以科玉3号为材料，运用“3415”（三因素四水平15个处理）试验方案进行玉米肥料效应试验，通过对试验数据进行回归分析，发现玉米产量与氮、磷、钾施用量之间有显著的相关性，经三元回归分析得出每公顷氮磷钾最大施肥量为N 238.31 kg，P 110.47 kg，K 106.46 kg，最佳效益施肥量为N184.06 kg，P 83.94 kg，K 79.72 kg，而一元回归得出的每公顷氮磷钾最大施肥量为N 187.921 kg，P 80.92 kg，K 77.03kg，最佳施肥量为N 169.79 kg，P 72.72 kg，K69.82 kg。从数据来看，采用一元二次回归得出的最大和最佳施肥量更接近试验施肥方案。
以科玉3號為材料，運用“3415”（三因素四水平15箇處理）試驗方案進行玉米肥料效應試驗，通過對試驗數據進行迴歸分析，髮現玉米產量與氮、燐、鉀施用量之間有顯著的相關性，經三元迴歸分析得齣每公頃氮燐鉀最大施肥量為N 238.31 kg，P 110.47 kg，K 106.46 kg，最佳效益施肥量為N184.06 kg，P 83.94 kg，K 79.72 kg，而一元迴歸得齣的每公頃氮燐鉀最大施肥量為N 187.921 kg，P 80.92 kg，K 77.03kg，最佳施肥量為N 169.79 kg，P 72.72 kg，K69.82 kg。從數據來看，採用一元二次迴歸得齣的最大和最佳施肥量更接近試驗施肥方案。

With Yuke No.3 as material,a fertilizer effect experiment using the “3415”test scheme was carried out.The experimental data showed that there were significant correlations between yield of maize and nitrogen,phosphorus,potassi-um fertilizer.The analysis of three element regression got the largest amount of fertilizer of nitrogen,phosphorus,potassium per hectare were 238.31,110.47,106.46 kg respectively,and the best benefit amount of fertilizer was N184.06 kg,P83. 94 kg,K79.72 kg.While the analysis of one element regression got the maximum amount of fertilizer per hectare of N,P, K were 187.921,80.92,77.03 kg respectively,and the best benefit amount of fertilizer was N169.79 kg,P72.72 kg,K69. 82 kg.Viewing from the data,it concluded that the data based on one element regression analysis are more close to the ex-perimental fertilization scheme this experiment used.
