How to raise seedlings of the latest celery

Celery is a kind of vegetable side dish that many people like to eat very much. it has a wide planting area in China, the root distribution of celery is shallow, and its nutrient absorption capacity is relatively weak. Therefore, when planting celery, it is generally necessary to raise seedlings first to improve the growth ability of seedlings and promote robust growth, which can effectively increase yield and enhance quality. So how to raise celery seedlings? The following editor has brought the seedling technology of celery, let's have a look!

1. Seedbed preparation

If the greenhouse is used to raise seedlings, then it is necessary to choose the leeward and sunny place to make the seedling bed, which should not be too large, reduce the waste of land and facilitate watering. After leveling the bed, apply sufficient base fertilizer on the seedling bed, which should be fully mixed with the soil, plough it with the soil for 10 cm, and finely crush the soil. Shading measures should be built on the seedling bed after soil preparation and fertilization, so as to prevent direct sunlight from affecting seed germination after sowing. Then prepare fine soil and fine sand around so that it can be covered on the seeds after sowing, so as to improve the heat preservation and moisture retention capacity of the soil.

2. Soaking seeds to accelerate germination

Prepare the right amount of seeds according to the size of the nursery bed. Then soak the seeds in warm water for one day, then remove them and wash them with clean water for 3-4 times. Knead the seeds and knead the seed coat when cleaning. Then dry the seeds in the sun. When the seeds are semi-dry and semi-wet, wrap them in a wet cloth and bury them in a mud basin, then pour the mud basin thoroughly. Put the mud basin at a temperature of about 19 degrees to promote germination, and in the process of accelerating germination, the seeds should be turned twice regularly to ensure that the seeds are uniformly germinated, and to keep the soil moist, it will sprout in about a week.

3. Sowing time

The specific planting time of celery seeds should be determined according to the planting area and season. For example, if sowing in spring, it is usually around the beginning of November. If you enter winter, you should do a good job of covering and anti-freezing. When sowing, pay attention to the sowing rate and density, do not sow too dense. Before sowing, you should first pour enough water, and when the water seeps into the seedbed, sow the seeds properly. After sowing, it is necessary to cover the prepared fine soil and sand in time, and then cover with a layer of plastic film to improve the ability of the soil. After sowing, we should do a good job in management, strengthen weeding and improve the germination rate of seeds.

4. Seedling stage management

In order to prevent weeds from grabbing the germination nutrition of seeds after sowing, herbicides should be properly used to control weeds. If weeds are not killed by herbicides, they should be pulled out manually in time. After breaking the soil, the seedlings were uncovered with plastic film and watered in time to keep the soil dry and wet evenly. If the air humidity is high and the ventilation is insufficient, we should pay attention to the amount of water to prevent celery diseases and insect pests. When the seedlings are weak and lack of nutrition, fertilizer should be applied in time. Urea can be properly sprayed to the leaf surface when washed with water. And at least twice in the seedling stage, the first time after the seedlings break the soil, and then when the seedlings grow to 2 true leaves, the seedlings should be strong and weak.

After the seedlings are unearthed, it is necessary to strengthen the management of seedlings, because the seedling stage of celery is relatively long, so when raising seedlings, its management is very important. Generally, the seedlings can be planted when they grow to about 45 days. When planting, we should pay attention to the arrangement of the field, and prevent damage to the roots of the seedlings and affect the normal growth of celery when transplanting. That's all for today's introduction. This article is for reference only. I hope it can help you all.
