为了探讨芒果丰产技术，消除生产中的大小年现象，通过使用合理修剪、施肥和病虫防治，隔年施一次15％多效唑（PP333）15～30g／株，于10月份土施并保湿2周，摘除2月上旬前抽出的花芽，使花期推迟至3月中旬以后等技术，试验的4．4km2果园连续4年丰收，平均年产29169．5kg／km2。
In order to explore the mango high yield technology and eliminate the size year-round phenomenon in production, 15-30 g / PP333 was applied every other year by using reasonable pruning, fertilizing and pest control, soil was applied and moisturized for 2 weeks in October, Excluding the flower buds that were taken before early February, the flowering period was postponed till mid-March, and the other 4.4km2 orchards were harvested for four consecutive years with an average annual yield of 29,169.5kg / km2.
