How to apply phosphorus and potassium fertilizer in corn planting?
How to apply phosphate fertilizer and potassium fertilizer in corn planting? Please give guidance on the application effect of phosphorus and potassium fertilizer in planting corn due to the great difference in soil available content. The application of phosphorus and potassium is beneficial to strong seedlings and large ears, increase the ratio of grains to leaves, increase the number of grains and grain weight, which is an important condition to improve population quality. However, after the application of phosphorus and potassium fertilizer, most of it is absorbed and fixed by the soil, the absorption and utilization rate of phosphorus and potassium fertilizer is low in that season, the mobility in the soil is poor, and its fertilizer effect is not easy to be lost, and its fertilizer effect is as long as several years. Therefore, in order to improve the absorption and utilization of phosphorus and potassium fertilizer in the current season, one application should be used as a base fertilizer in the sowing line, which is the best, which is beneficial to the absorption and utilization of corn and promote the formation of high yield. Studies have proved that the application of phosphate fertilizer in sowing period increased the yield by 8.5%, 13.7% and 14.8%, respectively, compared with 3-leaf, 6-leaf and 9-leaf development, while the application of potash fertilizer increased 2.1%, 5.1% and 11.6%, respectively, compared with 3-leaf, 6-leaf and 9-leaf application.
