2 6 High quality
' Ningxia 4149' Rice has excellent quality, good taste, suitable for the public's taste, and high rice yield.
3 High-yield planting and cultivation technology
31 Sow seeds in time
'Yongyou 4149' is planted in the low-altitude areas of Shimen, and the seeds can be safely planted from the end of April to the beginning of May. Control the seedling age well, control the seedling age of water cultivation for about 25 days, and control the seedling age of machine transplanted seedlings within 20 days.
3 2 Reasonable and close planting
Choose different planting methods and determine the appropriate sowing volume. Live streaming: 18.75 kg of seedlings per hectare, 30.0 kg of seedlings were used for transplanting, and 15.0 kg of seedlings were used for transplanting. Reasonable and dense planting, the machine insertion density is 16 cm × 30 cm, and the seedling transplant density is 19.8 cm × 26.4 cm. The planting is about 19.5 million per hectare, ensuring 600,000 to 750,000 basic seedlings, ensuring the basic seedlings required for the target yield.
3-3 Fixed fertilizer application
0 Determine the fertilizer usage according to the target rice yield, soil fertilizer supply capacity and fertilizer nutrient utilization rate, and apply fertilizer in a balanced manner in the ratio of nitrogen:phosphorus:potassium = 1:0.5:0.8. Apply nitrogen, phosphorus and potassium to each hectare, each containing 900 kg of compound fertilizer, 255 kg of urinary, and 225 kg of potassium chloride, each containing 600 kg of compound fertilizer (base fertilizer), and apply 15 kg of zinc sulfate per hectare to each hectare. After transplanting, apply 75 kg of urin and 75 kg of 45% compound fertilizer per hectare, add 15 packets of herbicide and mix well and spread evenly, and retain water for about 5 days. After transplanting, 105 kg of urinate and 150 kg of 45% compound fertilizer were applied for about 15 days. After the fields were covered with water, 75 kg of urin, 225 kg of potassium fertilizer and 75 kg of compound fertilizer were applied per hectare. According to the principle of the secondary slurry of hybrid rice, fertilizer is applied during the jointing period, and sprayed particles to maintain the strong ears during the ear period to fully exert the potential of hybrid rice to increase the yield.
34 Scientific pipe water
is implemented according to the principles of inch water, shallow water tillering, water pumping, dry and wet pulping, old water not dry, fresh water not rising, good gas irrigation. By scientifically regulating water, increase the oxygen content of soil, increase soil temperature, and improve the soil environment for rice growth. When about 14 stems and till tillers per hectare, 2.1 million to 2.4 million seedlings are placed lightly at the beginning many times. If the nutrients and growth are too prosperous, ditches will be opened immediately to dry the fields.
3-5 Comprehensive prevention of disease insecticide damage

In particular, we must take good care of the second prevention and treatment. Chemical prevention and treatment should be careful to prevent the impact of large doses and high concentrations of pesticides on the fruiting rate of rice, and ensure safe growth and ecological friendliness.
