What are the precautions for growing wasabi? These key points you need to master
Wasabi is currently an extremely precious condiment food internationally. It not only tastes good, but is also rich in nutrients, and has multiple pharmacological effects such as antibacterial, anti-cancer, and antioxidant properties. It is extremely popular on the market, with huge market demand and a high price. Many people, aiming at its commercial value, are preparing to start growing it, but because this plant is relatively rarely cultivated, they do not know much about it. Below, the editor will bring you its cultivation precautions.
1. Land selection
To grow wasabi, you must first choose soil suitable for its growth. Wasabi relatively prefers plots with higher terrain, surrounding vegetation, and loose, fertile soil. After choosing the planting site, you must carry out land preparation and dig planting holes. Because wasabi prefers a shady and humid environment, after land preparation you must install shade nets well to create an environment suitable for its growth. After that, you can sow. But before sowing, its seeds must be treated: place the seeds in an environment of about 2 degrees for 3 months to break dormancy, then choose to sow in October.
2. Applying base fertilizer
Wasabi is a perennial plant, and its growth is relatively slow. Therefore, in order to speed up its growth, we must apply base fertilizer during land preparation. The base fertilizer should preferably be fully decomposed farmyard manure, and the application amount is determined by the size of the plot. In addition, after the seedlings are planted, they should also be topdressed in time according to the growth condition of the seedlings to promote seedling growth. The topdressing can mainly be NPK compound fertilizer. Generally, topdressing is needed 2 times during the growth period. When topdressing, be careful not to let the fertilizer directly touch its roots, so as to avoid burning the root system.
3. Intertillage and weeding
During the growth and development of wasabi, weeds in the field still have a relatively large impact on it. Therefore, during cultivation, inspections should be carried out from time to time. Once it is found that there are relatively many weeds, intertillage and weeding should be carried out in time. If the weeds are too tall, they will affect the light conditions of wasabi, cause its growth to be poor, and also easily breed pests and diseases. Intertillage and weeding can not only loosen the soil and enhance the absorption capacity of the root system, but also increase the permeability between plants and reduce pests and diseases. However, when carrying out intertillage and weeding, be careful not to go too deep, so as to avoid damaging the wasabi root system.
4. Pest and disease control
Wasabi likes to grow in dark, sheltered environments, and such an environment inevitably leads to pests and diseases. If pest and disease control work is not done well, it will at best lead to reduced yield, and at worst lead to total crop failure, causing great harm. The field should be disinfected regularly to minimize the occurrence of pests and diseases. When pests and diseases are found, do not panic; confirm the condition and apply the right treatment.
