Select a small variety of dense radish succulent, fleshy root growth is slower, balance of leaves and roots, not easy to worry about heart; large fleshy radish, fleshy root growth is too fast, root growth is greater than leaf growth, easy to worry about. Therefore, small radish varieties with fine meat quality should be selected. Timely planting appropriate sowing, do not grab early. Early sowing, radish growth during the night high temperature, growth stagnation, consume large amounts of nutrients, easy to worry; appropriate sowing, radish in the high daily temperature, low night temperature, large temperature difference between day and night, normal growth, not easy Hearty. Scientific close-growing radish grows too fast under conditions of fertile soil and wide plant spacing. The growth of leaves and roots is unbalanced and prone to cramps. Therefore, generally large-sized varieties spacing 50 to 60 cm, spacing 20 to 30 cm; medium-sized spacing 40 to 50 cm, spacing 15 to 20 cm; small varieties of plants, spacing 8 to 10 cm. Rational fertilization of fertilizer should be based on the principle of basal fertilizer, supplemented by top dressing, focusing on the reasonable combination of nitrogen, phosphorus and potassium. Long-term growth of large varieties, topdressing can be less chasing chase, top dressing in the seedling stage, leaf growth period and root expansion, can be used in combination with urea, superphosphate, potassium sulfate. Appropriate watering to control soil moisture to prevent over-drying and over-wetting. Use the method of “drought-irrigation, cloudy pouring†to keep the soil moisture at 70%-80%. In the middle and late stages of growth, the amount of water required is large, and sufficient water supply should be provided. However, the amount of watering should not be excessive in order to prevent excessive growth on the ground. Scientific storage of winter radish, cellar temperature is too high, the humidity is low, due to rapid respiratory depletion and water loss occurred. The temperature of the cellar is too low, and the fleshy roots are susceptible to chilling. Radish suitable storage temperature is 0 ~ 2 °C, air humidity is 95%.

Radishes often appear cramped during growth and storage. After the heart is weighed, not only the weight is reduced, but also the starch and sugar are reduced. In addition, the tissues are soft, the flavor is lightened, the food value is reduced, and it cannot be stored. According to Guo Zhiqing, associate professor of the College of Horticulture, Northwest A&F University, prevention and control of carrots mainly focus on the following points:
