Characteristics: Indica two-line hybrid rice variety. Planting mid-season rice in the middle and lower reaches of the Yangtze River has a full growth period of 133.9 days, 1.8 days shorter than the control Fengliangyou No.4. The plant height is 113.8 cm, the ear length is 25.5 cm, the effective ear number per mu is 151,000 ears, the total number of grains per ear is 210.2, the seed setting rate is 81.7%, and the thousand-grain weight is 25.3 grams. Resistance: The comprehensive index of rice blast was 6.1 and 6.2 in two years, the highest loss rate of ear neck blast was 9 grade, Bacterial blight was grade 5, brown planthopper was grade 9, and the heading stage heat resistance was grade 1; high susceptibility to rice blast, medium It is susceptible to bacterial leaf blight, highly susceptible to brown planthopper, and has strong heat tolerance at heading stage. Main indicators of rice quality: whole rice rate 65.9%, chalky grain rate 11%, chalkiness 1.9%, amylose content 13.3%, gel consistency 73.3 mm, length-to-width ratio 3.2, reaching the agricultural industry "Edible Rice Variety Quality" Standard level three.

 

Yield performance: Participated in the regional test of the late-maturity group of mid-indica in the middle and lower reaches of the Yangtze River in 2016, with an average yield of 626.6 kg per mu, which is 6.4% higher than the control Fengliangyou No. 4; continued in 2017, with an average yield of 633.2 kg per mu, which is better than the control Fengliang The yield of No. 4 increased by 8.5%; the average yield per mu in the two-year regional test was 629.9 kg, which was 7.5% higher than the control Fengliangyou No. 4; the production test in 2018 showed an average yield of 615.6 kg per mu, which was 3.6% higher than the control Fengliangyou No. 4.

 

Key points of cultivation techniques: 1. Raising seedlings. Sowing seedlings at the right time, dry seedlings or moist seedlings, cultivate more tiller and strong seedlings. 2. Transplanting. Transplant at the right time, the age of the seedlings is 25-30 days, the planting specifications of the middle and upper fertility fields are 16.7 cm × 26.7 cm, and the medium and lower fertility fields should be appropriately increased in density. 3. Fertilizer and water management. The total amount of fertilizer required per mu of field is 14-18 kilograms of pure nitrogen, 40-50 kilograms of phosphate fertilizer, and 15 kilograms of potassium fertilizer. 60% of the total amount is used as base fertilizer. After transplanting live trees, topdressing 5-8 kilograms of urea per mu can promote tillering. From booting to breaking stage, 3 to 5 kilograms of urea per mu is topdressed as ear-grain fertilizer. The irrigation method of "planting seedlings in shallow water, living trees in inch of water, thin-water tillers, deep-water heading, and dry and wet in the later stage" is adopted. When the number of seedlings per mu reaches 180,000, the fields are drained and dried in time to control the seedlings. 4. Comprehensive control of diseases and insect pests, insist on soaking seeds with strong chlorine essence before sowing, pay attention to applying pesticides to control rice planthoppers during the seedling period to prevent southern black-streaked dwarf disease; , Rice blast, bacterial leaf blight, rice planthopper, stem borer and other pests, pay special attention to the prevention and control of rice blast.
