★ Main characters of the variety
Indica two-line hybrid rice varieties.
In the middle and lower reaches of the Yangtze River, the whole growth period of a single season of medium rice was 131.6 days, 3.6 days earlier than the control Fengliangyou No. 4. The plant height is 117.3 cm, the ear length is 24.4 cm, the number of effective ears is 144000, the average total grains per ear is 221.2, the seed setting rate is 84.7%, and the 1000 grain weight is 26.7 g. The head rice rate is 61.5%, the chalkiness is 2.0%, the amylose content is 15.3%, the gel consistency is 60 mm, the alkali dissipation value is 6, and the length width ratio is 3.6, reaching the second level of the standard of the agricultural industry "Quality of Edible Rice Varieties".

★ Adaptability
Yield performance: participated in the regional test of medium indica late maturing group in the middle and lower reaches of the Yangtze River in 2017, with an average yield of 636.78 kg per mu, 3.56% more than the control Fengliangyou No. 4; In 2018, the average yield per mu was 692.88 kg, 3.60% more than that of CK Feng Liang You No. 4; The average yield per mu in two years' regional trials was 664.83 kg, 3.58% higher than that of the control Fengliangyou No. 4; In the 2019 production test, the average yield per mu was 645.45 kg, 3.39% more than that of the control Fengliangyou No. 4.
Resistance: the comprehensive indexes of rice blast in two years were 5.1 and 4.7 respectively, and the loss rate of ear neck blast was the highest level of 7. It was susceptible to rice blast, highly susceptible to bacterial blight, and had strong heat resistance at heading stage.

★ Main cultivation measures
1. Sow at the right time and plant strong seedlings sparsely. In the middle and lower reaches of the Yangtze River, medium rice should be planted in the early and middle April. The seed consumption per mu for seedling raising and transplanting is 1.0-1.2 kg, that for direct seeding and throwing is 1.5-2.0 kg, and that for field seedling raising and transplanting is 0.75-1 kg. The seeds should be soaked and disinfected with strong chlorine, the management of fertilizer and water during seedling stage should be strengthened, and the rice planthopper should be well controlled.
2. Planting early in time to promote tillering. Transplantation of water raised seedlings at 5-6 leaf stage, with seedling age of 25-30 days; Dry raised seedlings were transplanted at 3.5-4 leaf stage, and the seedling age was 15-18 days. Distance between plants and lines: 20cm × 30 cm, 2-3 grain seedlings per hole, 70000-80000 basic seedlings per mu.
3. Reasonable fertilization: apply 35-40 kg of high concentration compound fertilizer or 45-50 kg of common compound fertilizer per mu; Early application of tillering fertilizer: 8-10 kg urea per mu 5-7 days after planting, 8-10 kg potassium chloride per mu 20-22 days after planting. Increasing potassium fertilizer for ear grain fertilizer: 12-15kg potassium chloride per mu is applied in the middle booting stage to promote large ears, multiple grains and strong seeds, and nitrogen fertilizer is controlled in the middle and late stages.
4. Scientific water management and pest control. It turns green in inch water, tillers in shallow water and wet water, enough for seedlings to dry in the field, keeps shallow water at booting and heading stage, fills in dry and wet alternately, and drains water 6-8 days before harvest. Timely control rice blast, bacterial leaf blight, rice planthopper, rice leaf roller, sheath blight, rice false smut and other diseases and pests.

★ Suitable planting area
It is suitable for planting one season of medium rice in Hubei (except Wuling Mountain Area), Hunan (except Wuling Mountain Area), Jiangxi, Anhui, Jiangsu, Zhejiang, northern Fujian, southern Henan and other areas with low incidence of rice blast. It is not suitable to plant in areas with severe 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.
