Three cultivation measures to keep radishes from becoming hollow
Three measures to keep radishes from becoming hollow
1. Pay attention to balanced water supply. During the growth and development stages of radishes, the soil moisture content should reach 60%-80%. Especially during the stage when the fleshy root of the radish expands, insufficient soil water supply or alternating drought and waterlogging can easily lead to hollowing. Therefore, water supply should be balanced during cultivation, and when the soil moisture content is lower than required, appropriate watering should be done.
2. Apply boron fertilizer scientifically. Boron fertilizer can help radishes have solid hearts and large size. From the time the radish seedlings grow 2-3 true leaves until 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 it in a small amount of warm water, then add 60-75 kg of water, stir evenly, and spray in the evening.
3. Apply paclobutrazol. Paclobutrazol has the effect of controlling excessive plant growth and regulating the distribution and transport of photosynthetic products within the plant. During the radish growing period, use 15 grams of 15% paclobutrazol wettable powder per mu, add 50 kg of water, and spray evenly. For fields with normal growth, generally one application is enough.
