How to Grow Welsh Onions? Latest Planting Techniques and Method Tutorial
The Welsh onion is a biennial plant of the Liliaceae family, and there are now a great many varieties of Welsh onion in our country. Market demand is greatest in the northwest region, and the Welsh onion holds a pivotal position among vegetables in our country, with its planting area reaching 1/10 of the total vegetable area, and its economic benefits are relatively high. So how should Welsh onion cultivation be done? Below, the editor brings you the cultivation techniques for Welsh onions, let's take a look!
1. Site Selection and Land Preparation
The root growth ability of the Welsh onion is relatively weak, and when soil is hilled up during planting, the distribution is relatively deep. Therefore, ensuring the soil is sufficiently permeable is something we need to pay attention to when planting. We must ensure the planting soil is sufficiently deep and highly permeable. In many places, the Welsh onion yield is insufficient mainly because the soil layer is too shallow, causing the Welsh onion roots to extend beyond the plow layer, which affects growth and leads to severe pest and disease damage. So after selecting the land, we must deep-plow it at least about 30 cm to improve soil permeability, and then apply sufficient base fertilizer, mainly decomposed farmyard manure.
2. Sowing and Raising Seedlings
Welsh onion seeds are relatively small, and the seed coat is relatively hard, so the growth rate of Welsh onion seedlings during the seedling stage is relatively slow. Therefore, before sowing, we should finely prepare and level the seedling bed, water it thoroughly, and once the water has seeped into the soil, broadcast the seeds evenly over the entire area. After sowing, cover with soil and plastic film to improve the soil's heat and moisture retention capacity. After sowing, keep the temperature at around 20 degrees, and seedlings will emerge in about a week. When half the seeds have emerged, remove the plastic film; this must not be done too late, otherwise it will reduce the vigor of the seedlings. Water once after the seedlings have spread out, and then water appropriately according to soil moisture conditions. Do not water too much, to prevent the soil... throughout the entire seedling period, topdressing about twice is needed.
3. Timely Hilling of Soil
Hilling soil is very important for the growth of Welsh onions, and generally it needs to be done after watering and fertilizing. Control the intensity according to the growth time of the Welsh onion; in the early stage, do not hill the soil too tightly, as this reduces soil permeability. This can easily lead to undesirable phenomena such as thin and weak white stalk bases and dead seedlings, reducing the commercial value of the Welsh onion. During the Welsh onion growing period, soil should be hilled at least about 5 times, and the last time is to improve the Welsh onion's wind resistance and prevent lodging. After hilling, also pay attention to disease prevention work, enhance the Welsh onion's disease resistance, and avoid pest and disease damage.
4. Field Management
Water and fertilizer are indispensable substances in the Welsh onion's growth process, and although they are relatively important, attention must also be paid to the amounts; too much fertilizer can easily cause fertilizer damage to the Welsh onion and reduce yield. Too much water is the same, easily causing root rot in the Welsh onion and triggering various pests and diseases. We should carry out water and fertilizer work reasonably according to soil conditions, weather and the actual growth situation of the Welsh onion. Finally, the harvest time should be determined according to the Welsh onion variety planted; if early-maturing varieties are harvested too late, it can easily cause frost damage to the Welsh onion, while conversely, if late-maturing varieties are harvested too early, it will affect yield.
The above is a brief introduction to Welsh onion cultivation techniques; the cultivation techniques for Welsh onions are relatively simple. They are also relatively extensive to manage, but attention must still be paid to pest and disease control work. Otherwise, it will have a great impact on yield and quality, reducing planting benefits.
