How and when to plant overwintering shallots

Overwintering shallots are planted in a variety of ways: planting time, heat retention treatment, and field management.

1. Planting time.

Overwintering shallots should be planted around October every year, and the planting should be done on a flat and well-drained plot with fertile soil. Overwintering shallots do not require high soil pH, but slightly alkaline soil will be more conducive to the growth of shallots. Before sowing, the land should be turned deep and the plantar fertilizer should be applied.

2. Thermal insulation treatment.

When planting overwintering shallots, its thermal insulation measures are very important, the easiest way is to plant the shallot seeds, cover some straw on the ground for heat preservation, but this insulation method, the shallot can only emerge after the spring of the second year, and the market time is relatively late.

3. Field management.

The root system of shallots is relatively shallow, and it is not suitable to apply thick fertilizer during the growth period, and the urea should be diluted into fertilizer water when topdressing, and then applied, in addition to the weeds in the field should be removed in time during the growth of overwintering shallots, and special attention should be paid to watering when watering.

Green onions

Allium is a perennial herbaceous plant of the family Liliaceae. Bulbs solitary, cylindrical, sparsely ovate-cylindrical with an expanded base; The bulb has a white, pale reddish-brown skin, membranous to thin leathery, and does not break. Leaves cylindrical, hollow; The pediments are cylindrical, hollow, swelling below the middle and narrowing towards the apex.

Green onions originate in semi-cold regions and prefer cold and are not tolerant of heat. Native to China, it is widely cultivated throughout China and also abroad.

1. Winter shallots are best sown and planted in October every year, adjust the time according to the local climate, if the temperature is low in the area, you can choose to sow in early October, and the southern region with high temperature can be sown in late October. If the sowing time is early, it will suffer from low temperature and cause leaf death, if the sowing time is late, it will make the seedlings smaller, resulting in poor root development and easy death.

2. Tidy up the soil, choose to plant in the sun, you can choose the sandy soil with strong water and fertilizer absorption, the soil is required to be acidic, if the soil is alkaline, you can add pentachloronitrobenzene, methyl bromide, etc. to adjust the acidity and alkalinity of the soil, so as to promote the soil to maintain a reasonable pH value. Combined with deep ploughing and application of well-rotted farmhouse fertilizer, keep the soil loose and fertile, and do not choose the soil where onions and garlic are planted in the previous crop.

3. Seed treatment, before planting green onions in winter, prepare the seeds first, you can determine the desired variety, and then select a new seed that is full, full, and free of diseases and pests, and can not choose the old seed, otherwise the germination rate will be reduced. Before sowing, prepare 55 minutes of warm water, soak the seeds for about 20 minutes, and then remove them to dry before sowing.

1. Sow the onion seeds in mid to late June, and transplant the green onion seedlings to the field from mid-August to early September.

2. Conventional green onion cultivation is sown in March and harvested in October. In this way, before the green onion harvest in the next year, only the market can be dried onions. In some areas, farmers sow the onion seeds in mid-to-late June, transplant the onion seedlings to the field from mid-August to early September, and after a winter, return to green around mid-March of the following year, and harvest fresh onions for sale from the end of April to early May.

3. In this way, it is not only staggered with the autumn harvest of green onions, but also can alleviate the contradiction between the off-peak season in the market, and can increase income.

1. Autumn planting time: sowing in early September in the autumn of the first year, overwintering with seedlings, planting in early to mid-May in the summer of the second year, harvesting before winter, overwintering in the cellar or open field, flowering in the spring of the third year, and harvesting seeds in the second season.

Seedlings can be marketed as shallots from early May to late June. It can also be planted in flat furrows before and after the beginning of summer (pinching onions) or narrowed row spacing to plant into ditch shallots as autumn shallots**, or as early spring onions after wintering**.

2. Spring planting time: sowing after thawing the soil in early spring, as shallot** before the arrival of hot summer, or harvesting as dry onion or ditch onion ** in the year after planting. It can also be overwintered as a sage or as a seed plant.

3. Summer planting time: mostly sown in late July to early August, so it is also known as onion. The plants are larger when they overwinter that year. It is easy to complete the vernalization process, and the next spring germinates early and blooms quickly. Generally, it is marketed after receiving the horn onion.
