How to plant Jerusalem artichoke

Jerusalem artichoke is a perennial perennial herb of Compositae. The plant of Jerusalem artichoke is relatively high, but the main edible part is underground tuber. The underground tuber of Jerusalem artichoke is rich in nutrients, with starch, inulin and other polymers. It is used to cook porridge and stir-fry food, and it is the most common pickle in many places. So how to plant Jerusalem artichoke? Today, the editor has brought you the planting method of Jerusalem artichoke. Let's take a look at it.

1. Land selection and fertilization

Although it is said that Jerusalem artichoke has strong adaptability and can grow normally in most of the soil, we plant it for yield. Therefore, when we choose soil, we should choose places where the soil is soft, rich, deep and high-lying. Because Jerusalem artichoke is more suitable for growing in an arid environment, there is no great requirement for water, and the high terrain is to prevent stagnant water and facilitate drainage. After selecting the land, the soil preparation and fertilization, the base fertilizer can be used farm manure and compound fertilizer, and the amount of fertilizer can be controlled according to the planting area. Do a good job of high beds and drains to facilitate planting management in the planting process.

2. Sowing seeds at the right time

After the soil preparation, choose a reasonable sowing time, the south usually begins to sow before and after Ching Ming Festival, and the general sowing method is the stem sowing. Before sowing, the seed stem should be disinfected and soaked in potassium permanganate solution for 4-5 minutes. When sowing, pay attention to the sowing density, pay attention to the size of the plant, do not plant too dense. Then control the sowing depth according to the nature of the soil, the maximum depth should not exceed 8 cm. Too shallow leads to the lodging of Jerusalem artichoke plants and affects the growth. If it is too deep, the emergence of the stem will be limited and the emergence rate will decrease.

3. Seedling management

The time of germination and emergence of Jerusalem artichoke is relatively long, and it takes about 25-30 days for careful management after sowing. After successful emergence, we should strengthen management and improve the survival rate of seedlings. When the seedlings grow to 8-10 cm, check the weeds in the field and do a good job of weeding. Weeding should not be less than twice in the seedling stage. Weeding can promote the nutrient absorption of Jerusalem artichoke and ensure normal growth. When the Jerusalem artichoke grows up gradually and the plant is higher, the effect of weeds decreases gradually, and only the larger weeds in the field need to be pulled out in the later stage.

4. Field management

In the whole growth period of Jerusalem artichoke, it is also necessary to do a good job of topdressing, the number of times of topdressing should not be less than twice, and compound fertilizer can be used. Although Jerusalem artichoke has different requirements for water, the demand for water is still relatively large during the expansion period, so we should water it in time to promote the growth and yield of Jerusalem artichoke. Then when the Jerusalem artichoke plant grows to 0.8 meters, pick off the top in time, because the flowers and fruits of Jerusalem artichoke do not have much effect, in order to prevent flowers and fruits and tubers from grabbing nutrition, it is necessary to inhibit the growth of flowers and fruits. And the branches that are too long and too dense need to be cut off to enhance the permeability and ensure enough light.

The above is the planting method of Jerusalem artichoke, the planting of Jerusalem artichoke is not very troublesome, but it needs to be managed well. Especially for the prevention and control of diseases and insect pests, it is necessary to ensure that Jerusalem artichoke is in a healthy growth environment to avoid unnecessary losses.
