| 摘 要： | 本文以苹果为试材,采用不同的N,P,K肥配比试验,介绍了不同肥料配比对苹果产量影响研究的方法和模式,建立了产量与肥料配比之间的关系方程: Y=AN~(b1)P~(b2)K~(b3)。对方程求导确定出其它条件不变的情况下N,P,K肥对产量形成的作用。同时建立了实施计算和比较分析的BASIC程序,并附实例进行分析。

| Abstract: | In this paper,the effect of N, P_2O_5, K_2O ferterlizers on the apple production was
investigated while the method and study about the differential compastion of N,P_2O_5, K_2O
fertilizers were introduced.Model of apple production to N,P_2O_5,K_2O is Y=AN~(b1)P~(b2)K~(b3).
From this model the contribution of N,P_2O_5, K_2O to apple production were analysied by
the BASIC programme at the PC-386 computer. |
