How to Grow Jerusalem Artichoke? A Complete Guide to the Latest Planting Methods
Jerusalem artichoke is a perennial herbaceous plant with persistent roots belonging to the Asteraceae family. The Jerusalem artichoke plant is relatively tall, but the main edible part is the underground tuber. The underground tubers of Jerusalem artichoke are rich in nutrients, containing starch, inulin and other polymers. They are used for making porridge and stir-frying, and are also the most common pickled vegetable in many places. So how should Jerusalem artichoke be planted? Today, the editor brings you the planting methods for Jerusalem artichoke. Let's take a look below!
1. Site Selection and Fertilization
Although Jerusalem artichoke has relatively strong adaptability and can grow normally in most soils, we plant it for yield. Therefore, when choosing soil, we should choose a place with soft, fertile, deep soil and higher terrain. This is because Jerusalem artichoke is relatively suited to growing in dry environments and has no great demand for water; higher terrain is to prevent water accumulation and facilitate drainage. After selecting the site, prepare the land and apply fertilizer. Farmyard manure and compound fertilizer can be used as base fertilizer, and the fertilizer amount should be controlled according to the planting area. Make raised beds and drainage ditches to facilitate planting management during the growing process.
2. Timely Sowing
After preparing the land, choose a reasonable sowing time. In the south, sowing usually starts around Qingming Festival, and the general sowing method is seed tuber sowing. Before sowing, do a good job of disinfecting the seed tubers by soaking them in potassium permanganate solution for 4-5 minutes. When sowing, pay attention to the sowing density and the size of the plants; do not plant too densely. Then control the sowing depth according to the nature of the soil, and the deepest should not exceed 8 cm. Too shallow will make the Jerusalem artichoke plants prone to lodging and affect growth, while too deep will restrict the seed tubers from emerging through the soil and reduce the emergence rate.
3. Seedling Management
The germination and emergence time of Jerusalem artichoke is relatively long. With careful management after sowing, it takes about 25-30 days to emerge through the soil. After successful emergence, we should strengthen management to improve the survival rate of the seedlings. When the seedlings grow to 8-10 cm, check the weed situation in the field and do a good job of weeding. During the seedling stage, weeding must be done no fewer than two times. Weeding can promote nutrient absorption by Jerusalem artichoke and ensure normal growth. When Jerusalem artichoke gradually grows larger and the plants are taller, the impact of weeds gradually decreases. In the later stage, it is only necessary to pull out the larger weeds in the field.
4. Field Management
During the entire growth period of Jerusalem artichoke, topdressing should also be done well, and the number of topdressings should be no fewer than two. Compound fertilizer can be used. Although Jerusalem artichoke has different water requirements, during the tuber expansion period, its demand for water is still relatively large. Therefore, during the expansion period, we should water in time to promote the growth of Jerusalem artichoke and increase yield. Then, when the Jerusalem artichoke plants grow to 0.8 m, remove the growing tips in time. This is because the flowers and fruits of Jerusalem artichoke do not have much use, and in order to prevent the flowers and fruits from competing with the tubers for nutrients, the growth of flowers and fruits should be inhibited. It is also necessary to prune overly long and dense branches to enhance air circulation and light penetration and ensure sufficient sunlight.
The above are the planting methods for Jerusalem artichoke. Planting Jerusalem artichoke is not very troublesome, but management needs to be done well. In particular, the prevention and control of pests and diseases should ensure that Jerusalem artichoke is in a healthy growing environment and avoid unnecessary losses.
