The latest course on planting techniques and methods of wasabi

Horseradish, the scientific name of horseradish, is a precious spicy vegetable of Cruciferae. Horseradish is a special food health product, and it is also the most common condiment in the world. Although the price is expensive, the market demand is not small. Horseradish has antibacterial and anti-cancer work, and has a small amount of planting in our country. So how to grow horseradish? Today, the editor brings you the planting technology of horseradish, let's have a look!

1. Select land for planting

First of all, we need to select planting plots before planting. Horseradish is suitable for growing on plots with high topography, rich vegetation, strong permeability and fertile soil. After choosing a good site, make a little soil preparation, control the planting density and dig a good planting hole, because horseradish prefers to live in a shady environment. Therefore, it is necessary to properly cover the sunshade net on the planting ground. Before sowing after the preparation work is done, the seeds should first be harvested and frozen in an environment of about 2 degrees for 3 months, and then sown in mid-October. Under normal circumstances, Ching Ming Festival can emerge before and after the second year, do a good job in seedling management, and transplant in time when growing to a certain height.

2. topdressing at the right time

First of all, when we prepare the soil, we should apply sufficient base fertilizer, which is mainly based on fully mature farm manure, and control the amount of base fertilizer according to the soil area. Then, after the seedlings were successfully planted, the seedlings should be fertilized properly according to the overall situation of the seedlings and the amount of base fertilizer applied. The fertilizers of topdressing are mainly compound fertilizers such as nitrogen, phosphorus and potassium, and the times of topdressing in the growth period should not be less than twice. Usually in the spring and autumn must be applied once, fertilizer should pay attention to the position, do not let fertilizer contact with the roots of horseradish, to prevent burning roots, causing diseases and insect pests and other problems that threaten the growth of wasabi.

3. Ploughing and weeding

During the growth period of horseradish, weeds pose a great threat to its growth. Therefore, we must do a good job in weeding. If weeds are not weeded in time and weeds exceed the height of horseradish, weeds will block the sun of horseradish, seize the growth nutrients of horseradish, inhibit the growth of horseradish, and increase the incidence of various diseases and insect pests. Therefore, we should regularly plough weeds, intertillage can not only play a good weeding effect, but also improve the permeability of the soil and enhance the nutrient absorption of the roots. And weeding to prevent damage to the roots, such as horseradish plant wounds, timely disinfection to prevent infection.

4. Pest control

Because horseradish likes to grow in a cool and humid environment, the incidence of diseases and insect pests is very high. If we do not do a good job in the prevention and control of diseases and insect pests, it may lead to the death of horseradish all over the land, and the planting efficiency will be seriously affected. First of all, avoid repeated cultivation of wasabi, and then disinfect the field regularly to reduce any substances that may cause diseases and insect pests. Then as much as possible to promote horseradish rhizome expansion, early harvest time, can effectively control diseases and insect pests. In addition to strengthening field management, we also need to make preparations for various pest control measures, such as understanding what kind of chemicals are used for different diseases and insect pests, and minimizing losses after the disease, so as to ensure our own planting benefits.

The above is a brief introduction of horseradish planting technology. Horseradish is very popular in China and even all over the world. The cultivation of horseradish is actually relatively simple, but the incidence of diseases and insect pests is much higher than that of other crops, so we must do a good job in pest control when planting. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
