Long-term selection 14 new rice varieties is Changchun City Academy of Agricultural Sciences Jinfeng as female parent, long selection No. 2 as the father of artificial hybrid selection. In 2004, it was approved by the Jilin Provincial Crop Variety Approval Committee. Validation (Registration) No.: Jisong Rice 2004014. In 2012, it was awarded the Changchun Municipal Government's Advanced Agricultural Technology Promotion Award.
I. Variety characteristics
1. Botany traits: seed shape, oval rice grain, Ying and Ying Huang, no awns, grain weight 24 grams. Plant traits: Plant height 105 cm, thick stalk toughness, compact plant type, flag leaves on the move, dark green stems and leaves, strong tillering force, a single transplanting effective spikes per hole about 22. Spike shape: Spike length 19 cm, no awns, long grain shape, curved scattered ear type, the main panicles and ears are neat, the number of grains per panicle is 140, the average number of grains per panicle is 110, the grain density is moderate, the seed setting rate is 90%; Cold-resistance, fertilizer-resistance, salt-alkali-resistance, light frost resistance, lodging resistance, live stalk maturity.
2. Rice quality analysis: According to the NY/T593-2002 "quality of edible rice varieties" standard, the rice rate was 83.0%, the polished rice rate was 76.2%, the whole polished rice rate was 74.0%, the grain length was 5.0 meters, the aspect ratio 1.8, chalkiness rate 10%, chalkiness 1.0, transparency grade 1, alkali elimination value 7.0, gel consistency 72 mm, direct starch content 16.6%, protein content 6.7%. The rice rate is high, rice is soft, and the quality of rice is high-quality rice.
3. Stress resistance: Artificial seeding of seedlings at the seedling stage for three consecutive years, inducing seedlings, leafhoppers, and stems and stems in the middle of the seedling stage; spontaneous identification of many different sites in the adult diseased area, resistance to seedlings, leafhoppers, susceptibility Stem pods.
4. Fertility days: Late-maturing varieties. The growth period is 140 days, and the accumulated temperature should be ≥10°C 2800-2900°C.
5. Production performance: From 2002 to 2003, Jilin Province, the average yield of 551.1 kilograms of regional tests, the average yield of 547.5 kilograms per mu, after three consecutive years of 2009-2011 in a large area of ​​different ecological regions test demonstration, the average yield of 670-715 kilograms per mu.
Second, cultivation points
1. Seeding and Transplanting: Planting in mid-April, dilute seeding and breeding, 150 grams per square meter. In the middle and late of May, when the average temperature is stable above 13°C, it can be planted with a density of 96 (inches) or 98 (inches). Put -3 strains. Throwing: throwing density 20-25 points / square meter.
2. Fertilization: Under general soil conditions, hectares use 160 kg of pure nitrogen, 75 kg of pure phosphorus as the base fertilizer, and 100 kg of pure potassium, of which 70% of base fertilizer and 30% of panicle fertilizer. Nitrogen, phosphorus, and potassium are combined with fertilization, combined with the application of zinc, silicon, magnesium, sulfur, boron and other micronutrients. According to the base fertilizer, tiller fertilizer, supplementary fertilizer, panicle fertilizer 4:3:2:1 ratio is applied in stages.
3. Field Management: Science Irrigation. Water-saving irrigation techniques should be adopted, and light-deep-shallow alternate dry and wet irrigation methods should be adopted. When transplanting rice field, “flowers reach the waterâ€, after transplanting, keep the water layer 3.0 centimeters, and return to the shallow water for irrigation. The effective tillering period—the spike differentiation period should maintain 6.0 centimeters of water layer. After this period, it still maintains 3.0 centimeters of water layer. When the soil is fertile and the reduction is strong, the field should be sun dried to reduce ineffective tillers and increase the number of effective tillers. The water requirement for the booting and emergence of flowers at the flowering stage should be large. In order to ensure sufficient water for the spikes and grains, the field water layer should be maintained at 6.0 cm. After this period, the shallow water layer will be restored. After the milk ripening period, dry and wet and wet alternate irrigation should be performed. If water cannot be cut off prematurely, otherwise the yield and quality will be reduced. Drainage should be stopped 10-15 days before harvest.
Three, pests and weed control
1. Weeding in paddy fields: 7 days after transplanting, the water was used for keeping water for 7 days. With 60% butachlor EC 10 ml plus 10% Agricultural powder 20 grams of herbicide diluted 20 kg evenly sprayed.
2. Insect pest control: control of rice water weevil, in early June with 1.0% matrine aqueous solution 1200 ml / ha, sprayed on the water; prevention and control of larvae worms: July 10 rice stem borer spawning period, with "Triazophos" prevention and control, can also be used 5.0% insecticidal double water 3000 ml / ha, spraying water.
3. Disease prevention and control: control of rice blast, seedling emergence and heading, full heading can be used 40.0% Fuji No. 1 900-1500 ml / ha, spraying or 2.0% chitosan EC 500-1000 times spray control; Rhizoctonia solani: use 5.0% Jinggangmycin water solution 700-1000 times liquid to control Sheath blight; prevent rice false smut: rice smut is a flower organ dip, should be 5-7 days before the flowering of rice ear, with 14.0% "Ammonia copper" water 3750-5250 ml / ha, spraying water.
Fourth, suitable area
Suitable for planting in Changchun, Siping, Baicheng, Songyuan, Jilin and other mid-and late-maturing rice regions in Jilin Province.
