Organic fertilizers come from natural sources; they contain no chemically synthesized substances, and their long-term use can improve the quality of agricultural products； Chemical fertilizers are purely chemically synthesized substances, and their improper use can reduce the quality of agricultural products. （ ） 2. During the production and processing of organic fertilizers, as long as they undergo proper decomposition, their application can enhance crops’ resistance to drought, diseases, and pests, thereby reducing the need for pesticides ； The long-term use of chemical fertilizers reduces the immunity of plants, often requiring large amounts of chemical pesticides to sustain crop growth, which can lead to an increase in harmful substances in food. ( ) In the compound fertilizers and functional fertilizers section, a daily quiz on basic production knowledge is carried out. We hope that all marine enthusiasts will participate actively. The purpose of this activity is to review the knowledge we have already learned, and to improve and strengthen everyone’s fundamental theoretical knowledge through answering questions, thereby reinforcing what we already know and helping us recall what we have forgotten. The top 50 answerers will definitely receive a reward. Please reply with the answer hidden; otherwise it will be invalid.
