Detailed Explanation of Wasabi Planting Techniques and Management Methods

Wasabi, whose scientific name is Eutrema japonicum (wasabi), is a precious pungent aromatic vegetable of the Brassicaceae family. Wasabi is a special edible health product and also one of the most common condiments in the world. Although its price is relatively high, market demand is not small. Wasabi has antibacterial and anticancer properties, and it is grown on a small scale in China. So how should wasabi be planted? Today, the editor brings you the planting techniques for wasabi. Let's take a look below!

1. Land Selection and Planting

First, before planting, we need to select a good planting plot. Wasabi is suitable for growing on plots with higher terrain, abundant vegetation, strong permeability and fertile soil. After selecting the land, slightly prepare the soil, control the planting density and dig the planting holes well, because wasabi prefers to live in shaded environments. Therefore, shade nets need to be appropriately covered over the planting plot. After the preparatory work is done, sow the seeds. First, after harvesting, the seeds should be placed in an environment of about 2 degrees for 3 months of freezing, and then sown in mid-October. Under normal circumstances, seedlings emerge around Qingming Festival the following year. Do a good job in seedling management, and when they grow to a certain height, transplant and establish them in the field at the appropriate time.

2. Timely Topdressing

First, when preparing the soil, we should apply sufficient base fertilizer. The base fertilizer is mainly fully decomposed farmyard manure, and the amount of base fertilizer should be controlled according to the soil area. Then, after the seedlings are successfully established, appropriate topdressing should be carried out according to the overall condition of the seedlings and the amount of base fertilizer applied. The topdressing fertilizer is mainly compound fertilizer such as nitrogen, phosphorus and potassium. The number of topdressings during the growth period must not be less than two. Usually, topdressing must be applied once in both spring and autumn. When topdressing, pay attention to the position and do not let the fertilizer touch the wasabi roots, to prevent burning the roots and causing problems such as pests and diseases that threaten wasabi growth.

3. Cultivation and Weeding

During the wasabi growth period, weeds pose a great threat to its growth. Therefore, we must do a good job in weeding. If weeding is not done in time and the weeds exceed the height of the wasabi, the weeds will block the wasabi's sunlight, compete for nutrients needed for wasabi growth, inhibit wasabi growth, and increase the incidence of various pests and diseases. Therefore, we should regularly cultivate and weed. Cultivation can not only achieve a good weeding effect, but also improve soil permeability and enhance nutrient absorption by the roots. Also, when weeding, prevent damage to the roots. If wounds appear on wasabi plants, disinfect them in time to prevent infection.

4. Pest and Disease Control

Because wasabi likes to grow in cool and humid environments, the incidence of pests and diseases is very high. If pest and disease control work is not done well, it may cause all wasabi in the field to die, and planting benefits will be seriously affected. First, avoid continuous cropping of wasabi, then regularly disinfect the field to reduce any substances that may cause pests and diseases. Then, as much as possible, promote the expansion of wasabi rhizomes and advance the harvest time, which can effectively prevent and control pests and diseases. In addition to strengthening field management, we also need to prepare various pest and disease control measures, such as understanding what chemicals to use for different pests and diseases, and minimizing losses after outbreaks, so as to ensure our own planting benefits.

The above is a brief introduction to wasabi planting techniques. Wasabi is very popular in China and even around the world. Wasabi cultivation is actually relatively simple, but its incidence of pests and diseases is much higher than that of other crops, so everyone must do a good job in pest and disease control when planting.
