【摘要】 在黑龙江省大豆生产区域性函数模型的基础上,建立了有机肥与大豆产量之间的函数模型,通过对模型的分析,求出了有机肥的增产贡献率,得出积温、降水、土壤有机质含量自然因素对农肥效应的影响,只有在化肥和有机肥适当配比的条件下,可能达到大豆的高产水平.有机肥可以替代化肥,通过研究给出了有机肥对化肥的替代率及替代条件.更多还原

【Abstract】 Based of the regional model of soybean production in Heilongjiang Province,the model between soybean yield and farmer manure is established. According to the analysis,yield contribution of manure is evaluated,we conclude that accumulated temperature,precipitation,organical matter in soil effect manure’s availability. When combinations of chemical fertilizer and manure is proper,the soybean yield can reach high level. Manure can substitute the chemical fertilizer,and the rate of substitution and the condition of substitution is given更多还原
