★ Main cultivation measures
In the middle and late April, the seeding amount per mu of seedling field is 7.0kg, the seed consumption per mu of field field is 1.0-1.2kg, and the seedling age is within 30 days. Planting density 20.0cm × 26.7cm, 2-3 grain seedlings are planted in each hole, and the basic seedlings per mu are about 80000. Sufficient base fertilizer, top dressing speed, combined application of nitrogen, phosphorus and potassium, and appropriately increase the amount of phosphorus and potassium fertilizer. Deep water living stump, shallow water tillering, timely drying the field, water strong bud heading, dry and wet in the later stage, not dehydrating too early. Pay attention to the prevention and control of rice blast, bacterial leaf blight, sheath blight, rice false smut, southern black streaked dwarf disease and other diseases and pests.

★ Suitable planting area
It is suitable for planting late maturing middle rice in the area with low incidence of rice blast in Hunan Province.

★ Planting season
Please pay attention to sowing and scientific management according to the specific arrangements of local climate, previous crops, seedling raising mode and planting habits, and according to the accurate time guided by the local agricultural technology department.
