(2) Watering is adequately watered during the germination period, and the soil water content is above 90%. In the seedling stage, the seedlings are shallow, the water requirement is small, and the soil water content is 60%. Master the principle of less pouring and pouring. The leaf area needs more water during the growing season and is moderately irrigated. The root growth period should be adequately and evenly supplied to maintain soil moisture between 70% and 80%. The roots should be properly watered in the later stages of growth to prevent hollowness.

(3) The principle of fertilization by staged topdressing radish is based on base fertilizer and supplemented by top dressing. Generally, after topdressing, the fertilizer is applied 2 to 3 times, and the concentration should not be too large.
