摘 要 ： 通过在徐闻县对当地普遍种植的巴厘种菠萝展开不同管理方式的对比研究，探讨了滴灌施肥与常规施肥对菠萝产量、 品质以及经济效益的影响。试验设3个处理， 空白对照、 常规施肥和滴灌施肥。结果表明，与常规施肥相比，在菠萝上使用滴灌施肥技术，产量可达到81405 kg/hm²，增产39.04%，果实内在品质无下降，但商品品质得到大幅度提高，商品果率为95.73%，较常规处理高11.51%。净收入较常规施肥处理高69670 Yuan/hm² ，增长92.07%，节省用工成本1125 Yuan/hm²，产出投入比由2.00∶1上升到2.97∶1。N、 P₂O₅分别节省42.84%、 52.67%。滴灌施肥对菠萝的产量、 商品品质以及经济效益提高有积极影响。

Abstract: Field experiment was conducted in Xuwen county to investigate the effects of  drip fertigation and farmer practice  on pineapple yield, quality and economic benefit. The experiment has three treatments:   no fertilizer (CK), farmer’s practice (FP) and drip fertigation (DF). The results show as follows: The yield of DF is 81405 kg/ha and the rate of commodity fruit is 95.73%, increased by 39.04% and 11.51% respectively than those of FP. Applying drip fertigation can increase the net income by 69670 yuan/ha, save labor costs 1125 yuan/ha, N and P₂O₅ 42.84% and 52.67% respectively, and promote by the input-output ratio from 2.00∶1 to 2.97∶1 compared with FP. So drip fertigation has positive effect on the yield, the rate of commodity fruit and economic benefit of pineapple.
