Scope

Scope: This standard specifies the technologies for the environment of machine-transplanted rice production areas, land preparation, transplanting, fertilization, water layer management, and pest and disease control. This standard applies to the field cultivation of machine-transplanted rice; Main technical content: 1. Seedling preparation 1.1 Standard seedlings shall be selected from varieties that have been approved and promoted, are salt-tolerant, high-yielding, disease-resistant, and have a growth period of 160-175 days. The seedlings shall have 3-4.5 leaves, a plant height of about 13 cm, be uniform and well-distributed, free from withered leaves and diseases, with white roots, a large root quantity, good root entanglement, and a blanket-like root system. 1.2 Seedling preparation and transplanting shall be carried out according to the machine-transplanting schedule, with seedlings being raised, transported, and transplanted immediately to reduce the number of seedling transfers. The stacking height shall not exceed 3 layers. For long-distance seedling transportation, seedlings shall be transported in seedling trays. 2. Machine-transplanted seedlings 2.1 Transplanting time and density: Transplantation shall be carried out from May 15 to May 31. The row spacing shall be 30 cm, and the hole spacing shall be 15-18 cm, with 4-6 seedlings per hole. 2.2 Transplanting quality: The transplanting depth shall be 1.5-2.0 cm. The seedlings shall be planted upright, with straight rows and regular hole spacing, ensuring consistent depth and density. The rows shall be transplanted completely and evenly on all sides. After transplanting, water the seedlings promptly to protect them. At the same time, arrange dedicated personnel to replant missing seedlings. 3. Fertilization The application rates of N, P2O5, K2O, and SiO2 shall be 240-300 kg/hm2, 90-135 kg/hm2, 75-150 kg/hm2, and 75-150 kg/hm2, respectively (for straw returning fields, silicon fertilizer shall be omitted or
