Scope

Main Technical Content: 3.1 Soil Management 3.1.1 Deep Tilling After autumn leaf fall and before soil freezing, deep tilling or combined fertilization should be carried out in date orchards once a year to improve soil aeration. 3.1.2 Mulching and Natural Vegetation Vigorously promote mulching or natural vegetation systems to maintain the natural ecological model. Mulching involves covering the ground with crop straw or weeds, with a compacted thickness of 15–20 cm or more. Mulching helps preserve soil moisture, increase organic matter content, and stabilize soil temperature. Grass inter-row cultivation or green manure planting can also be used. Long-term vegetation cultivation can enhance soil fertility, maintain good soil physical and chemical properties, prevent soil and water loss, and preserve the natural ecological model. However, grass should be cut regularly during the growing season and kept at a height of 5–10 cm. 3.2 Fertilization 3.2.1 Fertilizer Selection Fertilizers should meet the requirements for pesticide-free fruit production, with a focus on organic fertilizers such as compost, fermented manure, animal manure, crop straw, fertilizer cakes, microbial fertilizers, and inorganic fertilizers used in moderation (see Table).
