The plant type is compact, the plant height is moderate, the stem toughness is good, the tillering force is strong, the foot leaves at the base are more, and the growth potential is strong. The blade is green, the sword leaf is medium long and straight, and the leaf is under the grass. The panicle layer is regular, the panicle type is medium, the panicle neck node is short, and the grains are uniform. The grain is long, with purple lemma tip and short awn on some grains. The late maturity is better. In the regional test, 224000 effective ears per mu, 99.8cm plant height, 21.7cm ear length, 130.3 grains per ear, 106.3 grains per ear, 81.6% seed setting rate, and 25.74g 1000 grain weight. The whole growth period is 118.0 days, 0.9 days longer than Jinyou 207. From 2013 to 2014, he participated in the regional test of late rice varieties in Hubei Province. The rice quality was determined by the Food Quality Supervision, Inspection and Testing Center (Wuhan) of the Ministry of Agriculture. The rice yield was 82.3%, the head rice rate was 62.8%, the chalky grain rate was 23%, the chalkiness was 5.6%, the amylose content was 24.7%, the gel consistency was 30 mm, and the length width ratio was 3.4.
product details
It is a late indica rice variety with medium maturity and late maturity.
The plant type is compact, the plant height is moderate, the stem toughness is good, the tillering force is strong, the foot leaves at the base are more, and the growth potential is strong. The blade is green, the sword leaf is medium long and straight, and the leaf is under the grass. The panicle layer is regular, the panicle type is medium, the panicle neck node is short, and the grains are uniform. The grain is long, with purple lemma tip and short awn on some grains. The late maturity is better. In the regional test, 224000 effective ears per mu, 99.8cm plant height, 21.7cm ear length, 130.3 grains per ear, 106.3 grains per ear, 81.6% seed setting rate, and 25.74g 1000 grain weight. The whole growth period is 118.0 days, 0.9 days longer than Jinyou 207. From 2013 to 2014, he participated in the regional test of late rice varieties in Hubei Province. The rice quality was determined by the Food Quality Supervision, Inspection and Testing Center (Wuhan) of the Ministry of Agriculture. The rice yield was 82.3%, the head rice rate was 62.8%, the chalky grain rate was 23%, the chalkiness was 5.6%, the amylose content was 24.7%, the gel consistency was 30 mm, and the length width ratio was 3.4.
★ Adaptability
Yield performance: The average yield of late rice in Hubei Province in the regional trials from 2013 to 2014 was 557.21kg/mu, which was 7.09% higher than that of Jinyou 207. In 2013, the yield per mu was 531.47 kg, 7.58% higher than that of Jinyou 207; In 2014, the yield per mu was 582.94kg, 6.64% more than that of Jinyou 207.
Resistance: the disease was identified as the comprehensive index of rice blast 5.9, the highest loss rate of rice blast was 9 grades, and the disease was highly susceptible to rice blast; Grade 7 bacterial leaf blight, susceptible to bacterial leaf blight.
★ Main cultivation measures
1. Sow thinly at appropriate time to cultivate strong seedlings. Sowing from June 17 to 20, the seeding amount per mu of seedling field is 7~8 kg, and the seed amount per mu of field field is 1.25~1.5 kg. Soak the seeds with prochloraz before sowing. Apply 3~4 kg urea 4~5 days before transplanting.
2. Planting early in time to promote tillering. The seedling age shall not exceed 28 days. Row spacing 16.7cm × 23.3 cm, 2-3 grain seedlings per hole, 80000-90000 basic seedlings per mu.
3. Scientific management of fertilizer and water. Generally, 10 kg of pure nitrogen, 6 kg of phosphorus pentoxide and 8 kg of potassium oxide are applied per mu. The base fertilizer is generally 25 kg per mu of Hefei, and 6-8 kg of urea and 7-8 kg of potassium chloride are applied 5-7 days after transplanting. Ear and grain fertilizers are added to the seedlings. It turns green in inch water, tillers in shallow water, enough for seedlings to dry in the field, maintains a shallow water layer from booting to heading, alternates dry and wet in the later stage, and water is cut off 6 to 8 days before harvest.
4. Disease and pest control. Pay attention to the prevention and control of rice blast, rice false smut, sheath blight, bacterial leaf blight, borers, rice planthoppers and other diseases and pests.
★ Suitable planting area
It is suitable for late rice planting in Jianghan Plain of Hubei Province and southeast Hubei Province, but it is not suitable for rice blast frequent and severe areas.
★ Planting season
It is recommended to sow from June 15 to June 22.
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.
