Promotion of the Green Planting - Breeding Cycle Model: Contributing to the High - quality Development of the Fruit Industry

In the fruit - planting process, the green planting - breeding cycle model is mainly reflected in two aspects: fertilization and pest control. Regarding fertilization, instead of the traditional single - chemical - fertilizer application mode, a combination of "organic biogas residue as base fertilizer + biogas slurry compounded as top - dressing" is adopted. Organic waste such as livestock and poultry manure is fermented and transformed into nutrient - rich biogas fertilizer. It is combined with organic nutrients like amino acids and fulvic acid, and inorganic elemental fertilizers are rationally added. This can not only improve the soil structure and enhance soil fertility but also reduce the environmental pressure caused by the use of chemical fertilizers. Many production areas have also built supporting organic biogas fertilizer storage facilities to achieve standardized storage and scientific application of biogas fertilizer, ensuring the safety and standardization of fertilization. 

In terms of pest and disease control, a full - process green prevention and control technology model is established. With microbial bacteria and biopesticides at its core, it is combined with means such as physical - chemical trapping and precise pesticide application to minimize the use of chemical pesticides and safeguard the safety of fruit products and ecological balance. This prevention and control model not only reduces the risk of pesticide residues but also protects the orchard ecosystem, promotes the reproduction of natural enemies of pests and diseases, and forms a sustainable ecological prevention and control system. At present, the green planting - breeding cycle model has been promoted and applied in many fruit - producing areas across the country. Relevant technical standards are constantly being improved, covering national and industry standards such as the return of livestock and poultry manure to the fields and the return of agricultural biogas slurry to the fields, providing scientific guidance for growers. With the continuous popularization of this model, the quality and safety of fruit products have been significantly improved. This not only meets consumers' demand for healthy agricultural products but also enhances the market competitiveness of China's fruit industry, promoting the transformation of the industry from a "quantity - oriented" to a "quality - oriented" one.
