For many garlic farmers, according to their traditional garlic planting concept, in order to increase the output of commercial garlic, efforts are made to avoid producing poisonous garlic. Garlic farmers in many places began to plant poisonous garlic, and analyzed the reasons. They thought that poisonous garlic was round in shape, easy to peel, process and eat, and was well received by consumers, so the market demand was high.
