| 中文摘要: |
| 本试验研究S-诱抗素对沙糖桔Citrus reticulata Blanco cv. ‘Shatangju’的花芽分化、产量及果实品质的影响,为沙糖桔优质高产栽培技术的优化提供新的依据,也为该药剂推广至其他柑橘类果树提供技术参考。在2012-2015年间共进行两次田间试验,每次试验周期为两年。在沙糖桔树秋梢老熟、果实采收结束、春梢萌动三个时期用不同浓度1%S-诱抗素可溶粉剂进行整株喷施处理,处理浓度为1.67 mg/kg、2.50 mg/kg、3.30 mg/kg、5.00 mg/kg,1.4%复硝酚钠水剂(2.50 mg/kg)与清水作对照。观测试验对象花芽和果实的相关生理指标进行分析。经不同浓度S-诱抗素处理的沙糖桔,花芽分化、产量的各项指标数值均显著高于空白对照,其中单株产量和增产幅度随处理浓度的升高而增大。在试验浓度范围内,S-诱抗素还可以明显改善果实品质,不产生药害。当处理浓度为3.30 mg/kg时,花芽数、开花数、坐果率达到同期最大值。为使S-诱抗素处理达到最佳效果,同时考虑实际应用过程中的复杂因素,建议田间施用量以2.5-3.3 mg/kg为宜。 |

| To study the effects of S-ABA on flower bud differentiation, yield and fruit quality in Citrus reticulata Blanco cv. ‘Shatangju’, provide a new basis for the optimization of high quality and high yield cultivation technique of Citrus reticulata Blanco cv. ‘Shatangju’, also provide technical reference for the application of S-ABA to other citrus fruit trees.A total of two field trials were conducted in 2012-2015 years, with a two-year trial cycle. In the three periods of ‘shatangju’, fruit harvest, autumn shoots mature and spring shoot bud, different concentrations of 1% S-ABA |
