1962年以前,元江县的低热河谷地带仅有果实小、核大、肉薄的一种本地大核芒,商品价值不大。这个县的农、林科委等部门为了把热区自然优势变为经济优势,从1962以来,先后从省内外引进芒果品种68个栽培试验。经过多年的观察研究,到八十年代,已筛选出适宜当地热区山地土壤、气候条件,且丰产性能好、抗逆性强,果实品味较佳的3年芒、柳香芒、大青蜜、象牙
Before 1962, the low-heat river valley in Yuanjiang County had only a small local fruit with a large fruit core and a thin flesh. The value of the commodity was not large. In order to transform the natural advantages of the hot zone into an economic advantage, the agricultural, forestry and science commission and other departments of the county have introduced 68 cultivation trials of mango varieties from 1962 since the introduction of the province. After many years of observational research, in the 1980s, 3-year-old Mount Mangosteen, Mangosteen, Mangosteen, Mangosteen, Mangosteen, Mangosteen and Mangosteen have been screened for suitable soil and climatic conditions in the mountainous areas of the hot area. ivory
