| 摘 要： | 以辣椒“热辣1号”为材料，采用“3414”试验设计，研究三元二次施肥模型与一元施肥模型对试验结果的拟合情况。结果表明，三元二次方程得出的推荐施肥量高于一元方程的推荐施肥量。直线加平台方程和平方根方程，Pr〉F值都没有达到显著水平，所以不能计算推荐施肥量。试验的最佳施肥量为：氮肥334．49kg/hm2，磷肥113．85kg/hm2,钾肥402．78kg/hm2。

| Abstract: | The effects of different fertilizer models (three-factor model and one-factor model)on simulation of "3414" fertilizer experiments were studied and Rela No.1 was taken as experimental material. The results showed that the fertilizer rate recommended by one-factor model simulation was lower than that recommended by three-factor model simulation in the same "3414" experiment. Because the Pr> F value of linear plus plateau and square root were not reached significant level, it can not calculate the recommended fertilizer rate. The optimum fertilizer rate was as follows: nitrogen fertilizer 334.49 kg/hm~2, phosphorus fertilizer 113.85 kg/hm~2, and potassium fertilizer 402.78 kg/hm~2. |
