Main indicators of rice quality: head rice rate 64.6%, aspect ratio 1.8, gel consistency 100 mm, amylose content 1.59%.

Yield performance: in 2001, in the upland rice regional trial of middle and late maturity groups in Huang-Huai-Hai wheat stubble area, the average yield per mu was 271.5 kg, 8.4% higher than that of Zhengzhou early japonica, and in 2002, the average yield per mu was 269.6 kg, 5.8% higher than that of Zhengzhou early japonica. In the production experiment in 2003, the average yield per mu was 300.4 kg, which was higher than that of Zhengzhou early japonica and upland rice.

Main points of cultivation techniques: 1, seed treatment: drying before sowing, coating with seed coating agent; 2, sowing: leveling the land before sowing, applying farm manure 1000 kg per mu, fertilizer diammonium phosphate 10 kg, potassium sulfate 10 kg, ammonium sulfate 15 kg. Both strip sowing and hole sowing are possible, and the sowing rate is 8-9 kg per mu. Row spacing 30 cm, sowing depth 2-3 cm, suppressed or stepped on the grid after sowing; 3, chemical weeding: Quick-killing paspalum, 60% butachlor 0.25 kg per mu, Nongsi 0.25 kg, mixed with water spray; 4. Field management: timely irrigation in case of drought during emergence, tillering, booting and filling period, and applying about 10 kg ammonium sulfate at jointing, booting to heading stage depending on seedling condition. 5. control of diseases and insect pests: pay attention to the prevention and control of rice false smut.

Approval opinion: after examination, the variety conforms to the national rice variety approval standard and has been approved. The variety has strong drought resistance, moderate maturity, high yield, good yield stability, medium resistance to rice blast and flax leaf spot, and good waxy. It is suitable for dry cultivation of wheat stubble or rape stubble in Huanghuai area of Henan, Shandong, Anhui, Jiangsu (except Xuzhou area) and southern Shaanxi.
