The root cause of fleshy roots is the rapid growth of cells, the lack of nutrients, and the rapid decrease in nutrient content in cells. Hollow mainly occurs when the growth of the leaf is nearly stopped, and the roots of the flesh expand rapidly, which is related to varieties, cultivation conditions and cultivation techniques. For example, early-maturing varieties are hollow, late-maturing varieties are hollow, sandy soils are hollow early, and hollow clay soil is late; poor soil drainage, high temperature and drought, uneven fertilization, and insufficient water supply are easy to hollow; too late harvesting or convulsions and flowering are also easy. Cause hollow. In order to avoid or reduce the occurrence of hollow phenomena, the above-mentioned various adverse factors should be avoided in cultivation.
