Three measures for non-hollow radish

First, pay attention to a balanced water supply. The soil water content in the growth and development stage of radish should reach 60% to 80%, especially in the expansion period of radish fleshy root, when the soil water supply is insufficient or when the soil is dry and waterlogged, it is easy to appear hollow phenomenon, so the water supply should be balanced during cultivation. When the soil water content is lower than the requirement, it is necessary to water properly.

Second, apply boron fertilizer scientifically. Boron fertilizer can promote the heart and size of radish. From the period from the growth of 2 to 3 true leaves of Turnip Sprouts to the harvest period, 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 60g 75kg of water, stirred evenly and sprayed in the evening.

Third, apply paclobutrazol. Paclobutrazol can control the overgrowth of plants and regulate the distribution and transport of photosynthates in plants. During the growing period of radish, 15 g 15% paclobutrazol wettable powder per mu was sprayed evenly after 50 kg of water. The normal growth of the field can be used once.
