Onions are a long-day crop, and without sufficient sunlight, onion yields will be greatly reduced. Onions have moderate requirements for water and air humidity, and the ideal soil for cultivation should be loose, fertile, neutral soil with good aeration. The growing conditions of onions indirectly determine the distribution of their cultivation areas. So in our country, what are the main onion-producing areas and the main geographic distribution of cultivation? Let's take a look together below.
