ZONING AGRO-CLIMATIC FACTORS AND EVALUATING ADAPTATION ABILITY OF ARABICA COFFEE IN MUONG ANG DISTRICT, DIEN BIEN PROVINCE

Tóm tắt

Muong Ang is a mountainous district in the middle of Dien Bien province (the northwest of Viet Nam). Its climatic conditions are quite different compared to the surrounding areas. Specifically, mountainous terrain with a high slope and severe division leads to considerably differentiation in terms of meteorological and hydrological conditions. Muong Ang district is characterised by humid tropical monsoon climate; there are many extreme weather phenomena, e.g. heat wave, unevenly distributed large rainfall, diurnal temperature variation, large seasonal temperature variations. Besides, natural disasters occur quite frequently, such as erosion, landslides, floods and droughts [4]. However, the difference between agricultural meteorology and topography has created a unique landscape in Muong Ang, which is suitable for many kinds of tropical plants with high economic value. Typically, Arabica coffee can adapt very well to the climatic conditions in Muong Ang with high productivity and good quality, which is gradually forming the Muong Ang coffee brand in the domestic and international market.

In order to confirm the correctness of selecting Arabica coffee to be the main crop in the economic development orientation of Muong Ang district, we need to study the agro-climatic conditions and the agro-climatic zoning of the district and assess the ecological adaptation ability of the coffee in the ecological conditions of Muong Ang, Dien Bien province.
