The latest planting method of alpinia officinalis

Jerusalem artichoke is a perennial perennial herbaceous plant, which has a very large planting area in China. The main edible part is the underground rhizome, which can be cooked and pickled, and can also be dried into dried ginger, which is very popular in China. Jerusalem artichoke also has a high medicinal value, can treat nameless swelling poison, mumps and so on. So how should ginger be grown? The following small series brings you the cultivation method of Jerusalem artichoke. Let's take a look together!

1. Environmental requirements

Jerusalem artichoke likes to grow in cool and dry environments and has strong cold and drought tolerance. At temperatures of about 5 degrees, tubers begin to germinate, and seedlings can emerge at about 10 degrees. The adaptability of Jerusalem artichoke to soil is relatively strong, but if you want to improve the yield of Jerusalem artichoke, then try to ensure the quality of soil. Soil PH value should not be too acidic, to ensure that the soil has a strong permeability, soft and good irrigation capacity. Then we should do a good job of soil preparation. If the soil is of high quality, it is very beneficial to the yield and quality of Jerusalem artichoke.

2. Seed preparation

The propagation method of Jerusalem artichoke is mainly fast stem propagation, and it is generally harvested in autumn and winter every year. After the tuber is harvested, the tuber weighing about 22g should be selected as the seed stem and stored in sand for seed. It is also possible to select tubers of appropriate size for sowing after the soil temperature rises in spring. Spring is usually the best time for sowing Jerusalem artichoke, and the sowing method is hole sowing or furrow sowing. When sowing, we should control the sowing density, plant spacing control in 50cm or so, dig loose soil after applying appropriate amount of base fertilizer, base fertilizer should not be too much, avoid fertilizer damage. Then it can be sown in due time, sowing should not be too deep, keep it at about 10cm, cover fine soil after sowing, and level the sowing hole.

3. Field management

The emergence time of Jerusalem artichoke is relatively fast, generally about a month after sowing can emerge. Pay attention to watering and fertilizing after the seedlings of Jerusalem artichoke are complete, strengthen intertillage and weeding, and then cultivate the field into low ridges. If the soil moisture content is not very dry, then do not water again. Keep the soil dry and wet until the tuber expands. If the stems and leaves of the above-ground part grow too vigorously, then we should do a good job of topping, concentrating nutrients on tubers and promoting expansion.

4. Timely harvest

The disease resistance of Jerusalem artichoke is very strong, and diseases rarely occur during its growth, so it is basically unnecessary to use pesticides. However, it is occasionally damaged by aphids, which can be eliminated by spraying water after occurrence. The harvest time of Jerusalem artichoke is generally after the autumn frost of each year. When harvesting, the tubers are dug out directly, and then the soil on the tubers can be washed clean before they can be listed. If seed is to be saved, select a few small tubers and bury them in the soil at harvest time. The seedlings can emerge in the second year, and then the work of thinning and replenishing seedlings must be done well.

The above is a simple introduction to the cultivation method of Jerusalem artichoke. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
