with different climate conditions and fertility levels in Heilongjiang province was predicted.
