Fifth, the growth period: from the fleshy roots to the harvest are the fleshy root growth period. In this period, the fleshy roots are secondary to growth, and the intercellular space is also increasing, forming lateral growth. Therefore, the fleshy roots are gradually thickened from the slender shape of the seedling stage, and the spraying of the fruit is strong and the nutrient transport conduit of the underground fruit is thickened and improved. The fruit is swollen and energetic, the fruit surface is smooth, the fruit shape is strong, the quality is improved, and the high yield is achieved.
