Cultivation techniques of horseradish (horseradish radish)

Horseradish, which originated in Europe, is not only a raw material for seasoning, but also a vegetable, which has been gradually cultivated in China in recent years. Today, the editor will introduce the cultivation techniques of horseradish.

1. Selection of species and sites

First of all, we should choose good horseradish species with no obvious wounds and no diseases and insect pests, and choose high-lying, dry and fertile soil as the planting ground. Before planting, we should first do a good job of soil preparation, first turn the ground over about 35 cm, ridge and disinfect, then apply sufficient base fertilizer, which is mainly farm manure, combined with a small amount of compound fertilizer, and then plant it on the top of the ridge. the planting period of horseradish is relatively long. Generally, before and after the Beginning of Spring is planted every year, when sowing, it is necessary to control the sowing density and ensure adequate moisture, cover about 4 cm of soil after sowing, and cover the plastic film well.

2. planting at the right time

The planting time of horseradish should be chosen in spring and autumn, because the temperature in summer and winter is too extreme, which is not conducive to the growth of horseradish. Usually the best planting time is around Ching Ming Festival every year, dig planting holes at the top of the ridge, control density and depth, etc., planting holes should maintain an inclination of about 45 degrees with the ground, cover fine soil after planting, smooth and fine the top of the ridge, spray appropriate amount of herbicides, cover the plastic film, and the plastic film must be firm. It should be compacted to prevent it from being blown away by the wind. If it is sowing and planting, small holes should be made in the plastic film, and then the holes should be buried in the soil, which is conducive to seed germination and emergence.

3. Replenish seedlings with inter-seedlings

If it is horseradish sown and planted in spring, under normal management, the soil will be broken in about a month. At the seedling stage, because the spicy taste of the root has not yet come out completely, the harm caused by diseases and insect pests is relatively great. After emergence, we should regularly observe the growth of the seedlings. If we find that there are weak seedlings or dead seedlings endangered by diseases and insect pests, we should pull them out in time, and then make up the strong horseradish seedlings. When the seedlings grow to a certain height, it is necessary to do a good job of interseedling work, and then the seedlings can be sealed.

4. Fertilization management

The demand for fertilizer for the growth of horseradish is relatively large. When the seedlings grow to about 12 cm, it is necessary to start the first topdressing work. The fertilizer at this stage is mainly urea, the purpose is to promote the growth of seedlings, improve the growth rate, and then it is early summer. Early summer is when horseradish has the strongest growth ability, and the demand for nutrition is very great. At this time, nitrogen, phosphorus and potassium compound fertilizers such as urea and potassium sulfate should be applied to promote plant leaf growth, strengthen photosynthesis and improve nutrition accumulation.

The above is the horseradish cultivation techniques introduced to you by the editor. I hope I can help you!
