Scope

Main Technical Content: 3.1 Soil Management 3.1.1 Deep Tilling After autumn leaf fall and before soil freezing, conduct deep tilling or combine it with fertilizer application in date orchards once a year to improve soil aeration. 3.1.2 Mulching and Natural Grass Coverage Promote mulching or natural grass coverage to maintain the natural ecological model. Mulching involves covering the soil with crop straw or weeds, with a compacted thickness of 15–20 cm. Mulching helps preserve soil moisture, increase organic matter content, and stabilize soil temperature. Alternatively, use grass interrow mulching or green manure cultivation. Long-term grass coverage can enhance soil fertility, maintain good soil physical and chemical properties, prevent soil and water loss, and preserve the natural ecological model. However, during the growing season, timely mow the grass to maintain a height of 5–10 cm. 3.2 Fertilization 3.2.1 Fertilizer Selection Fertilizers should meet the requirements for producing pollution-free fruits, with a focus on organic fertilizers such as compost, fermented manure, animal manure, crop straw, fertilizer pellets, microbial fertilizers, and appropriate inorganic fertilizers (see Table). Table: Permitted Fertilizers for Standardized Production of Pollution-Free Dingzhou Winter Dates **Fertilizer Type** **Organic Fertilizers** Compost, fermented manure, animal manure, biogas fertilizer, green manure, crop straw, fertilizer pellets. **Inorganic Fertilizers** Mineral phosphorus fertilizer (phosphate rock powder), mineral nitrogen fertilizer, mineral potassium fertilizer, limestone. **Nitrogen, Phosphorus, and Potassium Fertilizers** Nitrogen, phosphorus, and potassium fertilizers formulated according to the optimized fertilizer scheme guided by agricultural authorities, as well as other compliant inorganic compound fertilizers. **Microbial Fertilizers** Plant growth aids made from natural organic extracts or fermentation s
