Rice should be combined with nitrogen, phosphorus and potassium.
Rice needs to absorb a variety of elements throughout its life, and an appropriate ratio between the amounts of various elements is needed to coordinate growth. Insufficient element of any of nitrogen, phosphorus and potassium will lead to abnormal growth and development and reduced yield. According to the law of minimum nutrient, the element of this deficiency becomes a barrier factor in production and becomes the primary problem to be solved when fertilizing. In addition, nitrogen, phosphorus and potassium have their own elemental characteristics in rice plants and yield components. Rice also has biological characteristics for nitrogen, phosphorus and potassium utilization. Therefore, how to balance phosphorus, potassium fertilizer and nitrogen fertilizer is important for high yield of rice. A ring. When the application of nitrogen, phosphorus and potassium is well combined, they can promote each other; if the cooperation is not good, they will restrict each other.
In order to capture high yield of rice, it is necessary to increase the application of nitrogen fertilizer and increase the application of phosphate fertilizer and potassium fertilizer to fully meet the needs of rice for nitrogen, phosphorus and potassium fertilizer. At present, the amount of nitrogen fertilizer used in rice production tends to be excessive, while phosphorus and potassium fertilizers are often ignored. Because nitrogen fertilizer has a great influence on the yield composition, the response to plants is relatively intuitive, which is easy to attract people's attention, while phosphorus and potassium mainly rely on soil supply. Until recently, the effective phosphorus and potassium supply intensity of soil has been seriously reduced, which has become a production limiting factor. The high-yield cultivation, especially in the ultra-high-yield cultivation, has a prominent effect on the increase of phosphorus and potassium fertilizers. The ratio of nitrogen, phosphorus and potassium in rice application is generally 1:0.4-0.6:1-1.5. However, in practical applications, factors such as nitrogen, phosphorus and potassium in the soil and rice yield should be considered, and the proportion should be appropriately adjusted. If the soil in the paddy field is deficient in phosphorus, the application of phosphate fertilizer should be added; if the soil is deficient in potassium, the application of potassium fertilizer should be added. If the yield of paddy soil is often deficient in nitrogen and phosphorus, nitrogen and phosphate fertilizers should be added. In high-yield paddy fields, where potassium is often deficient in the soil, potash should be added.
