How to prevent hollowness of radish

Radish is a vegetable with fleshy root as its product. hollow and cracking often occur in the production of fleshy root, which directly affects the yield, quality and economic benefit of radish. In order to prevent radish hollowness and increase farmers' income, several methods to prevent radish hollowness are introduced for reference. 1. Balanced water supply radish in the growth and development stage, the soil moisture is required to be 65% Mel 80%, especially during the expansion period of radish fleshy root, which is the period when radish needs the most water in its life. It is necessary to keep the soil moist frequently. Soil water supply is insufficient or suddenly dry and wet, which can easily lead to radish hollow. Therefore, a balanced water supply should be maintained during the fleshy root expansion period, and when the soil moisture is less than 65%, it should be properly watered. But the amount of water should not be too large, in case of rainstorm, it should be drained in time to prevent root cracking or rotting. 2. Boron supplementation and potassium boron fertilizer can promote the heart size of radish, and potassium can promote the high quality and high yield of radish. Boron should be replenished when 4 true leaves are grown from radish, usually 20 days before radish harvest. 0.3% potassium dihydrogen phosphate solution was sprayed every 10 murals every 15 days when the fleshy root began to expand. It can effectively prevent the hollow radish, improve the quality and increase the output. 3. Coordinated growth and balanced growth of aboveground and underground parts is the key to prevent hollow radish and obtain high quality and high yield of radish. In the management, we should implement balanced fertilization, strengthen ploughing and loosening the soil, prevent the excessive growth of leaves, and promote the plant to turn into the growth of fleshy roots in time.
