Key Production Techniques for Green Food German Bunching Onion
1 Base Conditions The production base for green food German bunching onion should be selected in areas with unpolluted air and a good ecological environment, away from industrial and mining areas, main highways and railway lines, and avoiding the influence of industrial and urban pollution sources.
