What are the environmental requirements for Welsh onion? The latest key growing points

Welsh onion is an indispensable side vegetable in our daily lives; adding a little scallion when cooking can enhance the aroma of a dish. It is grown all over our country, but some yields are less than satisfactory, because many friends do not manage the growing environment well when growing it. For example, light, soil, temperature and so on; these factors are very important to the growth of Welsh onion. So what are the environmental requirements when growing Welsh onion? Let's take a look together!

1. Temperature

The growth of Welsh onion has a strong ability to adapt to temperature, and it can grow normally under both high and low temperatures. But if you want to achieve high yields, you still need to keep the temperature within the range most suitable for the growth of Welsh onion. For example, the most suitable temperature for Welsh onion germination is around 20 degrees; if this temperature is controlled well, Welsh onion can germinate in no more than 3 days. The leaf growth temperature is around 20 degrees, while the white scallion part is around 15 degrees, which is beneficial to the growth of Welsh onion and increases yield.

2. Light

Welsh onion is not strict about light; it is enough to keep light intensity and duration at a moderate level every day. This is because the leaves of Welsh onion are different from those of other crops: the scallion leaves are cylindrical, so even if planted densely, most Welsh onion plants can still get enough light. In addition, the growth of Welsh onion is not suited to strong light; strong light will cause Welsh onion to age prematurely, reduce quality, and in severe cases lose its commercial value.

3. Water

Welsh onion has relatively few roots, and its ability to absorb fertilizer and water is not very strong; generally, the roots of Welsh onion are in the shallow layer. It has relatively high water requirements, and during the growing process the soil needs to be kept in a moist state. However, although Welsh onion likes water, it is not tolerant of waterlogging. If there is too much standing water in the field and it is not drained in time, Welsh onion is very prone to waterlogging damage; the roots cannot breathe, begin to rot, and eventually die.

4. Soil

A soil pH of around 7 is the acidity and alkalinity level most suitable for the growth of Welsh onion. Fertile soil with a loose texture and strong water- and fertilizer-holding capacity is beneficial for promoting the germination and emergence of Welsh onion and enhancing the nutrient absorption capacity of the roots. After emergence, the soil should be kept in a loose state; soil compaction will reduce the growth rate of Welsh onion, or even stop its growth. Half a month before transplanting, control the watering frequency to prevent lodging later on.

5. Fertilizer

Welsh onion needs a large amount of nutrients throughout its entire growth period; its fertilizer requirement is also relatively large, and the nutrients it needs are relatively broad. During the seedling stage, nitrogen fertilizer should be emphasized, but it should not be applied excessively or in a one-sided way. At the mature stage, the focus of fertilization needs to shift to phosphorus and potassium; if Welsh onion lacks phosphorus, it will affect its growth and reduce yield. Attention should also be paid to the supplementation of some trace elements; supplementary application of trace elements is the key to increasing yield.

The above is a brief introduction to the environment needed for growing Welsh onion. Growing Welsh onion is very easy, but everyone needs to manage it well to ensure normal growth of Welsh onion. When harvesting, everyone should note: do not pull Welsh onion up by the roots; use a knife or scissors to cut above the roots, and new scallions will still grow from the roots afterward. That is all for today's introduction. This article is for reference only, and we hope it is helpful to everyone.
