Why did the fleshy root of radish break?

Why did the fleshy root of radish break? Please introduce the reason for the rupture of radish fleshy root. Physiologically, it is considered to be the result of uneven soil water supply during radish growth. That is, the radish encounters high temperature and drought during the growing period, and the soil moisture is insufficient, resulting in the gradual hardening of the cortex tissue of the radish fleshy root. In the middle and later stage of the growth of radish, the temperature is suitable, the sun is suitable, and the water is sufficient. Under such a good environment, the parenchyma cells of xylem in radish fleshy roots divide and expand rapidly, increasing the power of expansion horizontally towards the cortex, while the hardened cortex can not grow accordingly and there is a contradiction. The hardened cortex can not expand from the inside to the outside of the skin. As a result, the cortex is cracked. On the other hand, the soil that is too sticky or too hard, or the environment in which the sand is too thick, the groundwater table is too high, and the larvae of underground pests such as yellow striped beetles have eaten the outer skin of the root, these environments will leave some small marks on the root epidermis. In addition, harmful substances leave ugly black lines. How to prevent the phenomenon of rupture and rough skin? The most basic thing is to choose a good soil, fully turn the sun, intensive cultivation, often keep the soil loose, and create a good soil environment. In management, according to the weather and radish growth performance, timely and uniform water supply, so that the soil remains moist and breathable, radish growth and fleshy root formation process is not lack of water, no lack of nutrition, no lack of air, no soil squeeze, do not dry when wet or long-term not drenched.
