(1) Sow in time. When planting rape stubble or wheat stubble in Huanghuai area, direct seeding should be carried out from late May to early June, with sowing amount of 6-8 kg/mu, sowing depth of 2-4 cm and row spacing of 28-30 cm.

Apply ternary compound fertilizer 15 ~ 20kg per mu of base fertilizer, or apply diammonium phosphate 10 ~ 15kg plus urea 4 ~ 5kg, and add zinc sulfate1.5 ~ 2kg at the same time; Topdressing urea from tillering to jointing stage is 7.5 ~ 10 kg/mu, and booting stage is 3 ~ 5 kg/mu; (4) timely irrigation. In case of severe drought during sowing, seedling raising, jointing, booting stage to full heading and filling stage, irrigation should be done in time to ensure high yield; (5) pest control. Pay attention to control rice leaf roller, Chilo suppressalis, rice planthopper and sheath blight before and after jointing and heading, and control rice false smut at heading stage.

In 2002, the average yield per mu was 328. 1 kg, which was11%higher than the control.
Key points of cultivation
1. Sowing in time: Sowing in late April to early May. Seed dressing with seed coating agent before sowing, sowing 7-9 kg per mu. The row spacing is 25-30cm, and the sowing depth is 2-4cm; 2. Weeding: Before emergence, mix 250-350ml of "Herbicide1"28% EC or "Nongsida"12% EC with 60-80kg of water per mu. Assisted by manual weeding after emergence; 3. Fertilization: apply ternary compound fertilizer 15 ~ 20kg per mu of base fertilizer, and add zinc sulfate 1.5 ~ 2kg at the same time. Pay attention to adding organic fertilizer and potassium fertilizer. Topdressing 6-8kg urea from tillering to jointing stage and 3-5kg urea from booting stage to heading stage; 4. Irrigation in time: In case of drought, irrigation should be carried out in time, especially at the emergence, booting and filling stages; 5, pest control: attention should be paid to the prevention and control of rice blast, sheath blight, rice planthopper, stem borer and other pests.
Adaptive region
After examination, the variety conforms to the national rice variety approval standard and has passed the approval. This variety is susceptible to rice blast. Strong drought resistance.
