Fuyou No.1 (Rice)

"Fuyou 1" is a new super-high-yield hybrid rice combination bred by high and new technology, which has passed the national examination and approval (Middle and Upper reaches of the Yangtze River Group) in 2003. In the national regional test in 2001, the average yield per mu was 612.5 kg, ranking second. In 2002, the trial was continued, with an average yield of 597 kg per mu, ranking first, with an average increase of 7.04% over the control in two years. In 2003, it entered the national regional trial of the middle and lower reaches of the Yangtze River and Wuling Mountain area. In the past two years, the yield per mu was 600,800 kg, which was more than 10,000 mu compared with the control in Hunan, Sichuan, Guangdong, Guangxi, Hubei, Guizhou and Shaanxi. The highest yield per mu was 857 kg of Jiangyang District, Luzhou City, Sichuan Province. Wuma Town, Renhuai City, Guizhou Province planted "Fuyou 63" 5 days later, plant height 118 cm, ear length 24 cm, ear setting rate 168, seed setting rate 85%, 1000-grain weight 28 grams. The plant type is compact, the tillering ability is strong, the leaf is dark green, the root system is developed, the stem is strong, the heading is neat, the effective panicle is many, the resistance is good, the suitability is strong, and the rice quality is medium.

The super high yield cultivation techniques of "Fuyou 1" are as follows:

1. Sow early at the right time and raise seedlings in two stages. All localities can sow seeds before the Qingming Festival as far as possible according to the local altitude, air temperature and water source conditions, and carry out two-stage transplanting and raising seedlings, strong seedlings and multi-branched seedlings.

2. Apply sufficient base fertilizer to level the paddy field. Generally, 1000-1500 kg of farm manure and 50 kg of compound fertilizer should be applied per mu, and the land should be finely leveled at the same time.

3. Increase the planting density and insert the basic seedlings. It can appropriately increase the planting density by 1015% compared with the local varieties, and ensure that the basic seedlings are not less than 8 ~ 100000.

4. Pay attention to the coordination of nitrogen, phosphorus and potassium fertilizers and apply balanced fertilizer.

5. pay attention to the prevention and control of diseases and insect pests. Before moving the seedlings into the field, first control diseases and insect pests, and then observe and understand the disease index at any time, timely spraying pesticides.
