摘要

水对油棕的生长和生产力至关重要，因此充足的降雨有助于油棕对水的需求。充足的降雨对获得良好的生长和产量至关重要。据报道，在过去的23年里，马来西亚Serting Hilir灌溉棕榈树的产量响应为12吨/年，比未灌溉的棕榈树高56%。滴灌系统被选择用于灌溉水源有限但养分投入充足的地区。然而，在水源无限的地区，沟灌系统更受青睐。对油棕种植区实施灌溉的经济性进行了可行性分析。分析表明，灌溉可使产量增加5-6吨/年，在经济上是可接受的。为了灌溉油棕种植园，需要大量的水源。然而，保存渗透到土壤中的水是解决供水有限、地形不适宜和物流问题的最实际的方法。本文综述和讨论了各种可行的提高油棕产量的水土保持技术。

OIL PALM WATER REQUIREMENT AND THE NEED FOR IRRIGATION IN DRY MALAYSIAN AREAS

Water is essential for the growth and productivity of oil palm and hence adequate rainfall contributes to the oil palm water requirement. Sufficient rainfall becomes crucial in attaining good growth and yield. Over the past 23 years, the yield response from irrigated palms in Serting Hilir, Malaysia was reported to be 12 t ha –1 year –1 or 56% higher than the non-irrigated palms. The drip irrigation system is selected to irrigate areas with limited water sources but with sufficient nutrient inputs. However, in areas with unlimited water, the furrow irrigation system is favoured. Feasibility analysis on irrigation implementation economics was done for the oil palm plantation. The analysis showed that irrigation is able to increase the yield by 5-6 t ha –1 year –1 which is economically acceptable. To irrigate an oil palm plantation, a large source of water is required. Nevertheless, conserving water that penetrates the soil is the most practical approach to resolve issues of limited water supply, unsuitable terrains and logistics. The present paper reviews and discusses various techniques for soil and moisture conservation that are viable to increase oil palm yields.
