Radish planting: how to fertilize white radish?

How to fertilize white radish? Please introduce the method of fertilization radish absorption of nitrogen, phosphorus and potassium is slow at the initial stage of growth, and accelerates with growth. To the peak growth period of fleshy root, the absorption of nitrogen, phosphorus and potassium is the most. The absorption of nitrogen, phosphorus and potassium of radish varies greatly in different growth stages. Generally, the absorption of nitrogen is more in seedling stage, and the absorption of phosphorus and potassium is less. In the early stage of fleshy root expansion, the potassium uptake of plants increases significantly, followed by nitrogen and phosphorus. The peak period of nutrient absorption is in the fleshy root expansion stage. Therefore, ensuring adequate nutrition in this period is the key to high yield of radish. Fertilization method: under the medium fertility level, the amount of fertilizer applied to radish during the whole growth period was 3000kg / mu (or 350kg / mu of commercial organic fertilizer), 140kg of nitrogen fertilizer, 6kg of phosphate fertilizer and 911kg of potash fertilizer. Nitrogen and potassium fertilizer were divided into base fertilizer and secondary topdressing, all phosphate fertilizer was used as base fertilizer, and chemical fertilizer and farm manure (or commercial organic fertilizer) were mixed. Base fertilizer: 3000kg / mu farm manure or 350kg / mu commercial organic fertilizer, 5kg urea, 1317kg diammonium phosphate and 5kg potassium sulfate per mu. Topdressing: urea 11kg and potassium sulfate 8kg / mu in the early stage of fleshy root expansion, urea 9kg / mu and potassium sulfate 5kg / mu in the middle stage of fleshy root expansion. Extra-root topdressing: in the middle and later stages of growth, 0.3% calcium nitrate and 0.2% boric acid can be sprayed on the leaves for 2 times to prevent calcium deficiency and boron deficiency. At the same time, 0.2% potassium dihydrogen phosphate can be foliar sprayed to improve yield and quality. Click for more radish planting techniques click to get more vegetable planting techniques
