大番石榴是近年从泰国引种的一种早结、高产果树。目前在广州、深圳、珠海、海南、湛江、汕头、普宁、博罗、番禺和清远等县市有零星种植。估计今后有较快发展的趋势。目前,生产上存在的主要问题之一是:果实变小,大小不均,品质下降,叶干,枝枯和折干,使植株早衰,果园呈现台风后的灾害状。
Large Guava is introduced in Thailand in recent years, a early knot, high-yield fruit trees. Currently there are sporadic planting in counties such as Guangzhou, Shenzhen, Zhuhai, Hainan, Zhanjiang, Shantou, Puning, Boluo, Panyu and Qingyuan. It is estimated that there will be a trend of rapid development in the future. At present, one of the main problems in production is that the fruit becomes smaller, the size is not uniform, the quality declines, the leaf stem, the branch withered and the stem is dry and the plant prematurely declines, and the orchard presents the disaster after the typhoon.
