Output performance:

In 2002, he participated in the regional test of the middle indica rice late maturing group in the upper reaches of the Yangtze River. The average yield per mu was 561.49 kg, 3.73% higher than the control Shanyou 63 (extremely significant); In 2003, the average yield per mu was 603.56 kg, 4.74% higher than the control Shanyou 63 (extremely significant); The average yield per mu in the two year regional test was 583.84 kg, 4.28% higher than that of the control Shanyou 63. In the production test in 2003, the average yield per mu was 559.87 kg, 2.86% more than the control Shanyou 63.

Key points of cultivation technology:

1. Cultivate strong seedlings: according to the local planting habits, the seedlings are sown at the same time as Shanyou 63, and the seedling age is about 45 days;


2. Transplanting: 100000 to 120000 basic seedlings per mu;


3. Fertilizer and water management: focus on the bottom and pursue early, increase the application of organic fertilizer and phosphorus and potassium fertilizer, and control nitrogen fertilizer in the middle and late stages. Shallow water irrigation, suitable time for sun drying;

4. Control of diseases and pests: pay attention to the control of rice blast and bacterial leaf blight.
