【摘要】 分析了浙江省慈溪市2022/2023年度杨梅生育期的温、光、水等气象条件，尤其是2022年盛夏罕见的高温干旱和后续天气对杨梅生长发育的持续影响，结果表明：盛夏罕见的高温干旱不仅会导致杨梅叶片大面积卷曲、萎蔫，以及当年移栽的杨梅幼树大量枯死，而且还严重抑制了夏梢的抽发生长和花芽分化；在旱情解除后，秋梢的大量抽发进一步影响了花芽分化和养分积累，导致花芽发育较弱，并形成了大量秋梢果；采收后期若遇高温，秋梢果则会大量变软或脱落。因此，提出了一些能有效防御高温干旱对杨梅影响的对策措施。更多还原

【Abstract】 Through the observation and analysis of temperature, light and water meteorological conditions of Myrica rubra in Cixi City, Zhejiang Province, during the growth period in 2022/2023, the sustained influence of especially rare high temperature and drought in midsummer of 2022 and the subsequent weather on growth of Myrica rubra was studied. The results showed that rare high temperature and drought in midsummer not only led to the wilting of Myrica rubra leaves and the death of a lot of young Myrica rubra plants in that year, but also seriously inhibited flower bud differentiation and the growth of summer shoots. After the drought was over, a large number of autumn shoots further affected the flower bud differentiation and nutrient accumulation,resulting in the development of weak flower buds and the formation of a large number of autumn fruits. If high temperatures is met at the end of the harvest, a large number of autumn fruits will be soft and rotting or fall off. In order to effectively defend against high temperature and drought on the hazards of Myrica rubra, the corresponding countermeasures were put forward.更多还原
