摘要

为探究广西百色右江河谷地区芒果灌溉制度，在广西田东县建立13.33 hm2芒果高效节水灌溉制度大田试验区。通过设置5种不同灌溉定额、15种不同灌溉次数、5种不同灌溉时间，累计25种灌溉处理水平，无灌溉作为对照组。结果表明：（1）百色右江河谷地区芒果最佳灌溉定额分别为：1500m3/hm2。与无灌溉相比，产量平均增加70.16%，无胚果单果重平均增加13.28%，正常果单果重平均增加7.94%。SS、TSS、VC含量分别增加7.07%、19.08%、18.77%，TA含量减少24.23%；（2）百色右江河谷地区芒果最佳灌溉时间和次数分别为：秋梢抽发期灌水1次、花芽分化期灌水1次、开花挂果期灌水2次、果实膨大期灌水2次、成熟期不灌溉。与无灌溉相比，亩均增产61.94%，可食率增加11.27%，SS含量增加9.58%，Vc含量增加8.87%。研究出芒果灌溉制度可为广西百色地区芒果高效节水灌溉提供技术支撑。

Abstract

According to the climatic characteristics of the Youjiang Ｒiver valley in Baise，Guangxi，a study on the irrigation system of mango in that area is carried out． By setting five kinds of irrigation quota，twenty kinds of irrigation time and times，no irrigation as the control group，a total of 26 kinds of irrigation treatments are carried out to compare the field mango irrigation system． The results show that in Youjiang Valley of Baise，the optimum irrigation quota of mango is about 1 500 m3 /hm2 ，the optimal irrigation time and times were 1 time at the autumn shoot shooting stage，1 time at flower bud differentiation stage，2 times at fruiting and flowering stage，2 times at period stage， and no irrigation at maturity． Compared with the no irrigation treatment，the yield of the best quota treatment is increased by 70．16%，the no embryo weight per fruit is increased by 13．28% on average，the normal fruit is increased by 7．94% on average，and the content of SS，TSS and VC is increased by 7．07%，19．08% and 18．77%，respectively，while the TA content is decreased by 24．23%． The yield of the best irrigation time and times treatment is increased by 57．93%，the no embryo weight per fruit is increased by 13．13%，the average fruit weight of normal fruit is increased by 6．84%，and the content of SS，TSS and VC is increased by 8．55%，13．71%，7．49%，respectively，while the TA content is decreased by 18．52%． The mango irrigation regimes developed in this paper can provide technical support for mango efficient water saving irrigation in Baise，Guangxi．
