| 中文摘要: |
| 通过配合施用液硼（B≥140g/L）、99%磷酸二氢钾，以及喷施不同浓度的75%赤霉酸、0.0075%14-羟基芸苔素甾醇、5%苄胺基嘌呤、1.8%复硝酚钠等处理，研究不同处理对蜂糖李坐果的影响。结果表明，配合施用500倍硼液+500～1000倍磷酸二氢钾，对花期坐果率提升明显，最大坐果提升率为60.9%；而使用1000倍硼+333～1000倍磷酸二氢钾，对幼果期坐果率提升效果明显，且随磷酸二氢钾浓度增加，坐果率提升效果越明显，最大坐果提升率可达327.3%。喷施500倍苄胺基嘌呤或25000倍赤霉酸，可明显提升蜂糖李花期坐果率，坐果提升率分别为51.1%和56.9%；喷施2500倍复硝酚钠或15000～25000倍赤霉酸，可明显提升幼果期坐果率，且随着赤霉酸浓度增加，坐果率提升效果越好。其中，15000倍75%赤霉酸结晶粉剂处理坐果提升率最大，为109.1%；但喷施14-羟基芸苔素甾醇对坐果率提升不明显。 |
| 英文摘要: |
| By applying liquid boron (B≥140g/L) and 99% monopotassium phosphate in combination, and spraying different concentrations of 75% gibberellic acid, 0.0075% 14-hydroxylated brassinosteroid, 5% benzylaminopurine, and 1.8% sodium nitrophenolate, the effects of different treatments on the fruit setting of honey plum were studied. The results showed that the combined application of 500-fold boron solution + 500～1000-fold monopotassium phosphate significantly improved the fruit setting rate during the flowering period, with a maximum increase of 60.9%. The use of 1000-fold boron + 333～1000-fold monopotassium phosphate significantly improved the fruit setting rate during the young fruit stage, and the effect became more pronounced with increasing concentration of monopotassium phosphate, reaching a maximum increase of 327.3%. Spraying 500-fold benzylaminopurine or 25000-fold gibberellic acid significantly increased the fruit setting rate during the flowering period, with increases of 51.1% and 56.9%, respectively. Spraying 2500-fold sodium nitrophenolate or 15000～25000-fold gibberellic acid significantly improved the fruit setting rate during the young fruit stage, and the effect was better with higher concentrations of gibberellic acid. Among these, the 15000-fold 75% gibberellic acid crystalline powder treatment resulted in the highest increase in fruit setting rate, at 109.1%. However, spraying 14-hydroxylated brassinosteroid did not significantly improve the fruit setting rate. |
