What are the key points to note when growing Jerusalem artichoke? These few points are crucial

Jerusalem artichoke belongs to the Asteraceae family and is also called "devil's ginger" by some. It is a new type of plant introduced to China from Europe, with its place of origin in North America. The main usable part is its underground tubers, which resemble the common ginger in shape. It is mainly used to make starch and alcohol, and secondly it can also be eaten, and it can also be grown as an ornamental plant. Below let us take a look at what needs to be noted when growing Jerusalem artichoke.

1. Soil

Jerusalem artichoke has strong adaptability to the growing environment, but when choosing soil, attention still needs to be paid to the choice of soil texture. The main thing to note is the issue of soil pH. So when selecting a site, a pH test should be done; acidic soil cannot be used to grow Jerusalem artichoke. Next, saline-alkali land and marshland also cannot be used to grow Jerusalem artichoke. Other cropland and plots where crops cannot be grown can all be used to grow Jerusalem artichoke.

2. Temperature

The growing temperature is also something we need to pay special attention to. Jerusalem artichoke prefers cool and dry conditions, and its cold resistance and drought resistance are both fairly good. Generally, it sprouts when the temperature is around six degrees, and once the temperature rises slightly to around ten degrees, it can emerge. When the temperature is around fifteen to twenty-five degrees, the tubers of Jerusalem artichoke grow relatively fast, so throughout its entire growth process we must accurately grasp its requirements for growing temperature.

3. Sowing

Sowing mainly uses tuber propagation, generally by hole sowing or drill sowing. When planting, the planting density should be planned well; the row spacing and plant spacing are about fifty cm. When sowing, also note that the end of the tuber with the bud point should face upward, and the sowing depth is about ten cm. Finally, cover with soil to bury the seed and then wait for emergence.

4. Fertilizer and water

In addition to the base fertilizer, generally two additional fertilizations are needed during its growth process. The first fertilization is around May, that is, when the Jerusalem artichoke seedlings have grown to roughly fifteen to twenty cm. At this time, urea is mainly used to promote the growth of the seedlings and make them grow more new branches. The second additional fertilization is when Jerusalem artichoke begins to form buds, mainly using potassium fertilizer to promote tuber growth. Jerusalem artichoke prefers dry conditions, and watering is generally done only at fixed times, namely the seedling stage, jointing stage, early bud stage, and tuber enlargement stage.

5. Topping

Topping is also a very important step in the growth process of Jerusalem artichoke. When Jerusalem artichoke forms buds, we need to properly remove its flower buds at this time, as this can promote the growth of the Jerusalem artichoke tubers. If the buds are not removed in time when Jerusalem artichoke buds, it will cause excessive growth of branches and leaves, nutrients will be absorbed by the branches and leaves, and the tubers will develop poorly. Therefore, in order to increase the yield of Jerusalem artichoke, this is also something worth our attention.

The above is all the content the editor wants to share with you about the points to note when growing Jerusalem artichoke. In the process of growing Jerusalem artichoke, be sure to pay attention to these rather detailed things, so that the yield and quality of the Jerusalem artichoke grown will be better.
