水肥一体化技术在桂柚1号果园应用的效果
Application Effect of Water and Fertilizer Integration Technology in Guiyou No. 1 Orchard

为探索山地柚园水肥一体化应用的技术与效果，以桂柚1号为研究对象，研究水肥一体化施肥和常规施肥对果实产量、品质及果园经济效益的影响。结果表明：采用水肥一体化施肥，可减少浇水与淋肥人工92.14%，节约喷药人工成本90%，年节水46.67%、节肥14.45%；桂柚1号产量提高35.37%，果实重量比常规施肥增加19.11%，维生素C、还原糖、转化糖和总糖含量分别提高9.10%、12.14%、2.46%和2.64%，可溶性固形物含量持平，可滴定酸含量降低16.67%，果实风味无明显差异。山坡地桂柚1号果园应用水肥一体化装备与技术能够实现节水减肥、提高果实产量和品质的目标。
To explore the application effects of water and fertilizer integration technology in mountain pomelo orchard, taking Guiyou No. 1 as test material, a comparative study was conducted on fruit yield, quality and orchard economic benefit under water-fertilizer integration and conventional fertilization. The results showed that, water and fertilizer integration could reduce the artificial amount of watering, fertilization and spraying by 92.14% and 90%, saving water by 46.67% and fertilizer by 14.45%. Compared with conventional fertilization, the yield of Guiyou No. 1 was increased by35.37%, fruit weight was increased by 19.11%, vitamin C, reducing sugar, invert sugar and total sugar contents were increased by 9.10%, 12.14%, 2.46% and 2.64%, respectively; titratable acid content was decreased by 16.67%. But soluble solid content was kept the same, and there was no significant difference in fruit flavor. The integrated equipment and technology of water and fertilizer can achieve the goal of saving water and reducing fertilizer, improving fruit yield and quality in Guiyou No. 1 orchard on hillside land.
