Peanut planting technology: how does peanut absorb fertilizer?

How does peanut absorb fertilizer? Please introduce that peanut kernels are rich in protein and fat. To form these substances, you need a lot of nutrients. According to the research, pure nitrogen (N) 6.8kg, phosphorus (P2O5) 1.3kg and potassium (K2O) 3.8kg are needed for each production of 100kg peanut pods. Nitrogen is the most, potassium is the second, and phosphorus is the least. In addition, peanuts need more calcium. Peanuts, like soybeans, take root nodules and can fix nitrogen in the air. During the whole growth period, peanuts only need to absorb 1 of the total nitrogen from the soil to meet the needs of peanuts, and other nutrients need to be absorbed from the soil. Because peanuts have the characteristics of flowering above ground and podding underground, peanut roots not only absorb fertilizer, but also cone and young fruit can absorb fertilizer. Generally speaking, the fertilizer absorption characteristics of peanuts are more in the middle and less at both ends. At the seedling stage, due to slow growth and low absorption of nutrients, the absorption of nitrogen, phosphorus and potassium only accounts for about 5% of the total absorption during the whole growth period. Flowering is the period of rapid growth of peanut plants. During this period, a large number of flowering cones are needed, and the absorption of nitrogen, phosphorus and potassium by early-maturing varieties is the largest, accounting for more than half of the total absorption, while that of late-maturing varieties is close to half of the total absorption. The absorption of nitrogen and phosphorus reached the highest in the podding stage, accounting for more than half of the podding stage, and the root absorption capacity and nutrient absorption decreased in the mature stage.
