| 琯溪蜜柚晚夏梢抽稍影响树体营养，降低蜜柚食用和商品价值。本文通过调查分析蜜柚晚夏梢发生的因素，以期为降低晚夏梢的抽生提供科学依据。结果表明：2016年蜜柚晚夏梢抽生Ⅲ级果园占比为65.52%，比2018年增加56.66%；高挂果量果园中Ⅲ级晚夏梢果园仅占16.95%，而低挂果量果园占52.80%；高树龄果园中的Ⅲ级晚夏梢果园比低树龄果园少43.47%；氮肥施用量高的果园比施用量低的果园中的Ⅲ级晚夏梢果园多43.62%；其中，高量施用硝态氮肥的果园中Ⅲ级晚夏梢果园比低量多47.13%；膨果期施肥次数多的Ⅲ级晚夏梢果园较施肥次数少的增加37.75%；膨果期施氮肥比例高的果园中的Ⅲ级晚夏梢果园较低量的多35.19%；低海拔果园中的Ⅲ级晚夏梢果园比高海拔多29.58%。为减轻晚夏梢抽生，应因地制宜调整各养分结构，调控挂果量，合理选择肥料施用量、施用时间和形态。 |

| 【Objective】 of pomelo late summer shoot smoke slightly affect tree body nutrition, reduce the pomelo of food and commodity value, to improve the economic benefit, increase farmers' economic benefits, this paper for GuaGuo quantity, year, age, fertilization, altitude analysis discussion, in order to reduce the occurrence of late summer shoot provide scientific basis.【Result】 The findings indicate that, 1) The imbalance of late summer shoots in orchards in different years, Among them, in 2016, the class of late summer shoot orchards were 65.52%, In 2018, only 8.86 percent; 2) The increase of fruit production slows down the late summer shoots, High fruit yield of orchards is only 16.95%, Compared with the low fruit yield orchard reduced by 52.80%; With the increasing age of the fruit trees, The phenomenon of honey pomelo in late summer shoots gradually decreases, The age is larger than the year of late summer orchard less 43.47%; 3) The high proportion of late summer orchards increased by 43.62%; among, High amount of nitrate nitrogen fertilizer extraction is slightly the most obvious, Compared with the low volume, The late summer shoot orchard increased by 47.13%; The amount of high fertilizer and the low quantity type of late summer shoot orchard increased by 39.40%; 4) The more fertilization times during the fruit expansion period, The worse the late summer shoot condition is, The number of fertilization more class late summer tip orchard than less fertilization more 37.75%; among, The high proportion of nitrogen fertilizer application during the fruit expansion period is more obvious, High amount and low amount of late summer shoot orchard high 35.19%; 5) The higher the altitude is conducive to reduce the late summer shoots, Low altitude type of late summer shoot orchard is 29.58% more than high altitude; Regions are different, In late summer, Pinghe county class late summer tip orchard more than Xiapu County 22.55% more.【Conclusion】 Comprehensive analysis, the different years, the amount of fruit and the amount of fertilizer are the three important factors affecting the late summer tip of Guanxi honey pomelo. In order to reduce the late summer tip, we should adjust the nutrient structure according to local conditions, control the amount of fruit, and reasonably choose the amount and form of fertilizer in each period. |
