How to Grow Horseradish? The Latest Cultivation Techniques and Methods Tutorial
Horseradish is a kind of condiment sauce, but what everyone would never guess is that horseradish actually originated as a vegetable. Horseradish is native to Europe and was later gradually introduced to our country for cultivation; it is the base material for horseradish sauce. It is very popular in our country, so the cultivation area of horseradish has also grown larger. So how should horseradish be cultivated? Below, the editor brings you the cultivation techniques for horseradish, so let's take a look!
1. Seed and Site Selection
First, we should select good horseradish seed without obvious wounds and free of pests and diseases, then choose soil with high terrain, dryness and high fertility as the planting site. Before planting, the land preparation work should be done first: first plow the land deep about 35 cm, form ridges and disinfect. Then apply sufficient base fertilizer; the base fertilizer is mainly farmyard manure, combined with a small amount of compound fertilizer. Then plant it on top of the ridge. The planting period for horseradish is relatively long, generally carried out around the Beginning of Spring each year. When sowing, control the sowing density well and ensure sufficient soil moisture; after sowing, cover with about 4 cm of soil and cover with plastic film.
2. Timely Planting
The planting time for horseradish should be chosen in spring and autumn, because the temperatures in summer and winter are too extreme and not conducive to the growth of horseradish. Usually the best planting time is around the Qingming Festival each year. Dig the planting holes on top of the ridge, controlling the density and depth well. The planting holes should maintain an inclination of about 45 degrees to the ground; after planting, cover with fine soil and smooth and refine the top of the ridge. Spray an appropriate amount of herbicide and cover with plastic film; the film must be firm, pressed and compacted to prevent it from being blown away by the wind. If planting by sowing, small holes should be made in the film, then the small holes should be buried in the soil, which is conducive to seed germination and seedling emergence.
3. Thinning and Replanting
If horseradish is sown and planted in spring, under normal management it will break through the soil in about a month. During the seedling stage, because the pungent taste of the roots has not yet fully developed, the damage from pests and diseases is relatively great. After emergence, we should regularly observe the growth of the seedlings. If weak seedlings damaged by pests and diseases or dead seedlings are found, they should be pulled out in time, and then healthy horseradish seedlings should be replanted. And when the seedlings grow to a certain height, the thinning work should be done well, after which the ridge can be closed and the seedlings fixed.
4. Fertilization Management
The growth of horseradish has a relatively high demand for fertilizer. When the seedlings grow to about 12 cm, the first topdressing work needs to begin. At this stage, the fertilizer is mainly urea, with the purpose of promoting seedling growth and increasing the growth rate. Then comes early summer; early summer is when horseradish has the strongest growth capacity and a very great demand for nutrients. At this time, nitrogen-phosphorus-potassium compound fertilizers such as urea and potassium sulfate should be applied as topdressing to promote plant leaf growth, strengthen photosynthesis and increase nutrient accumulation.
The above is a brief introduction to horseradish cultivation. Of course, horseradish also has a certain demand for water, especially for those seedlings and replanted seedlings with relatively weak growth capacity, which should be watered heavily to improve the survival rate. After the middle stage, there are very few pests and diseases on horseradish, because the pungent taste of horseradish is very strong and many pests do not like it. That is all for today's introduction. This article is for reference only. Thank you for your reading and support.
