摘要
采用二因素三水平组合为正交设计试验 ,对甘薯施肥用钾肥增产效果进行了研究。在同一种插植方式的块根产量结果中 ,产量表现为 :氮、磷、钾配合产量高于氮、钾配合肥 ,施氮、钾配合肥高于氮、磷配合肥。因此 ,在甘薯栽培上 ,应采用氮、磷。
The effect of potassium fertilizer on sweet potato yield was studied through using an orthogonal design with two factors in three levels. The result indicated that in all three plant formulas, the sequence of fertilizer effect was: NPK>NK>NP. According to the result, we recommend that in sweet potato cultivation, it is better to integrate nitrogen fertilizer with potassium and phosphorus.
