摘要
为探讨不同灌溉方式对芒果生长、产量与品质的影响,在广西百色田阳县那坡镇尚兴村弄蕉屯芒果高效节水灌溉示范基地设置滴灌(DI)、微喷灌(MSI)、低压管灌(LPI)3种灌溉方式与无灌溉(NI)作为对组照,开展对比试验。结果表明,DI、MSI、LPI处理较NI新梢长度、粗度、总数分别提高2.40%、4.33%、2.88%,3.85%、2.56%、5.13%,22.25%、25.17%、15.63%;灌溉较无灌溉提高了芒果的纵横径,其中DI、MSI对果型分布整体提高较为明显,LPI大幅度提高了纵径<100 mm的芒果分布;DI、MSI、LPI较NI分别增产90.91%、76.86%、43.59%;ER和V_C较NI增幅不大,仅增加4.18%、2.52%、4.88%和2.20%、2.67%、3.59%;DI、MSI、LPI处理SS和TSS较NI有显著提高,分别提高了9.45%、14.79%、8.46%和7.51%、9.62%、6.34%;TA含量DI、MSI、LPI处理较NI分别减少9.28%、5.43%、3.77%。DI、MSI可作为广西百色地区芒果主要高效节水灌溉方式推广应用。
In order to explore the effects of different irrigation methods on mango growth,yield and quality,drip irrigation(DI),micro-sprinkler irrigation(MSI),low pressure pipe irrigation(LPI)and non-irrigation(NI)were set up in the mango high efficiency water-saving irrigation demonstration base of Longjiaotun,Shangxing Village,Napo Town,Baise Tianyang County,Guangxi.The results showed that DI,MSI and LPI treatments of mango new leaves longer,coarser increased slightly than NI treatments by 2.40%,4.33%,2.88%,3.85%,2.56%,5.13%;the total number of new leaves increased by 22.25%,25.17%and 15.63%respectively.Irrigation increased the vertical and horizontal diameter of mango compared with no irrigation,among which DI and MSI increased the overall distribution of fruit types,and LPI greatly increased the vertical and horizontal diameter of mango distribution less than 100 mm;the yield of DI,MSI and LPI increased by 90.91%,76.86%and 43.59%respectively compared with NI;ER and V_C increased by only 4.18%,2.52%,4.88%and 2.20%,2.67%and 3.59%compared with NI;SS and TSS increased by 9.45%,14.79%,8.46%and 7.51%,9.62%,6.34%;TA increased by only 4.18%,2.67%,3.59%.Compared with NI,it decreased by 9.28%,5.43%and 3.77%respectively.DI and MSI can be widely used as the main efficient and water-saving irrigation methods for mango in Baise area of Guangxi.
