Fertility requirements Large radish is a cruciferous herb. Large radish has a wide adaptability to the soil. In order to obtain high-yield and high-quality products, it is still better to use deep, porous, well-drained, and relatively fertile sandy loam. The growth period of radish is divided into the germination period, the seedling period, the leaf growth period, and the fleshy root growth period.
Large radish has a large absorption of nitrogen, phosphorus, and potassium. It is a high-yield crop with a high requirement for fertilizer. For each 1,000 kilograms of big radish, about 2.1 to 3.1 kilograms of nitrogen (N) is absorbed from the soil. P2O5) 0.8 ~ 1.9 kg, potassium (K2O) 3.5 ~ 5.6 kg, the ratio is roughly 1:0.5:1.8. The absorption of nutrients is different at different growth stages of radish, and the nutrient uptake gradually increases with growth and development. In the early stage of growth, nitrogen, phosphorus, and potassium are absorbed slowly. With the increase of growth and absorption, the absorption of nitrogen, phosphorus, and potassium is the most abundant during the period of peak growth of straight roots. The absorption of nitrogen, phosphorus, and potassium in big radish varies greatly during different growth stages, and the amount of nitrogen uptake during the seedling period is generally large, and the absorption of phosphorus and potassium is small. In the early stage of root swelling, the absorption of potassium by the plant is significant. The increase was followed by nitrogen and phosphorus, and it was at the peak of nutrient absorption during the peak period of root enlargement. Therefore, ensuring adequate nutrition during this period is the key to high yield of large radish. Radish is sensitive to nitrogen, nitrogen deficiency will reduce the yield of radish, and the more nitrogen deficiency in the early growth period, the greater the impact on the yield, excess nitrogen, phosphorus and potassium are insufficient, it will cause some of the above ground greed. Radish and other cruciferous vegetables, like soil drought and other reasons, easily lead to calcium deficiency or lack of boron symptoms, lack of calcium from the point of growth near the tip of the blade withered, the lack of boron when the root of the root becomes brown, that is, brown rotten Heart disease.
Fertilization technology Large radish fertilization rate per mu for the whole growing period is 3,000~3,500 kilograms of farmyard fertilizer (or 350~400 kilograms of commodity organic fertilizer), 14 to 16 kilograms of nitrogen fertilizer (N), 6 to 8 kilograms of phosphorus fertilizer (P2O5), and potassium fertilizer (K2O). 9 to 11 kg, organic fertilizer as base fertilizer, nitrogen and potassium fertilizer sub-basal fertilizer and top dressing, phosphate fertilizer as base fertilizer, fertilizer and farmyard fertilizer (or commercial organic fertilizer) mixed application.
base fertilizer. The basal fertilizer is applied to 3,000 to 3,500 kilograms of farmyard manure (or 350 to 400 kilograms of commodity organic fertilizer), 5 to 6 kilograms of urea, 13 to 17 kilograms of diammonium phosphate, and 5 to 7 kilograms of potassium sulfate.
top dressing. The root enlargement period of meat is the peak period of nutrient absorption. During this period, it is reasonable to top-dress fertilizer to meet the nutrient requirements of radish, which is an important guarantee for high yield and high quality. The early stage of fleshy root enlargement: 11 to 13 kg of urea per gram, and 8 to 9 kg of potassium sulfate. Fermentation of fleshy roots at the height of growth: 9 to 10 kg of urea and 5 to 6 kg of potassium sulfate per acre.
Root dressing outside. In the late growth stage, 0.3% calcium nitrate and 0.2% boric acid can be used to spray 2 or 3 times to prevent calcium deficiency and boron deficiency. At the same time, 0.2% potassium dihydrogen phosphate can be sprayed on the leaves to increase the yield and quality. Facilities cultivation can add carbon dioxide gas fertilizer.
