摘　　要：以石硖龙眼树为试材,对其进行管道输液（CK）、管道输液＋地表滴灌（T1）、管道输液＋地下10cm滴灌（T2）、管道输液＋地下20cm滴灌（T3）、管道输液＋地表多孔滴灌（T4）处理,调查其对树体生长,土壤状况和果实产量和质量的影响。结果表明：30d后,T1、T2、T3、T4叶片SPAD值增加量分别比CK提高37.5%、100%、125%、187.5%;T4的枝梢增长量最大,梢长和梢粗分别比CK提高128.34%和110.81%;不同处理在0~100cm土层,土壤含水量大致在15%~35%波动;土壤全氮、全磷和全钾主要集中0~40cm土层;T4果实横径、纵径、单果重、单株产量、可食率和可溶性固形物均比其他处理高,比CK分别提高5.45%、2.58%、8.64%、34.31%、2.85%及26.39%。In this study, Longan cv. Shixia is taken as test materials and conducted with four different treatments, namely pipeline infusion（CK） ,pipeline infusion ＆ subsurface drip irrigation（T1）, pipeline infusion ＆ 10cm underground drip irrigation（T2）,pipeline infusion ga 20cm underground drip irrigation（T3）, pipeline infusion ＆ surface of porous drip irrigation（T4）, and the tree growth, soil condition, fruit yield and quality are investigated. The results indicated that., after 30 days, compared with CK, the leaf SPAD values of T1, T2, T3 and T4 are increased by 37. 5 %, 100%, 125 %and 187.5%, respectively; branch length and diameter of T4 are increased by 128. 34% and 110. 81 %, respectively and reached the highest; the soil moisture content of 0 to 100 cm soil layer fluctuates approximately from 15% to 35 % for different treatments; the total nitrogen, total phosphorus and total potassium of soil mainly concentrate on the 0-40 cm layer; the longitudinal diameter, transverse diameter, single fruit weight, single plant yield, edible rate, soluble solids content of T4 are higher than those of other treatments and increased by 5.45%, 2.58%, 8. 64%, 34.31%, 2.85 % and 26.39 %, respectively, when compared with CK.
