| 摘 要： | 灰棕紫泥水稻土是四川盆地的主要水稻土，在川东地区占有较大面积。目前，针对该土壤的研究资料较少，为了更好地指导该土壤的平衡配方施肥工作，本文采用三元二次通用旋转设计对该种水稻土的不同施肥水平与油菜产量及经济效益的关系进行了研究，获得了该土壤油菜施肥与产量的数学模型。结果表明，在灰棕紫泥水稻土种植油菜，N、P一次项和NP的交互项均达到了极显著水平，K的一次项达到了显著水平。根据本试验，提出类似地区油菜高产高效配方施肥建议方案为：每公顷施用有机肥15000kg，纯N 290．25～323．25kg，P2O5 110．64～146．28k，K2O 66．90kg。

| Abstract: | The gray-brown-purple paddy soil is a main soil in Sichuan basin, accounting for the most of areas in the eastern region of Sichuan. To guide the equal application of formulation fertilizer in soil, the effects of fertilizer application levels on rapeseed yield and benefit were analyzed using the multiple-quadratic revolve test. The results showed that the test levels in the single terms of N, P and the cross term NP were significant, and in the single term of K was also significant,Based on the above results, a mathematics model of fertilizer application levd and rapeseed yield was established. Finally, the amount of fertilizer application for rapeseed in this type soil was proposed. |
