A Detailed Explanation of the Latest Points to Note When Growing Jerusalem Artichoke
Jerusalem artichoke belongs to the Asteraceae family and is also called "guizi jiang." It is a new type of plant introduced to China from Europe, and its place of origin is North America. The main usable part is its underground tuber, which resembles the ginger we commonly see, and it is mainly used to make starch and alcohol. Second, it can also be eaten, and it can also be grown as an ornamental plant. Now let us take a look at what needs attention when growing Jerusalem artichoke.
1. Soil
Jerusalem artichoke is highly adaptable to the growing environment, but when choosing soil, attention still needs to be paid to the choice of soil quality. 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 crop-growing land 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 6 degrees, and once the temperature rises slightly to around 10 degrees, it can emerge. When the temperature is around 15 to 25 degrees, the tubers of Jerusalem artichoke grow relatively quickly, so throughout its entire growth process we must accurately grasp its temperature requirements for growth.
3. Sowing
Sowing is mainly done through tuber propagation, generally using hole sowing or drill sowing. When planting, the planting density must be planned well, with row spacing and plant spacing at about 50 cm. When sowing, note also that the end of the tuber with the bud point should face upward. The sowing depth is about 10 cm. Finally, cover with soil to bury the seed, then wait for emergence.
4. Fertilizer and Water
In addition to 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 about 15 to 20 cm, and at this time it is mainly urea, to promote seedling growth and make it grow more new branches. The second additional fertilization is when Jerusalem artichoke begins to form buds, and it is mainly 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. Pinching Off the Top
Pinching off the top 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, which can promote the growth of the Jerusalem artichoke tubers. If the buds are not removed in time when Jerusalem artichoke buds, this will cause excessive growth of branches and leaves, nutrients will be absorbed by the branches and leaves, and tuber growth and development will be poor. 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 everyone about the points to note when growing Jerusalem artichoke. In the process of growing Jerusalem artichoke, be sure to pay attention to these more detailed matters, so that the yield and quality of the Jerusalem artichoke grown will be better.
