Hollow radishes affect the yield, quality and economic returns of the radish crop. But there are ways to effectively prevent hollow radishes.
Pay attention to balanced water supply: during the growth and development stages of radishes, the soil moisture content is generally required to be 60%-80%, especially during the root expansion stage of the radish. Insufficient soil water supply or alternating drought and waterlogging can easily cause hollowing, so a balanced water supply should be maintained. When the soil moisture content falls below the above requirement, water appropriately.
Scientifically apply boron fertilizer: boron fertilizer can help radishes develop solid cores and large size. Starting from when the radish seedlings grow 2-3 true leaves until about half a month before harvest, spray boron fertilizer once every 20 days. Each time, use 150 grams of borax or 100 grams of boric acid per mu, first dissolve in a small amount of warm water, then dilute with 60-75 kg of water and spray evenly. The best time to spray is in the evening.
Apply paclobutrazol: paclobutrazol has the function of controlling excessive plant growth and reasonably regulating the distribution and transportation of photosynthetic products within the plant. During the radish plant growth period, use 15 grams of 15% paclobutrazol wettable powder per mu, dilute with 50 kg of water and spray evenly. For fields where growth is not excessive, generally one application is sufficient.
