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。
Based on the regional function model of corn production in Heilongjiang Province, a functional model was established between agricultural and fertilizer production and corn yield. Through the analysis of the model, the effect of accumulated temperature, precipitation and soil organic matter content on organic fertilizer effect was obtained. Proper proportion of organic fertilizer and under the conditions to achieve high yield of corn. Organic fertilizers and fertilizers can replace each other, this article gives the replacement rate of organic fertilizer and fertilizer and alternative conditions.
