丰水梨品质虽好,但存在易发生蜜病的缺点。日本几个梨产区的果树试验场正在进行蜜病发生机制及其防治方法的研究。 7月把盆栽的丰水梨树搬进人工气候室,进行低温(白天23℃,夜间25℃)和高温(白天33℃,夜间25℃)处理。试验表明,低温处理的梨果比重下降。硬度也降低,果肉早熟,蜜病发生严重。从盛花后143天开始,每隔7天连续采收3次 Feng Shui pear quality is good, but there is the defect prone honey disease. Fruit pests in several pear-producing areas in Japan are undergoing research on the mechanism of honey disease and its prevention and treatment. In July, the bonsai plum trees were moved to the climatic chamber for treatment at low temperature (23 ℃ during the day, 25 ℃ at night) and high temperature (33 ℃ during the day and 25 ℃ at night). Experiments show that the proportion of low-temperature treatment of pear decreased. Hardness is also reduced, pulp premature, honey disease serious. 143 days after the full bloom, harvesting every 3 consecutive 7 days
