Cultivation and management of chicory;
Planting: The planting season of chicory is mainly spring and autumn. Spring sowing should be done sooner rather than later, which can prolong its vegetative growth period and harvest period. Seedlings can be raised in hotbeds, and planted with 7-9 leaves, with a spacing of 20cm and a row spacing of 30cm.
It is feasible to sow directly in the open field, but it needs thinning seedlings to facilitate plant growth. Autumn sowing can be divided into early autumn sowing and late autumn sowing.

Water 2-3 times in the early growth stage, usually more in spring and less in autumn. According to the soil hardening, combined with watering, intertillage and loosening. At the peak of growth, available nitrogen fertilizer should be applied with water to promote the growth of leaves, increase their thickness and improve their yield and quality.
