The latest course on cultivation techniques of horseradish

Horseradish is a kind of sauce, but it is unexpected that the predecessor of horseradish is actually a kind of vegetable. Horseradish originated in Europe and was gradually introduced into China. It is the basic material of horseradish sauce. It is very popular in our country, so the planting area of horseradish has become larger. So how to grow horseradish? The following editor has brought you the cultivation techniques of horseradish, let's take a look!

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 then choose high-lying, dry and fertile soil as the planting site. Before planting, we should first do a good job of soil preparation, first turn the ground depth of about 35 centimeters, ridging and disinfection. Then apply sufficient base fertilizer, the base fertilizer is mainly farm manure, combined with a small amount of compound fertilizer. Then plant it on the top of the ridge, the planting period of horseradish is relatively long, generally planted before and after the Beginning of Spring every year. When sowing, it is necessary to control the sowing density and ensure sufficient 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 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 the density and depth, and so on. The planting hole should maintain an inclination of about 45 degrees with the ground, cover the fine soil after planting, and make the top of the ridge smooth and fine. Spray the right amount of herbicide, cover the plastic film, the plastic film must be firm, and compact it to prevent it from being blown away by the wind. If it is sowing and planting, the plastic film should make a good hole, and then bury the hole 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, the soil will be broken in about a month under normal management. In the seedling stage, because the spicy taste of the roots 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 or dead seedlings harmed by diseases and insect pests, we should pull them out in time, and then make up the strong horseradish seedlings. And when the seedlings grow to a certain height, it is necessary to do a good job of inter-seedling work, and then can seal the seedlings.

4. Fertilization management

The growth of horseradish needs more fertilizer, and when the seedlings grow to about 12 centimeters, they need to start the first topdressing work. The fertilizer at this stage is mainly urea, the purpose is to promote the growth of seedlings and improve the growth rate. Then is the early summer, early summer is the strongest growth capacity of horseradish, 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 a brief introduction to horseradish cultivation, of course, horseradish also has a certain demand for water, especially for those seedlings and seedlings with relatively weak growth ability to be watered to improve the survival rate. After the middle period, there are very few diseases and insect pests of horseradish, because the spicy taste of horseradish is so strong that many insect pests do not like it. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
