The Latest Celery Seedling Raising Methods and Techniques Explained in Detail
Celery is a vegetable side dish that many people enjoy eating very much, and it has a wide planting area in our country. The root system of celery is distributed rather shallowly, and its nutrient absorption capacity is relatively weak. Therefore, when planting celery, seedlings are generally raised first to improve the growth capacity of the seedlings, promote robust growth, effectively increase yield, and enhance quality. So how should celery seedlings be raised? Below, the editor brings you the seedling raising techniques for celery. Let's take a look together!
1. Seedbed Preparation
If greenhouse seedling raising is used, then a leeward, sunny spot must be chosen to make the seedling bed well. The seedling bed should not be too large, so as to reduce land waste and make watering convenient. After leveling and making the bed, apply sufficient base fertilizer to the seedling bed. The base fertilizer must be fully mixed with the soil, plowed with the soil to a depth of 10 cm, and the soil finely leveled and broken up. After soil preparation and fertilization, build good shading measures on the seedling bed, so as to prevent direct sunlight from affecting seed germination after sowing. Then prepare fine soil and fine sand around it, so that after sowing they can be covered over the seeds to improve the soil's heat preservation and moisture retention capacity.
2. Seed Soaking and Germination Promotion
According to the size of the seedling bed, prepare an appropriate amount of seeds. Then soak the seeds in warm water for one day, then take them out and rinse them with clean water 3-4 times. When rinsing, rub and knead the seeds to rub open the seed coat. Then place them in the sun to dry the seeds. When the seeds are in a half-dry, half-moist state, wrap them with a wet cloth and bury them in a clay pot, then water the clay pot thoroughly. Place the clay pot at a temperature of about 19 degrees to promote germination. During the germination promotion process, turn the seeds twice at regular intervals to ensure even germination, and keep the soil moist. Generally, they will sprout in about a week.
3. Sowing Time
The specific sowing time for celery seeds must be decided according to the planting region and season. For example, if cultivating and sowing in spring, it is generally around early November. Once winter arrives, good covering and freeze prevention work must be done. When sowing, pay attention to the sowing amount and sowing density, and do not sow too densely. Before sowing, first water thoroughly. After the water has seeped down into the seedling bed, then sow appropriately. After sowing, promptly cover with the previously prepared fine soil and fine sand, then cover with a layer of plastic film to improve the soil's capacity. After sowing, do good management work, strengthen weed control, and improve the seed germination rate.
4. Seedling Stage Management
After sowing, in order to prevent weeds from competing for the nutrients needed for seed germination, appropriately use herbicide for weed control. If there are weeds that have not been killed by the herbicide, promptly pull them out by hand. After the seedlings break through the soil, uncover the plastic film and water promptly, and afterward keep the soil evenly dry and moist. If air humidity is high and ventilation is insufficient, pay attention to the watering amount to prevent celery diseases and insect pests. When the seedlings are weak in growth and lack nutrients, promptly apply additional fertilizer. Urea can be washed in with water, and can also be appropriately sprayed onto the leaf surface. In addition, during the seedling stage, thinning must be done at least twice. The first time is after the seedlings break through the soil, and then thinning is done again when the seedlings grow to 2 true leaves. Thinning follows the principle of keeping the strong and removing the weak.
After the seedlings emerge, the management work for the seedlings must be strengthened, because the seedling stage of celery is relatively long. Therefore, when raising seedlings, its management work is very important. Generally, when the seedlings have grown for about 45 days, they can be planted out. When planting out, pay attention to doing the preparation work for the field to be planted well, and when transplanting, prevent damaging the roots of the seedlings, which would affect the normal growth of celery. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
