Approval number: Sushendao 20200027

Variety name: Ningxiangjing No. 9

Applicant: Rice Research Institute of Nanjing Agricultural University

Breeder: Rice Research Institute of Nanjing Agricultural University

Variety source: Ningjing 1 / Wu Ruan // Ningjing 3, the name of the test was "Ningjing 09"

Characteristics: It is an early-maturing late japonica rice variety. The seedlings are short and sturdy, the leaf color is medium green, the tillering power is medium to high, the plant type is compact, the plant height is moderate, the stalk is thick, and the lodging resistance is good. The population has good uniformity, the ear layer is neat, the ear shape is large, the leaves are tall, the color is good in the later stage, and the stalks are green and the seeds are yellow. The average results of the provincial and regional tests: the whole growth period was 5. days, which was shorter than the control Changnongjing No. 8 by days. The plant height is 9.cm, the effective ears per mu is 20,000, the total number of grains per ear is 4, the seed setting rate is 0.9%, and the 1,000-grain weight is 2.g. Appraised by the Plant Protection Institute of Jiangsu Academy of Agricultural Sciences: panicle neck blast loss rate, rice blast comprehensive resistance index., moderately susceptible to rice blast, bacterial blight, stripe blight, and susceptible to sheath blight. The physical and chemical indicators of rice quality are tested by the Food Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture and Rural Affairs (Wuhan) for 21 years: the whole rice rate is 7.%, the chalky grain rate is 2.%, the chalkiness is .%, the gel consistency is 8 mm, and amylose The content is 1.%, the aspect ratio is. It is a soft rice variety.

Yield performance: Participated in the early-maturing early-maturing late japonica rice regional test in Jiangsu Province from 21 to 2009. The average yield per mu in two years was 9. kg, which was an increase of% compared to the control Changnongjing. Participated in the production test in 21 years, the average yield is 70.0 kg per mu, which is 4.4% higher than the control Changnongjing No. 8.

The key points of cultivation techniques: 1. Sowing seeds at an appropriate time and cultivating strong seedlings. Generally sowing in mid-to-late May (machine-transplanted seedlings in late May), moist seedlings, the sowing amount per mu of seedling field is about 5~3 kg, dry seedlings are about 3-0 kg, and machine-transplanted seedlings are about 3~4 kg per mu of field. Sowing evenly to cultivate strong seedlings of appropriate age. 2. Transplant timely and plant closely. Generally transplanted in mid-to-late June, the seedling age is about 3 days (machine-transplanted seedlings for 1 to 0 days), transplanted in time, planted enough holes per acre, and basic seedlings per acre of 60,000 to 10,000. 3. Scientific fertilizer and water management. The amount of pure nitrogen applied in a large area is about 8 kg per mu. The fertilizer management adopts the fertilization principle of "pre-weight, mid-control, and post-replenishment", and attaches importance to the combined application of phosphorus and potassium fertilizers and organic fertilizers. In water slurry management, pay attention to shallow hydroponic planting, live trees with a inch of water, and tiller with thin water. When each mu of stems and tillers reach enough ears, the fields should be set aside in time, and the field will be dry and wet alternately at the later stage of growth. When it gets old, there will be no water a week before harvesting. ,Pest Control. Before sowing, soak seeds with medicament to control bakanae disease and stem worm disease. During the seedling stage, focus on the prevention and control of rice thrips and Laodelphax striatellus. In the field, the focus will be on the prevention and control of Chilo suppressalis, Chilo suppressalis, rice leaf roller, rice planthopper and other pests. Comprehensive prevention and control of rice blast and rice smut during the oral period.

Approval opinion: Approved and suitable for planting along the Yangtze River and southern Jiangsu Province.
