杧果花期延迟技术研究进展

杧果Mangifera indica花期大多集中在2～3月，易受低温阴雨天气影响，导致其授粉受精不良、落花落果，并加重白粉病和炭疽病的危害。本文简要介绍低温阴雨天气对杧果花期的影响，并详细阐述生产上推迟花期的常用措施，如回缩、重修剪、摘花穗、抹花、应用植物生长调节剂、采后灌水、培养二次秋梢或利用冬梢结果等，为杧果开花调控及花期管理提供参考。

A Review of Delaying Flowering in Mango

Mangifera indica has been considered a famous tropical fruit tree in the world. The flowering date of mango is mainly from February to March. At the flowering stage, it is susceptible to the damages of low temperature and rainy weather, which causes poor pollination and fertilization resulting in blossom and fruit dropping, and aggravates the harm of powdery mildew and anthracnose. The influence of low temperature and rainy weather to mango flowering was briefly reviewed, and various commonly used measures in production to delay flowering, such as cutting-back, serve pruning, cutting the whole spike, flower treatment, the application of plant growth regulators, irrigating water after harvest, the cultivation of second autumn shoot or the utilization of winter shoot to bear fruit were summarized in detail in this paper. It provides a scientific basis for mango flowering regulation and management.
