The texture of Jerusalem artichoke is delicate and smooth, and the taste is crisp and aromatic. It can be eaten raw, stir-fried or pickled in sauce. It is widely favored by customers and has a very bright industry prospect. Therefore, according to the quality and characteristics of Jerusalem artichoke, growers can make full use of local ecological resources such as light, heat, water, and soil, vigorously introduce Jerusalem artichoke for planting, and use effective planting techniques to continuously improve the production, sales, and quality of Jerusalem artichoke. . Jerusalem artichoke is a perennial woody plant belonging to the genus Helianthus of the Asteraceae family. The stem is long and straight, usually oblate, with a stem thickness of 2.0-3.0cm, with irregular protrusions on both sides, and branches growing from the base of the stem; the leaves are not smooth, with serrated edges, and the back is plush and irregular. The multi-spherical underground rhizome is generally spindle-shaped and is the main edible part.
Jerusalem artichoke is grown year-round in China and has strong drought and low temperature tolerance. Generally, Jerusalem artichoke can grow normally at temperatures between -20-35°C, with an average annual rainfall of more than 100mm. It can be planted in any place; Jerusalem artichoke has a very strong breeding ability, and seeds can germinate normally from a soil depth of more than 50cm, and can rapidly expand and grow; Jerusalem artichoke rhizomes are very developed and can maintain moisture. It has a strong working ability and is most suitable for planting in sandy soil layers to improve the fertility of the soil. Applying sufficient base fertilizer can ensure the total amount and size of Jerusalem artichoke underground rhizomes, which has the actual effect of making farmers rich.
The rhizomes of Jerusalem artichoke can be harvested after the leaves and stems of Jerusalem artichoke generally turn yellow on a large scale. Moderate harvesting can increase the production, sales and quality of Jerusalem artichoke to a certain extent. Choose clear skies and warm temperatures for harvesting. Collect fresh Jerusalem artichoke rhizomes with zero pollution, no mold, no fine sand, and good quality. Avoid long-term exposure of the tubers to the sun and reduce cleaning. You can seal the bags immediately after harvesting. Handle it with care to reduce damage to the rhizome and prevent the rhizome from becoming moldy and deteriorating in quality, which is beneficial to the later storage and transportation of Jerusalem artichoke. Jerusalem artichoke prefers warm climate conditions. The rhizomes of the plant can germinate at 6-8 degrees Celsius. 8-12 degrees is the most suitable environmental temperature for Jerusalem artichoke to germinate. In the case of severe cold in spring, the seedlings can withstand freezing damage at zero degrees and will not be cracked by freezing even at minus 25-35 degrees.
Of course, hot weather is extremely detrimental to the growth of Jerusalem artichokes. The most suitable temperature for Jerusalem artichoke rhizomes to grow is 18-22 degrees. If the temperature difference between day and night is relatively large, it will be beneficial to the sufficient accumulation of Jerusalem artichoke dry matter. Jerusalem artichoke has strong drought resistance because its rhizomes are large and can use water in deep soil layers. The thick stems of Jerusalem artichoke have the ability to store water. In the case of drought, the plant can use this part of the water to maintain life; the surface of the leaves of Jerusalem artichoke plants are covered with hairs, which can regulate their own evaporation and prevent hot and dry winds. effect. At the same time, water plays a key role in the growth and development of Jerusalem artichokes and in increasing high-quality yields. Because the Jerusalem artichoke plant can only complete normal human physiological activities when it has sufficient water content.
