Kohlrabi can be directly seeded or transplanted, but in order to facilitate the management and make full use of the land, seedling transplanting is mostly used. It likes the cold environment and the suitable temperature for growth is 15-20 degrees. The higher temperature in the early stage is beneficial to the growth of its seedlings, while in the later stage, the temperature is low and the temperature difference between day and night is large, which is beneficial to the expansion of fleshy roots. Its sowing time is determined according to the local climatic conditions, and the seedling raising method is the same as that of Chinese cabbage. After 10 days of emergence, the seedlings should be treated with fertilizer and water management. when there are 4-5 true leaves, they can be planted.

Loam with deep, fertile soil and convenient drainage and irrigation should be chosen as the planting site, and the previous crop should be a vegetable field or rice field that has never been a cruciferous family.

After survival, the water should be properly watered according to the weather conditions, and the water should be properly controlled before the fleshy root expands, so as to make the straight root grow deep, keep the soil moist after expansion, and pay attention to control moisture when the fleshy root is formed in the later stage. Generally stop watering in one week of harvest to enrich the tissue and improve the quality. Topdressing once after planting for 10 days, and then once a week. When the fleshy root is enlarged, it is necessary to re-apply 1-2 fertilizer, especially potash fertilizer, loosen the soil and weed before each fertilization, and sprinkle water after 1-2 days of fertilization to promote fertilizer dissolution and absorption of crops. Cultivate the soil 1-2 times during the growing period, so as not to affect the quality of the root system.
