摘　　要：开展百香果涌泉灌试验,设置1200m^(3)/hm^(2)(BI1)、1500 m^(3)/hm^(2)(BI2)、1800 m^(3)/hm^(2)(BI3)、2400 m^(3)/hm^(2)(BI4)4种灌溉定额,研究不同处理对百香果产量和品质的影响。结果发现,适当增加灌水量有助于百香果增产,其中BI4单果重、产量最高,BI2果径最大。但灌水过多不利于百香果品质的提升,各试验处理中,BI1、BI2果实锤度较高,BI3、BI4相对较低。采用模糊数学的隶属函数方法计算各处理的加权值,所得结果如下:BI2>BI4>BI1>BI3,说明BI2对百香果的灌溉效应最佳。The bubble irrigation experiment of passion fruit was carried out.Four irrigation quotas of 1200 m^(3)/hm^(2)(BI1),1500 m^(3)/hm^(2)(BI2),1800 m^(3)/hm^(2)(BI3)and 2400 m^(3)/hm^(2)(BI4)were set to study the effects of different treat⁃ments on yield and quality of passion fruit.The results showed that appropriate increase of irrigation water could in⁃crease the yield of passion fruit,among which BI4 rendered the highest single fruit weight and yield,and BI2 ren⁃dered the largest fruit diameter.Excessive irrigation water was not favorable for the quality improvement of passion fruit.Of all experimental treatments,the fruit brix of BI1 and BI2 were higher,while that of BI3 and BI4 were rela⁃tively lower.The membership function method of fuzzy mathematics was used to calculate the weighted values of all treatments,and the calculation results were as follows:BI2>BI4>BI1>BI3,indicating that BI2 had the best irrigation effect on passion fruit.
