What fertilizer is needed for radish? How to apply fertilizer is reasonable? Agricultural experts said that the demand for nitrogen and potassium from radish is large, and the demand for phosphorus is small. The absorption ratio of three elements is potassium> nitrogen> phosphorus. In the early growth stage, the amount of nitrogen absorbed by radish increases, and the rate of nitrogen absorption in the middle and late stages slows down. The absorption of potassium is low in the early stage and more in the later stages. The potassium content in the root is high; the absorption of phosphorus is low and slow. Radish root bared shoulders before the main period is the growth period of the leaves, after the bare shoulder is the peak of the root swelling of the flesh, radish fertilization should be sufficient decomposed organic fertilizer or fast-acting nitrogen fertilizer as a base fertilizer, combined with soil preparation into the soil. Fertilizer can be properly grasped depending on the variety and seedling stage, usually after 2-3 times dressing in bare shoulder, radish is also prone to calcium deficiency and boron deficiency symptoms, should pay attention to prevention and treatment.
