High quality, high yield and high benefit

★ 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 one crop of medium rice is 135.8 days, 2.4 days earlier than the control Fengliangyou No. 4. The plant height is 119.9 cm, the spike length is 25.0 cm, the effective spikes per mu are 142000, the total grains per spike are 223.8, the seed setting rate is 82.3%, and the 1000 grain weight is 28.3 g. Main indicators of rice quality: head rice rate 61%%, chalky grain rate 12%, chalkiness 2.8%, amylose content 13.9%, gel consistency 78 mm, length width ratio 3.2, reaching the second level of the standard of "Quality of Edible Rice Varieties" in the agricultural industry.

★ Adaptability
Yield performance: participated in the regional test of late maturing group of medium indica rice in the middle and lower reaches of the Yangtze River in 2015, with an average yield of 704.57 kg per mu, 5.19% more than that of the check Fengliangyou No. 4; In 2016, the average yield per mu was 625.87 kg, 3.69% more than that of CK Fengliangyou No. 4; The average yield per mu in two years' regional trials was 665.22 kg, 4.44% higher than that of the control Fengliangyou No. 4; In the production test in 2017, the average yield per mu was 632.87 kg, 2.46% more than that of CK Fengliangyou No. 4.
Resistance: the comprehensive indexes of rice blast in two years were 5.7 and 4.4 respectively, and the loss rate of ear neck blast was the highest level of 7. It was susceptible to rice blast, moderately susceptible to bacterial blight, and had strong heat resistance at heading stage.

★ Main cultivation measures
1. Cultivate seedlings by precise sowing. In the first and middle of April, the medium rice should be sown with a seed consumption per mu of 1.0~1.2kg. It must be thinly sown and evenly sown. After drying the water in the seedling field at the stage of one leaf and one heart, 15% paclobutrazol 80~100g should be sprayed per mu to promote the seedling growth and tillering, and strengthen the management of fertilizer and water in the seedling field.
2. Planting early in time to promote tillering. Transplanting in 5-6 leaf stage of water raised seedlings, 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. Line spacing: 23cm × 26.6cm, 2 grain rice seedlings per hole, 70000-90000 basic seedlings per mu.
3. High fertilizer management to increase phosphorus and potassium. Heavy application of base fertilizer: 30~35kg of high concentration compound fertilizer or 45~50kg of common compound fertilizer per mu; Tiller fertilizer was applied twice: 7-8 kg urea and 5-6 kg potassium chloride were applied every mu 5-7 days after planting; Apply 4-5kg urea and 6-7kg potassium chloride per mu 16~18 days after planting according to seedling conditions. Skillful application of panicle and grain fertilizer: at the early booting stage, the irrigation shall be completed in combination with the sun drying field, and 10~15kg of high concentration compound fertilizer and 10~12kg of potassium chloride shall be applied per mu according to the field appearance to promote large panicles, multiple grains and strong seeds.
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. Timely control rice blast, rice false smut, rice planthopper, rice leaf roller, sheath blight, etc. Special attention shall be paid to the control of rice blast.

★ Suitable planting area
It is suitable to plant one season of medium rice in Hubei (except Wuling Mountain Area), Hunan (except Wuling Mountain Area), Jiangxi, Anhui and Jiangsu provinces in the Yangtze River valley rice region, as well as in Zhejiang, northern Fujian and southern Henan rice regions with low incidence of rice blast. It is not suitable to plant in areas with high incidence of rice blast.

★ Planting season
In the middle and lower reaches of the Yangtze River, it is suggested to sow rice from April 1 to May 31.
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.
