Parameters

Variety type: Japonica conventional rice

Approval number: Su Shendao 201111

Characteristics: moderate plant type, vigorous growth, strong tillering ability, large ear shape, easy threshing, moderate lodging resistance. The effective ears per mu are 223,000, the number of seeds per ear is 116.9, the seed setting rate is 90.2%, the thousand-grain weight is 26.7 grams, the plant height is 100.3 cm, and the whole growth period is 153 days.

Resistance performance: moderately susceptible to bacterial leaf blight, sheath blight, and stripe leaf blight.

Quality performance: According to the inspection of the Food Quality Inspection Center of the Ministry of Agriculture, the rice quality has reached the national standard for second-level high-quality rice.

Yield performance: Participated in the regional test of Jiangsu Province from 2008 to 2009. The average yield per mu in two years was 605.4 kg, which was an increase of 1.88% compared with the control Huaidao No. 9. The increase in production in 2009 was extremely significant; the average yield per mu in the production test in 2010 was 606.7 kg, which was an increase in yield compared with the control. 5.4%.

Adaptation range: Suitable for planting in the Yang hilly area of Suzhong and Ningzhen, Jiangsu Province.

Cultivation technology points:

1. Sow seeds at an appropriate time and cultivate strong seedlings. Generally, the planting is in mid-May. The sowing rate of wet seedlings is 25-30 kg per mu of net seedling board, the sowing rate of dry seedlings is about 40 kg per mu of net seedling board, and the seeding rate is 3-4 kg per mu of field.

2. Transplant at the right time and plant closely. Generally transplanted in mid-June, seedling age is 30-35 days, 18,000-20,000 holes are planted per acre, and basic seedlings are 60,000-80,000 per acre.

3. Scientific fertilizer and water management. Apply 18-20 kg of pure nitrogen per mu, pay attention to the combined application of phosphorus and potassium fertilizers, and grasp the principle of "promoting, controlling and supplementing afterwards" in nitrogen fertilizer management. Seedlings are supplemented with ear fertilizer, and the ratio of base tiller fertilizer to ear fertilizer is 6:4. In terms of water slurry management, we need to master deep-water live trees, early shallow-water irrigation to promote early initiation, moderate field placement, peak seedlings controlled at about 300,000 per mu, dry and wet alternate later, and water cut off a week before maturity.

4. Prevention and treatment of diseases, pests and weeds. Before sowing, soak seeds with chemicals to prevent seed-borne diseases such as bakanae disease and dry tip nematode disease. Pay attention to the prevention and control of Laodelphax striatellus and rice thrips in the seedling and field stages. In the middle and late stages, comprehensive control of sheath blight, stem borers, and rice worms should be implemented. For leaf rollers, rice planthoppers, etc., attention should be paid to the prevention and treatment of panicle-neck rice blast and bacterial blight.
