Output performance:

In 2001, he participated in the regional test of medium indica rice late maturing group in the upper reaches of the Yangtze River, with an average yield of 614.1 kg per mu, 5.4% more than the control Shanyou 63 (extremely significant); In 2002, the average yield per mu was 602.0 kg, 11.2% higher than the control Shanyou 63 (extremely significant). The production test in 2002 was 520.8 kg, 10.79% more than the control Shanyou 63.

Key points of cultivation technology:

1. Timely sowing: the sowing date is the same as Shanyou 63, and the seedling age is 35~45 days;


2. Reasonable dense planting: 80000-120000 basic seedlings per mu;


3. Reasonable fertilization: sufficient base fertilizer, early topdressing, combined application of nitrogen, phosphorus and potassium;

4. Prevention and control of diseases and pests: pay attention to the prevention and control of rice blast, bacterial leaf blight and other pests.
