Cultivation technology points:
1. Sow seeds at an appropriate time and cultivate strong seedlings. Generally, the seedlings are planted in mid-May.

Machine-transplanted seedlings are planted on May 20-25. Kilogram.

3. Scientific fertilizer and water management. Generally apply pure nitrogen 18-20 kg per mu, master the principle of “weight before, medium stability, and make up afterwards”, apply tillering fertilizer early, apply nitrogen fertilizer stably during jointing stage, increase phosphorus and potassium fertilizer, and apply ear fertilizer to seedlings in later period. The ratio of basal tiller fertilizer to ear fertilizer should be 7:3, and the nitrogen, phosphorus and potassium should be used in combination; in order to maintain the high-quality taste of this variety, it is advisable to apply less nitrogen fertilizer and more organic fertilizer, especially in the later period, try not to apply nitrogen fertilizer as much as possible. . In the management of water slurry, we should master shallow water and frequent irrigation in the early stage to promote early onset.
4. Prevention and treatment of diseases, pests and weeds. Before sowing, use chemicals to soak seeds to prevent seed-borne diseases such as bakanae and dry tip nematodes. Pay attention to the prevention and control of Laodelphax striatellus and rice thrips during the seedling and field stages. In the middle and late stages, comprehensive control of sheath blight, stem borers, and rice worms should be carried out.
