摘　　要：以"桂香"、"早熟一号"龙眼品种为试材,比较了管道输液施肥和常规土施对龙眼果实生长、产量和果实品质的影响。结果表明:管道输液显著提高了果实品质,果实纵横径、单果重、单株产量、可食率、可溶性固形物和可溶性糖含量均优于土施处理。"桂香"和"早熟一号"龙眼的输液处理比土施处理的纵径分别提高了3.24、2.40mm,横径分别提高了0.72、2.45mm;"桂香"和"早熟一号"龙眼的输液处理比土施处理的单果重分别提高了19.57%、20.28%;单株产量分别提高了23.23%、5.73%;可食率分别提高了4.45%、5.27%;可溶性固形物含量分别提高了10.83%、17.24%;可溶性糖含量分别提高了18.89%、10.48%。管道输液还有效地提高了龙眼果实矿质营养元素N、K、Ca的含量,但对果实矿质营养元素P和Mg的含量影响不明显。"桂香"和"早熟一号"龙眼的输液处理比土施处理的果实N含量分别提高了17.37%、23.27%;果实K含量分别提高了12.93%、17.30%;果实Ca含量分别提高了32.33%、16.96%。Taking ＇Guixiang＇ and ＇Zaoshu 1＇ longan varieties as test materials, the influence of pipeline infusion fertilization and soil application processing on fruit growth, yield and fruit quality were compared. The results showed that pipeline infusion fertilization significantly improved fruit quality, fruit vertical and horizontal diameter, single fruit weight, yield per plant, edible percentage, soluble solid and soluble sugar than soil application processing. ＇Guixiang＇ and ＇Zaoshu 1＇ under pipeline infusion fertilization increased longitudinal diameter than soil application of 3. 24 ram, 2. 40 mm,the transverse diameter increased 0. 72 mm, 2. 45 ram; the pipeline infusion treatment on ＇Guixiang＇ and＇Zaoshu 1＇ increased single fruit weight by 19. 57 % and 20. 28% than soil application;yield per plant were increased by 23. 23% ,5. 73%the edible rate were increased by 4. 45%, 5. 27%soluble solids content were increased by 10. 83% to 17. 24%;soluble sugar content increased by 18. 89%, 10. 48% respectively. Pipeline infusion effectively improved the longan fruit mineral nutrient elements N,K and Ca content,fruit mineral nutrient elements of P and Mg content was not obvious. Pipeline infusion on ＇Guixiang＇ and ＇Zaoshu 1＇ longan increased fruit N content than soil application process by 17. 37% ,23. 27% and K content were increased 12. 93% ,17. 30 the% ;Ca content increased by 32. 33% and 16. 96%.
