Can Jerusalem artichoke be grown in the north? A feasibility analysis
Whether Jerusalem artichoke can be grown in the north - clearly this question poses no difficulty at all for Jerusalem artichoke. Jerusalem artichoke is a cold-tolerant and drought-tolerant plant. At the seedling stage, it can endure low temperatures of 1-2 degrees and the light frost brought by early spring.
After it grows up, its mature leaves can endure low temperatures of minus 5 degrees. The strongest part is actually its tubers. In the cold barren sand between minus 40 and 50 degrees, when all the leaves of the Jerusalem artichoke above ground have died off, as long as the tubers are not exposed on the surface of the soil and there is still moisture, once the climate is suitable, it can sprout again.
So in the north around March, the dormant Jerusalem artichoke gradually revives. When the surface temperature is around 10 degrees, it begins to sprout. Around August, the Jerusalem artichoke grows to 2 m tall and begins to flower. Around October, the stems and leaves above ground die naturally, and then the tubers below begin to enter dormancy, repeating cycle after cycle and reproducing forever.
Seeing this, friends must be very delighted - Jerusalem artichoke has no problem at all adapting to the northern environment. So is it difficult to grow? How can you grow Jerusalem artichoke successfully? The editor will now explain it to everyone in detail.
How to grow Jerusalem artichoke
Because of its excellent cold tolerance and drought tolerance, Jerusalem artichoke is not too fussy when choosing soil. You can go ahead and use wasteland or sandy land. The withered stems and leaves of Jerusalem artichoke can also break down into nutrients and improve the soil.
After choosing the soil, you can sow. The sowing depth is about 10 cm. During the seedling stage of Jerusalem artichoke, weeds must be removed to create an environment for the seedlings to develop.
The entire growth period generally requires two fertilizations. For watering, there are four key stages: seedling stage, jointing stage, and bud stage.
During the tuber enlargement stage, unless the drought is especially severe, watering is generally not much needed, but sufficient moisture can increase yield. In winter, when the stems and leaves above ground die naturally, the tubers underground can be harvested.
The above is the editor's introduction to growing Jerusalem artichoke in the north. Growing Jerusalem artichoke in the north is actually quite simple. Friends can give it a try when they have the chance, because its stems and leaves look like chrysanthemum flowers, and growing it at home also has the effect of beautifying the house.
The flowering period and growing environment of Jerusalem artichoke
I. The growing environment of Jerusalem artichoke
1. Drought resistance and wind-sand resistance. Jerusalem artichoke tubers within 30 cm below sandy soil can use the nutrients and moisture they absorb themselves, as well as their strong root system, to grow and develop normally. Therefore, Jerusalem artichoke plays a relatively important role in windbreak and sand fixation, and can be used to improve places with wind-blown sand and poor soil. It is a very good plant for improving the environment.
2. Jerusalem artichoke does not have high requirements for temperature and humidity. Its tubers can still safely pass through the cold winter in a frozen soil layer at -30°C. In early spring, the seedlings can still endure the cold of frost, and after the leaves mature in autumn, they can endure short-term low-temperature environments.
According to relevant research, Jerusalem artichoke can grow well on some land unsuitable for planting other crops, such as high-cold sandy wasteland with low annual accumulated temperature and little precipitation, as long as the tubers are not exposed outside.
3. Jerusalem artichoke can avoid pests and diseases. During its growth process, it does not need management such as fertilizing, spraying, or weeding, saving a large amount of manpower and material resources. Once it grows into a patch, it is difficult for people and livestock to destroy it.
II. The flowering period of Jerusalem artichoke
The flowering period of Jerusalem artichoke is generally from August to September. In northern China, the ground temperature begins to rise in March. After a winter of dormancy, the tubers of Jerusalem artichoke gradually awaken from freezing. When the ground temperature reaches 10°C, they begin to sprout. In early April, the leaves emerge from the ground and begin to grow. During this period, the low nighttime temperatures and late frost have no effect or damage on them.
Under normal circumstances, Jerusalem artichoke begins to flower from late August to early September, when the stems are about 2 m tall. The Jerusalem artichoke flower is pure yellow and has no scent.
Besides having a certain ornamental value and playing an important role in windbreak and sand fixation, Jerusalem artichoke actually also has good medicinal value. Next, let us discuss together what edible and medicinal values Jerusalem artichoke has in terms of medicinal use.
