★ Characteristics
Indica two-line hybrid rice
The pioneer combination of the third phase of super hybrid rice, which was developed by using innovative technology for indica japonica polymerization hybridization, has moderate plant type, good luxuriance, strong tillering ability, medium thick stalks, colorless leaf sheaths and lemma tips. The results of provincial and regional trials: the plant height is 110.4 cm, the effective panicles per mu are 170000 to 180000, the total grains per panicle are 163.4, the seed setting rate is 87.8%, and the 1000 grain weight is 27.5 g. Resistance: the average leaf blast level is 1, the average ear blast level is 9, the comprehensive resistance index of rice blast is 5.2, and the cold resistance and high temperature resistance are strong. Rice quality: brown rice rate 80.4%, milled rice rate 72.6%, head rice rate 58.3%, grain length 6.9 mm, length width ratio 3.3, chalkiness grain rate 24%, chalkiness 4.6%, transparency 1, alkali dissipation value 6.4, gel consistency 81 mm, amylose content 13.1%, protein content 8.6%.


★ Output performance
In 2012, it participated in the joint product comparison test at 8 test sites in Hubei, Anhui, Hunan and other provinces' medium rice regions, with an average yield of 722.5 kg per mu, which was 12.5% higher than the control IIyou 838, reaching a very significant level. In 2012, Hunan Hongjiang demonstrated a 100 mu high yield project. Under the fine management of high fertilizer and water, the average yield per mu was 835.5 kg/mu, and the maximum yield per mu in hilly areas exceeded 900 kg. The fields grew luxuriantly, with light pests and diseases, and good ripening and fading.


★ High quality and super high yield cultivation techniques
1. Cultivate seedlings by precise sowing. Sowing in the middle and late April as medium rice and in the middle and late May as a season of late rice. The seed consumption per mu is 0.8-1.0 kg. It must be thinly sown and evenly sown. After paclobutrazol is used to treat the sprout grain or the seedling with one leaf and one heart period and the water in the seedling field is dried, 15% paclobutrazol 80-100 g/mu is sprayed with 30 kg water to promote the seedling growth and low tillering, and strengthen the management of fertilizer and water in the seedling field.
2. Early planting at the right time promotes tillering. The seedlings were transplanted at 5-6 leaf stage, and the seedling age was 25-30 days; Dry raised seedlings are transplanted at 3.5-4 leaf stage, and the seedling age is 15-18 days. Line spacing 7 × 8 inch or 6 × 9 inches, 2 rice seedlings per hole.
3. High fertilizer management will lead to high yield. ① Heavy application of base fertilizer: 35-40 kg of high concentration compound fertilizer or 50-60 kg of common compound fertilizer per mu; ② The tillering fertilizer was applied twice: 7-8 kg urea and 6-7 kg potassium chloride per mu 5-7 days after planting; 16-18 days after planting, 5-7 kg urea and 7-8 kg potassium chloride shall be applied per mu according to seedling conditions.
4. Heavy application of ear fertilizer to promote large ears: at the early stage of booting, irrigation should be completed in combination with sun drying. According to the appearance of the field, 12-20 kg of high concentration compound fertilizer and 12-15 kg of potassium chloride should be applied per mu to promote large ears, multiple grains, strong stems and strong seeds.
5. Scientifically manage water to prevent diseases and pests. The water turns green. The tiller is wet in shallow water, which is enough for seedlings to dry the field. There is water for booting and heading. The strong seeds are wet, and the water is drained 6-8 days before harvest. It is suitable for planting in areas with low incidence of rice blast. In hilly and mountainous areas, attention should be paid to the prevention of early seedling and leaf blast and the application of 75% tricyclazole+imported Fuji No.1 at the break heading stage to prevent ear neck blast, and the timely prevention of rice planthopper, rice leaf roller, sheath blight, etc.
