How to grow kohlrabi? A detailed guide to the cultivation method

Kohlrabi is a common vegetable in our daily life, but it usually appears on our tables in pickled form. The preparation of kohlrabi is actually the same as pickled dried radish strips - it can be eaten directly, and of course it can also be stir-fried. Kohlrabi is widely distributed in China, and it is basically grown all over the country. Let us learn about the cultivation method of kohlrabi together below.

1. Site selection and land preparation

Kohlrabi has the characteristics of preferring cool and moist conditions, but it is relatively poor in cold resistance and drought resistance, which means that soil temperatures that are too high or too low, or soil that is too dry or too wet, are all unsuitable for kohlrabi growth. When choosing a planting site, generally fields used for growing Chinese cabbage can also be used for kohlrabi, but what we need to pay attention to is the improvement of the land. We should ensure that the field has appropriate moisture, and at the same time reasonably control the temperature of the planting site. The soil layer of the planting site should be deep and the soil texture loose, which is beneficial to the growth of the kohlrabi tuber.

2. Sowing and raising seedlings

Before planting kohlrabi, the seedlings need to be raised first. First, we need to select seeds, then sun-dry the selected plump seeds, and finally soak the seeds in water. After the seeds have fully absorbed water, take them out and place them in an environment with a temperature of about 25 degrees to sprout. When most of the seeds have cracked open and grown white spots, we can sow them. Sowing can be done in two ways: direct sowing or drilling. Note that the seeds should be buried in the soil, so as not to affect the germination rate of the seeds.

3. Transplanting and setting out seedlings

The time from sowing to emergence for kohlrabi is generally 3 to 15 days, depending on the different sowing seasons. When the kohlrabi seedlings have grown to about 10 to 15 cm, we can pull up the seedlings and transplant them. When pulling up the seedlings, control the force; it is best to water before pulling up the seedlings to make the soil loose and moist, so that the seedlings are not easily damaged, thereby improving the survival rate of the seedlings. When planting, set them out at a density of 50 cm between rows and 40 cm between plants, to ensure the yield and quality of kohlrabi.

4. Cultivation management

After kohlrabi is set out, we should water once, so that it can adapt to the new environment more quickly and grow new roots. Within 10 days after setting out, check the survival of the seedlings in the field, replant missing seedlings in time, and carry out the first topdressing and intertillage weeding, to promote the growth of kohlrabi seedlings and improve the utilization rate of nutrients. Because kohlrabi has a relatively large demand for water, it generally needs to be watered about once every 3 days. In order to promote the enlargement of the underground tuber, we also need to apply appropriate topdressing, mainly phosphorus and potassium fertilizer, and of course farmyard rotted manure can also be used directly, with very good results as well.

5. Pest and disease control

Kohlrabi is a vegetable with relatively strong resistance, and throughout its entire growth process, pests and diseases actually rarely occur. However, due to the reason of the planting season, viral diseases may appear. For viral diseases, we need to strengthen the control of field moisture and combine it with chemical agents for prevention and control; consult a specialist for the specific agents. Secondly, pay attention to the impact of aphids on kohlrabi. They mainly harm the branches and leaves of kohlrabi, and pyrethroid insecticides can be used for control.

From the above introduction to the cultivation method of kohlrabi, I believe everyone has basically understood it clearly. Of course, there is still a lot that the editor has not covered. Due to limited time and energy, the editor has not explained them one by one in detail. If you have any questions, you can leave a message below.
