Radish is a vegetable with fleshy root as its product. In the production of fleshy roots, hollowing, cracking and other phenomena often occur. After the radish is hollow, the yield, quality and economic benefits of radish are directly affected. In order to prevent the hollowness of radish and increase the income of peasants, several methods for preventing the radish hollow are introduced for reference.

Balanced water supply Radish growth and development stage, the required soil moisture is 65% -80%, especially in the radish root mass expansion period, is the radish water demand for the most life, must always keep the soil moist, insufficient soil moisture supply or dry Humidity, it is easy to cause radish hollow. Therefore, it is necessary to maintain a balanced water supply during the root swelling period, and when the soil moisture is lower than 65%, appropriate watering should be performed. However, the amount of watering should not be too large. In case of heavy rain, it should be drained in time to prevent rooting or rot.

The addition of boron and potassium fertilizer can promote the growth of radish, potassium can promote high quality and high yield of radish. When radish grows 3-4 true leaves, it is necessary to make up the boron, generally 20 days before the radish harvest. A 0.3% potassium dihydrogen phosphate solution was sprayed every 10-15 days when the fleshy root began to swell. Can effectively prevent radish hollow, improve quality, increase production.

Coordinating the growth and development of the balanced growth between the upper part and the lower part of the underground is the key to preventing the radish from being hollow and obtaining high quality and high yield of radish. In the management, we must implement balanced fertilization, strengthen the cultivating loose soil, prevent the leaves to grow long, and prompt the plant to turn into the growth of the fleshy root.
