| 摘 要：研究不同栽植密度对广西农科院园艺研究所自主选育的大果甜杨桃1号、大果甜杨桃3号果实产量及品质的影响，旨在选择最合适大果甜杨桃栽培的密度，为生产高产优质的大果甜杨桃、完善甜杨桃相关高效栽培技术提供理论依据。试验采用4组不同的栽植密度（22株/667m2、44株/667m2、88株/667m2、176株/667m2）处理，连续测定第3年、第4年、第5年果树的产量及果实品质生理指标。研究结果表明：不同的栽植密度对大果甜杨桃果实产量的影响差异显著，当栽植密度为88株/667m2时，5年生杨桃树产量达到最大且高于其他处理组；而果实品质指标与22株/667m2、44株/667m2的2个栽植密度间差异不显著。对栽植密度为176株/667m2的4年生杨桃树间伐至栽植密度88株/667m2，栽培的第5年杨桃果实产量明显提高，但仍然低于最初按照88株/667m2密度栽培的产量。结论：4种密度试验中，大果甜杨桃栽植密度为88株/667m2时产量最高，果实品质好，经济效益最大为最佳栽植密度，可在生产上广泛应用推广。 |

| Abstract：The ami was to study the effects of different planting densities on Averrhoa Carambola fruit production and quality of new selected varieties including Averrhoa Carambola cultivar ‘Daguotianyangtao‘1’, ‘Daguotianyangtao‘3’of horticultural research institute of Guangxi academy of agriculture science, to find out the suitable planting density for Averrhoa Carambola and provide some reference for producing high yield and quality of Averrhoa Carambola.. Experiment with four groups of different planting density (22 per 667m2、44 per 667m2、88 per 667m2、176 per 667m2), determination the yield and quality of three、four、five years old carambola tree. When planting density of 88 per 667m2, the yield of five years old carambola trees were highest than other treatment groups, but there was no significant difference comparing to the planting density at 22 per 667m2 and 44 per 667m2.when planting density of 176 per 667m2 of the four years old carambola trees were cutted to planting density of 88 per 667m2, the yield of carambola fruit increased significantly at the fifth years, but still lower than the original according to the density of 88 per 667m2. The result showed that the different planting densities and different planting year were significant difference on yield of Averrhoa Carambola. The best planting density was 88 per 667m2 |
