Culture methods of scallions

Large scallions, also known as Ji'an flowers, giant onions, high onions, scallions, etc., are perennial bulb flowers of the Liliaceae, native to Central Asia and the Mediterranean region. China is mainly distributed in the northern region, as a flower border, rock garden or lawn side decoration and beautification of varieties, with high ornamental value, let's take a look at the breeding methods of scallions!

Growth habits of scallions

Scallions originated from Central Asia and the Mediterranean region, mainly concentrated in the north of China, flowering in spring and summer, like cool and sunny environment, avoid damp, hot and rainy, avoid continuous cropping, semi-shade, suitable temperature 15-25 ℃, loose and fertile sandy soil, avoid stagnant water, suitable for cultivation in the north of China.

Propagation methods of scallions

1. Seed propagation: the seeds of scallions were collected and dried in the first ten days of July, stored at 5-7 ℃, sowed in autumn from September to October, and germinated in March of the following year. In summer, the upper part also withered and formed small bulbs, and the sowing seedlings needed about 5 years to blossom.

2. Ramet propagation: the bulbs around the main bulb were peeled in summer and autumn, and the sandy soil with low groundwater level, good drainage, loose and fertile sandy soil was selected as the cultivation land. each female ball can be divided into 1-3 small balls, among which the larger bulbs can bloom in the second year after planting.

Culture methods of scallions

The main results are as follows: 1. Scallions are a kind of flowers with very low natural proliferation rate of bulbs, but if they are removed as soon as possible after the appearance of scape, so that nutrients are concentrated on the development of regeneration bulbs and bulbs, the number of bulbs can be increased appropriately. If the aboveground part dies in summer, the bulbs can be dug out, large and small bulbs can be separated, and the ventilated place can be put over the summer.

2. Large scallions are planted after autumn. Those whose bulbs are more than 3 centimeters can blossom after planting, and those less than 3 centimeters need to be cultivated for one year before they can blossom. Bulbs proliferate in a cool and sunny environment, requiring loose and fertile sandy soil and avoiding stagnant water. It is suitable for cultivation in the north of China.

3. For open field cultivation of scallions, sandy soil with low groundwater level, good drainage, loose and fertile soil should be selected as cultivation land. the time of planting bulbs should be from mid-late September to early October, and the row spacing is 20 × 30 cm. The depth of planting is that the thickness of the overlying soil on the bulb is 2 / 3 times that of the fresh stem.

4. After planting, scallions are slightly pressed to level the cave surface, and then watered so that they do not need to be covered against cold in winter. When the leaves are unearthed in March of the following spring, loosen the soil and water in time, cooperate with liquid topdressing and water once every 10-15 days, pay attention to ploughing, loosening soil, weeding and adding a small amount of artificial spray or shade in dry places, which can ease the change of withered and yellow leaves in early summer.

5. The stems and leaves withered after the onion blossoms, and the bulbs should be dug up as early as possible before the rainy season, so as not to rot after the rain, put them away in a ventilated and dry place and put them away in an indoor ventilated place. They should be planted in 9 ~ 10 months, and the planting land should not be planted continuously. Pay attention to the application of rotten organic fertilizer. It is rainy in summer and needs timely drainage. Scallions are named because of their large inflorescences.
