摘要
根据１９９６年有关水稻合理施肥研究的结果，于１９９７年选择６个氮磷施肥点，采用随机区组设计证实了等产量线的客观存在性及在一定范围内存在的氮磷肥相互可替代性，并用产量构成因素的变化来对此进行了初步探讨．氮磷等产量线及氮磷可替代性的客观存在。
According to the result gained in 1996 about reasonable feritilizing rate, 6 fertilizing points were choosen in1997. N,P equal-yield line and replacability were verified in terms of randomized block design, analyzed with yield factors. The existance of N,P equal-yield line and replacability provided liable principles for reasonable fertilizing and pest control
