| 摘 要： | 为探求油棕园适宜的灌水施肥技术,本试验采用L8（4×24）混合型正交试验,研究7龄油棕不同配比供水量和施肥水平对油棕叶片数量与全氮、全磷、全钾含量的影响。结果表明：水肥调控能有效促进油棕对矿质营养元素的吸收,灌溉比施肥更能增加油棕叶片数量;旱季油棕园适合的经济灌水量为1750L/株·周;施肥时间最好在3、7、10、12月,但7月应提高钾肥施用量。 |

| Abstract: | Experiments were made on the effect of different irrigations and fertilizer applications on oil palm leaves production,total nitrogen,total phosphorus and total potassium contents through mixed orthogonal test L8（4×24） to study optimum irrigating and fertilizing.The results showed that regulation and control of water and fertilizer could significantly promote mineral absorption by the oil palm.And compared with fertilizer,the irrigation increased more leaf production.The optimal economical irrigation was 1 750 mm/palm·week in dry season.The fertilizing time was more reasonable in March,July,October and December.However,increasing potassium content was necessary in July. |
