Due to problems in chemical fertilizers, pesticide application and management techniques in recent years, the production of green onions in the main producing areas of northern China has dropped significantly, and domestic prices have risen rapidly  If we want to maintain domestic prices, we must strictly limit the export of green onions  Because the export contracts of companies engaged in the export trade of green onions are signed at low prices, if they continue to perform the contracts when the price of green onions rises sharply, these companies will suffer serious losses
If the export of green onions is strictly restricted, domestic prices of green onions will not continue to rise.
 However, if the export of green onions is strictly restricted, China's share of the international green onion market will be replaced by other countries or regions
