| 中文摘要: |
| 研究花期喷施不同浓度（10、20、30、40 mg/kg）赤霉素（GA3）和环割对灵武长枣生长发育、坐果及果实品质的影响。结果表明：GA3和环割提高1 a主枝叶片光合作用。
30 mg/kg的GA3处理显著促进1 a主枝枣吊伸长和加粗生长，环割处理枣吊长度和粗度与CK无显著性差异。20-40 mg/kg的GA3和环割能显著提高坐果率，但降低了果实横径、单果重。GA3和环割提高了灵武长枣果实Vc、可滴定酸含量，GA3降低了果实可溶性固形物、可溶性糖、糖酸比，环割处理可溶性固形物、可溶性糖、糖酸比与ck无显著性差异。结合主成分分析结果和坐果率情况，生产上喷施20 mg/kg的GA3，建议采用环割来调控树体生长。 |

| In the present study, the effect of GA3 (10、20、30、40 mg/kg)and Girdling healing on growth, fruit?set, quality of Lingwuchangzao was explored. It was shown that GA3 and Girdling healing increased leaves, photosynthesis of 1a main branch. 30 mg/kg GA3 could promote the long and thicking growth of 1a bearing branch significantly. There was no significant effect between Girdling healing and CK of long and thicking of bearing branch. 20-40 mg/kg GA3 and Girdling healing increased fruit set significantly, decreased fruit diameter and single fruit weight. GA3 and Girdling healing increased fruit VC and titratable acid, GA3 decreased the soluble solids, soluble sugar, sugar acid ratio. There was no significant effect between Girdling healing and CK of the soluble solids, soluble sugar, sugar acid ratio. Combined with the principal components comprehensive and fruit set, 20 mg/kg GA3 was sprayed on the production,and it was suggested to use girdling to control tree growth. |
