‘爱媛38号’柑橘保花保果技术试验初报

Preliminary Report on Flower or Fruit Retention Technology Experiment of‘Aiyuan 38’Citrus

研究不同保花保果技术措施对‘爱媛38号’的实际应用效果,为指导柑橘花果管理提供理论依据。以南充地区主栽品种‘爱媛38号’为试材,设置9种保花保果处理,分析不同处理对落花落果量、坐果率及落花落果规律的影响。结果表明,‘爱媛38号’落果量远大于落蕾落花量,且以第一次生理落果为主;各处理坐果率差异不显著,但用三十烷醇处理后,坐果率最高。综上所述,‘爱媛38号’保花保果重点在第一次生理落果期,对其更有效的保花保果措施还需进一步研究。

This article studies the practical application effects of different flower and fruit retention techniques on‘Aiyuan 38’to guide citrus flower and fruit management.Using the main variety‘Aiyuan 38’in Nanchong area as the test material,nine flower and fruit retention treatments were set up to analyze the effects of different techniques on the quantity and pattern of flower and fruit loss and the fruit-setting rate.The results showed that the fruit drop was much higher than the bud and flower drop,with the first physiological fruit drop being predominant.Although the difference in fruit setting rate among different treatments was not significant,the highest fruit setting rate was observed after treatment with triacontanol.In summary,the emphasis for‘Aiyuan 38’flower and fruit retention should be on the first physiological fruit dropping period,and more effective measures for flower and fruit retention techniques still need further research.
