Three ways to avoid the hollowness of radish

The hollow radish affects the yield, quality and economic benefit of radish. But there are also ways to prevent and control radish hollowness effectively. Pay attention to balanced water supply: the requirement of soil water content in the growth and development stage of radish is generally 60%-80%, especially in the expansion period of radish fleshy root, the soil water supply is insufficient or waterlogged during drought and drought, which is easy to cause hollow, so balanced water supply should be maintained. When the soil water content is lower than the above requirements, it should be watered properly. Scientific application of boron fertilizer: boron fertilizer can promote the heart of radish to grow bigger. From the beginning of Turnip Sprouts's growth of 2 or 3 true leaves to about half a month before harvest, boron fertilizer was sprayed every 20 days, with 150g borax or 100g boric acid per mu, dissolved in a small amount of warm water and then evenly sprayed on 60kg / 75kg of water. The appropriate time to spray is in the evening. Application of paclobutrazol: paclobutrazol has the function of controlling plant growth and reasonably regulating the distribution and transport of photosynthates in plants. In the radish plant growth period, 15 grams of paclobutrazol wettable powder per mu, 50 kilograms of water evenly sprayed, non-overgrowing fields can be used once.
