荔枝小年结果现象是少花、无花和花而不实。由于11月出现冬芽和2—3月份形成春芽,导致荔枝小花、无花。雌花过少或在低温阴雨天出现“沤花”,高温干旱发生“烧花”,造成花而不实。要克服小年结果现象,应抓好以下几项工作: 全面调控 把花芽分化和开花时期调节在最佳安全期,是配套技术的核心。荔枝在花序和花器官分化始期,需要一段相对低温的诱导期(14℃以下),才能分化形成有经济价值的花序,在广西的1月份为全年最低温度,能满足这
Litchi small annual results phenomenon is less flowers, flowers and flowers but not real. Due to the emergence of winter buds in November and spring buds from February to March, the flowers of litchi are small and without flowers. Fewer female flowers or rainy days appear in low temperature, “Sui flowers”, high temperature and drought occurred “burning flowers”, resulting in flowers and not real. To overcome the phenomenon of small-year results, we should do a good job in the following areas: The regulation and control of flower buds during flowering and flower buds are in the best safety period, which is the core of supporting technologies. Lychee in inflorescence and floral organ differentiation period, the need for a relatively low temperature induction period (below 14 ℃), in order to differentiate to form economic inflorescences, Guangxi in January for the year the lowest temperature, which can meet this
