It has been widely noticed that industrial pollution, pesticides, and nitrates in chemical fertilizers enter the human body through the food chain, causing certain harms and even life-threatening. For this reason, people's requirements for vegetable quality are becoming more and more stringent, and the voice of producing green vegetables is getting higher and higher.
