How to grow celery in winter? Here comes the latest planting technique and method tutorial

Celery is a vegetable that many people enjoy eating very much, and it has a relatively large market demand in all parts of our country. Celery cultivation is relatively simple, and under normal circumstances the yield is very good. Celery is generally best planted in autumn, and when it enters winter, the temperature is very low. So how should we grow celery in winter? Below, the editor brings you the winter cultivation techniques for celery, let's take a look!

1. Sowing and raising seedlings

In August each year, do the seed collection work well and carry out sowing in stages, with November to March being the supply period. First, we must prepare the seedling bed well, ensuring the seedling bed soil is loose, has good permeability, and drains and irrigates normally. Then apply sufficient farmyard manure as base fertilizer, and level and finely break up the soil. Then treat the seeds well and do the work of soaking the seeds to promote germination. Then water the seedling bed thoroughly, maintain good soil moisture, and sow at the right time. After uniform sowing, cover with a layer of fine soil, and do the management work well during the seedling stage to ensure the seeds can germinate and emerge normally.

2. Land preparation and planting

When growing celery in a greenhouse in winter, the growth period of celery is relatively long, but the yield is also relatively high, so the demand for nutrients is very great. Therefore, before planting, we must do the work of land preparation and deep plowing well, applying about 4500kg of decomposed farmyard manure per mu, together with an appropriate amount of superphosphate, and plow it into the soil. Different varieties of celery also have different growth periods. Therefore, the seedling age for transplanting must be determined according to the variety. Before planting, pour sufficient water into the seedling bed to ensure the seedling roots can fully contact the soil and improve the survival rate after planting. Finally, when planting, transplanting with soil should be the main method to avoid damage to the seedling roots.

3. Management after planting

In winter the temperature is very low, so after planting, the first thing we must do is the work of covering the greenhouse to keep the seedlings warm. However, the temperature should not be too high either; if it exceeds 20 degrees, it will cause poor growth of celery. The lowest temperature must not be below zero degrees, as it is prone to frost damage. Then do the fertilizer and water work well, usually watering once about every three days, and appropriately topdressing after the seedlings have recovered. Then one month after planting, to provide sufficient nutrients for the growth of new roots and new leaves of celery, apply about 18kg of nitrogen-phosphorus-potassium fertilizer to avoid malnutrition of the seedlings.

4. Harvesting and storage

Celery can be harvested when it grows to about 65 cm, and the specific time can be determined according to the market and the planting season. Harvesting can be done all at once or in multiple harvests. After the heart of the celery plant is filled out, it should be harvested in time, otherwise the celery is prone to hollowing and cracking. The harvesting method is mainly cutting at ground level, keeping the base and leaf stalks from separating, and after removing yellow leaves and soil it can be marketed. There are many storage methods for celery. Generally, in areas where winter is not very cold, the deep trench temporary planting method can be used for storage. In colder areas, greenhouses, vertical trenches, etc. need to be used for temporary planting.

The above is a brief introduction to the winter cultivation techniques for celery. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
