★ Main characters of the variety
Indica two-line hybrid rice varieties.
The whole growth period of double cropping late rice in South China is 117.2 days, 1.4 days longer than that of the control Boyou 998. The plant height is 103.2 cm, the spike length is 24.8 cm, the effective spikes per mu are 154000, the total grains per spike are 160.6, the seed setting rate is 83.7%, and the 1000 grain weight is 25.2 g. Main indicators of rice quality: the head rice rate is 66.6%, chalky grain rate is 3%, chalkiness is 0.7%, amylose content is 14.4%, gel consistency is 70 mm, length width ratio is 3.4, reaching the second level of the standard of "Quality of Edible Rice Varieties" in the agricultural industry.

 

★ Adaptability
Output performance: participated in the regional test of South China light sensitive late indica rice group in 2017, with an average yield of 475.38 kg per mu, 3.05% more than the control Boyou 998; In 2018, the average yield per mu was 470.78 kg, 5.74% higher than the control Boyou 998; The average yield per mu in two years' regional trials was 473.08 kg, 4.37% higher than that of the control Boyou 998; In the production test in 2018, the average yield per mu was 467.12kg, 4.43% higher than that of the control Boyou 998.
Resistance: the comprehensive indexes of rice blast in two years were 5.1 and 3.6 respectively, the highest loss rate of ear neck blast was 7 levels, the highest loss rate of bacterial leaf blight was 7 levels, and brown planthopper was 9 levels; Susceptible to rice blast, bacterial leaf blight, and highly susceptible to brown planthopper.

★ Main cultivation measures
1. Cultivate seedlings by precise sowing. In the light sensitive late indica rice growing area in South China, late rice is generally sown around July 15. The amount of seed used per mu for seedling raising and transplanting is 1.5 kg, and the amount of seed used per mu for direct seeding and close planting is 1.5~2 kg. The management of fertilizer and water during seedling stage is strengthened to prevent and control rice planthoppers.
2. Planting early in time to promote tillering. Transplant at 5 leaf stage, suitable for 18-25 days of seedling age. Reasonable close planting, transplanting specification 20cm × 20 cm, planting 3 grain seedlings in each hole, and planting more than 80000 basic seedlings per mu.
3. Re apply base fertilizer, apply topdressing as early as possible, and supplement ear fertilizer according to seedlings in the later stage. The level of fertilizer demand in the field is medium to high, requiring heavy application of base fertilizer: 30~35kg of high concentration compound fertilizer or 40~45kg of common compound fertilizer per mu; Early application of tillering fertilizer: 5-7 days after planting, apply 7-8 kg urea per mu, and 20-22 days after planting, apply 8-10 kg potassium chloride per mu. Increasing potassium fertilizer application per ear and grain: in the middle booting stage, 12~15kg potassium chloride is applied per mu to promote large ears, multiple grains and strong seeds, and nitrogen fertilizer is controlled in the later stage.
4. Scientific water management and pest control. Turn green with inch water, tiller in shallow water and wet water, enough for seedlings to dry in the field, keep shallow water at booting and heading stage, fill in dry and wet alternately, and drain water 6 to 8 days before harvest.
5. Timely prevent and control pests and diseases. Persist in soaking seeds with strong chlorine. The rice planthopper was controlled by spraying pesticide in time at seedling stage to prevent southern black streaked dwarf disease. In the field period, according to the disease and pest forecast, timely apply pesticides to prevent and control the Chilo suppressalis, Chilo suppressalis, rice planthopper, bacterial leaf blight, southern black streaked dwarf disease, sheath blight and other diseases and pests, and pay attention to strengthening the prevention and control of ear neck blast.

★ Suitable planting area
It is suitable to plant late rice in the areas with low incidence of rice blast of double cropping rice in Guangdong Province (except the rice growing areas in northern Guangdong), southern Guangxi, Hainan Province, and southern Fujian Province, but not in the areas with high incidence of rice blast.

★ 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.
