摘　　要：以7~8年生荸荠种杨梅树为试材,在2020─2021年杨梅植株盛花期后进行了不同疏花处理,研究了不同天气背景下疏花对杨梅花序坐果和果实性状的影响,以期能够适应杨梅生产劳动力紧张的现状,尽量减少化学药剂的使用,实现杨梅的优质生态高效稳产。结果表明:花期正常天气条件下,微量浓度(1小包疏花剂兑水40 kg)处理的疏花效果不佳;减量浓度(1小包疏花剂兑水20 kg)处理有一定的疏除效果;常量浓度(1小包疏花剂兑水13 kg)处理在花期遇0~2℃低温时将出现严重叠加影响。因此,调节荸荠种杨梅树体负载,应区分不同天气背景,根据盛花期中果枝平均花序数量,在严格控制化学药剂使用的前提下综合施策。In order to adapt to the current situation of labour constraints in Myrica rubra production,minimize the use of chemicals and achieve high quality,ecologically efficient and stable production of Myrica rubra,the 7~8 years old Myrica rubra cv.Biqi trees were used as materials,and different flower thinning treatments were made after the full-bloom stage during 2020—2021.The effects of flower thinning on the fruit setting of inflorescence and fruit characters of Myrica rubra under different weather conditions during flowering period were studied.The results showed that the effect of micro-concentration(1small packet of flower thinning agent mixed with 40 kg of water)on flower thinning was not good under normal weather conditions during flowering period.The decrement concentration(1 small packet of flower thinning agent mixed with 20 kg of water)had a certain effect of flower thinning.The constant concentration(1 small packet of flower thinning agent mixed with 13 kg of water)would have a serious superimposed effect when it met the low temperature of 0~2℃during flowering period.Therefore to regulate the load of Myrica rubra cv.Biqi trees,different weather backgrounds should be distinguished,and then a comprehensive approach should be adopted under strict control of chemical use according to the average number of inflorescences of fruit branches at full-bloom stage.
