Yield performance: in 2007, the average yield per mu was 70 1 .8kg, which was significantly higher than that of the control Zhu Jin 1.3%. In 2008, the average yield per mu was 734.3 kg, which was 2 1 .9% higher than Zhaojinzhu1(extremely significant). The average yield per mu in two-year regional trials was 7 18. 1 kg, which was 7.7% higher than that of Zhaojinzhu 1 yield increase 17.7%, and the proportion of yield increase points reached 92.9%. In 2008, the average yield per mu was 695 kg, which was 6.7% higher than that of Zhaojinzhu 1.
Key points of cultivation techniques: 1. Seedling raising: Sow with Zhu Jin 1 according to local production conditions in southern Liaoning and Beijing and Tianjin, and do a good job of drying and disinfection before sowing to prevent nematodes and bakanae diseases. The amount of seeds used in seedling field is about 1/2 of that of conventional varieties, and strong seedlings with tillers are cultivated. 2. Transplanting: about 35 days after transplanting, the row spacing is 30 cm×13.3 cm, with 2 plants per hole. 3. Fertilizer and water management: N, P, K and Zn fertilizers should be used together, and dry and wet alternation should be paid attention to to ensure that the effective panicle number per mu is about 6.5438+0.8 million. 4. Pest control: pay attention to the control of Chilo suppressalis, and other pest control is the same as general field production.
Examination and approval opinions: This variety meets the national rice variety examination and approval standards and has passed the examination and approval. This variety has moderate maturity, high yield, moderate rice blast resistance and average rice quality. Suitable for planting in southern Liaoning Province, southern Xinjiang, Beijing and Tianjin.

Yield performance: in 2006, he participated in the regional test of mid-late mature upland rice varieties in Huang-Huai-Hai wheat stubble rice area, with an average yield of 3 12.5 kg per mu, which was 8.5% higher than that of the control upland rice 277 (extremely significant); In 2007, the average yield per mu was 326.9 kg, which was 15.7% higher than that of the control upland rice 277 (extremely significant). The average yield per mu in the two-year regional trials was 3 19.7 kg, which was higher than that of the control upland rice 277 by 12. 1%, and the ratio of yield increase points was 8 1%. In the production test in 2008, the average yield per mu was 350.8 kg, which was 12% higher than that of the control upland rice 277.
Key points of cultivation techniques: 1. Sowing: Sowing in Huanghuai area from late May to early June. Before sowing, seeds can be coated with toxic soil or sprayed to control underground pests. The row spacing of drilling is 25cm, the sowing amount is 5-7kg/mu, and the sowing depth is 2cm. 2. Weeding: Herbicides are used in dry fields to "seal the soil" before sowing or "treat the stems and leaves" at seedling stage, and then artificial weeding is carried out in time. 3. Fertilizer and water management: combined application of nitrogen, phosphorus, potassium fertilizer and total base fertilizer of silicon and zinc; After sufficient sowing, water should be supplemented as appropriate, and water should be supplemented in time in case of drought at booting and filling stages. 5. Pest control: pay attention to control rice leaf roller, rice planthopper and sheath blight before and after jointing and heading, and prevent false smut at heading stage.
Examination and approval opinions: This variety meets the national rice variety examination and approval standards and has passed the examination and approval. This variety has good yield, stable yield, moderate drought resistance, moderate rice blast resistance, strong lodging resistance and excellent rice quality. It is suitable for planting summer-sown upland rice in Henan, Jiangsu, Anhui, Huanghuai Valley in Shandong and Hanzhong rice area in Shaanxi. According to Announcement No.516 of the Ministry of Agriculture of People's Republic of China (PRC) (China), this variety (authorized number: Guoshen Rice 2005040) is also suitable for planting in southern Liaoning, southern Xinjiang, Beijing and Tianjin.
