Planting and management of white radish

White radish planting should choose rich humus, deep soil layer, good drainage, loose and ventilated sandy soil, pH 5.3-7.0 is the best. It requires plenty of light and likes a mild and cool environment. The germination temperature is 20 to 25 degrees and the temperature for leaf growth is 15 to 20 degrees. The soil humidity is best at 65-80%, and the air humidity is 80%-90%. To prevent and control diseases and insect pests such as mosaic, virus, soft rot, black heart, aphids and cabbage caterpillar.

1. Soil: planting white radish had better choose rich humus, deep soil layer, good drainage, loose and ventilated sandy soil, pH 5.3-7.0 is appropriate, the best choice melon or bean stubble, no pesticide residue plot.

2. Light: white radish requires sufficient light, photosynthesis is strong, the more material accumulation of white radish, the faster the fleshy root expansion speed, and the higher the yield. If light is insufficient, carbohydrate accumulation is low, fleshy root expands slowly, yield is low, quality is poor.

3. Temperature: White radish belongs to semi-cold-resistant vegetables, like mild and cool, temperature difference larger climate. Seeds germinate at 2 to 3 degrees Celsius, and the optimum temperature for germination is 20 to 25 degrees Celsius. The seedling stage can withstand high temperatures of about 25 degrees Celsius and low temperatures of minus 2 to 3 degrees Celsius for a short period of time. The suitable temperature for leaf growth is 15 to 20 degrees Celsius, and the optimum temperature for fleshy root expansion is 13 to 18 degrees Celsius.

4. Moisture: White radish is not drought-resistant, soil moisture is 65 to 80 percent of the maximum water holding capacity, and air humidity is 80 to 90 percent. Too much water and insufficient air in the soil affect the absorption and expansion of fleshy roots, and the epidermis is rough. Uneven water supply can also cause fleshy roots to crack.

5. Diseases and pests: white radish main diseases are mosaic disease, virus disease, soft rot and black heart disease, etc., the main pests are aphids, cabbage insects, etc. The key of disease control lies in strengthening cultivation management, making plants robust, enhancing disease resistance ability, and integrated control combined with chemical control.

6. Harvesting: When the leaf color turns yellow and fades, the fleshy root is fully expanded and the base is round and blunt, that is, it reaches the commodity standard, and it can be harvested at this time.

White radish, also known as small ginseng, is a very popular food in the market. White radish cultivation and management are also relatively simple. It can be planted in both the south and the north.
