| 摘 要： | 在黑龙江省玉米生产区域性函数模型的基础上, 建立了农肥与玉米产量之间的函数模型,通过对模型的分析, 得出积温、降水、土壤有机质含量对有机肥效应的影响, 只有在化肥和有机肥适当配比的条件下, 可达到玉米的高产。有机肥和化肥可以互相替代, 本文给出了有机肥和化肥的替代率及替代条件。

| Abstract: | Based of the regional model of maize production in Heilongjiang Province, the model between maize yield and farmer manure is established. According to the analysis, we conclude that accumulated temperature, precipitation, organical matter in soil effect manure′s availability. When combinations of chemical fertilizer and manure is proper, the maize yield can reach high level. Manure can substitute the chemical fertilizer, and the rate of substitution and the condition of substitution is given.$$$$ |
