Main Technical Content: Comprehensive Technical Specifications for Green Fruit Production 1. Scope This document provides factors affecting green fruit production and production measures. It is applicable to green fruit production. 2. Normative Reference Documents There are no normative reference documents for this document. 3. Factors Affecting Green Fruit Production 3.1 Harmful Gases. With the rapid development of industry, mining, and transportation, air pollution has become increasingly severe. These pollutants can directly harm fruit trees, affect photosynthesis, and accumulate in plants and fruits, which can easily cause acute or chronic poisoning after consumption. 3.2 Soil Pollution. Soil pollution has a severe impact on plants. Plants grown in contaminated soil can accumulate harmful substances and, through the food chain, harm human health. 3.3 Fertilizers. Excessive nitrogen fertilizer application can produce carcinogenic nitrosamines, which pose great harm to humans. Phosphate fertilizers are a source of harmful metals in soil, with high concentrations in calcium, magnesium, and phosphate fertilizers. Calcium phosphate contains large amounts of cadmium, arsenic, lead, and phosphorus, while ore also contains radioactive elements such as uranium and radium. Chloride ions in potassium chloride can cause soil compaction, negatively affecting fruit production and quality. 3.4 Pesticides. After pesticide application, some dispersed onto the soil (sometimes directly applied to the soil), evaporated and dispersed into the air, or flowed into rivers and lakes with rainwater and farmland drainage, contaminating water bodies and aquatic organisms. Residual pesticides in agricultural products can contaminate livestock products through feed. Pesticide residues eventually enter the human body through the air, water, soil, and food, causing various chronic or acute diseases. 3.5 Plastic Pollution. Once old plastics enter the soil, they are difficult
