Introduction to the technology of accelerating germination and raising seedlings of celery!

The root distribution of celery is shallow, and its nutrient absorption capacity is relatively weak, so 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. the following is the introduction of the technology of accelerating germination and raising seedlings of celery!

First, 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 bottom fertilizer on the seedling bed, which should be fully mixed with the soil, plough 10 cm with the soil, fine crush the soil, and build shade measures on the seedling bed after soil preparation and fertilization. it is easy to prevent direct sunlight from affecting the germination of seeds after sowing, and then prepare fine soil and fine sand around to cover the seeds after sowing, so as to improve the heat preservation and moisture retention capacity of the soil.

Second, 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 during cleaning, knead the seed coat, and then dry the seeds in the sun. When the seeds are in a semi-dry and semi-wet state, wrap them in a wet cloth and bury them in a mud basin, then pour the mud basin thoroughly and put it at a temperature of about 19 degrees to accelerate germination. In the process of accelerating germination, the seeds should be turned twice regularly to ensure that the seeds germinate evenly, and to keep the soil moist, it will sprout in about a week.

Third, 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, pay attention to the sowing amount and density when sowing, and do not sow too densely. Before sowing, you should first irrigate enough water, when the water seeps into the seedbed, then sow properly, and cover the prepared fine soil and sand in time after sowing. Then cover a layer of plastic film to improve the ability of the soil, do a good job in management after sowing, strengthen weeding, and improve the germination rate of seeds.

IV. Management at seedling stage

In order to prevent weeds from grabbing the germination and nutrition of seeds after sowing, herbicides should be used to control weeds properly. if weeds are not killed by herbicides, they should be pulled out manually in time, the seedlings should be opened after breaking the soil and watered in time, and the soil should be kept dry and wet in the future. if the air humidity is high and the ventilation is insufficient, we should pay attention to watering water to prevent celery diseases and insect pests from being caused, and when the seedlings are weak and lack of nutrition. To topdressing fertilizer in time, urea can be properly sprayed to the leaves, and seedlings should be sprayed at least twice in the seedling stage, first after the seedlings break the soil, and then again when the seedlings grow to 2 true leaves, and the seedlings should be strong and weak.

The above is the introduction of the technology of accelerating sprouting and raising seedlings of celery by the soil flow net. After the seedlings are unearthed, the management of the seedlings should be strengthened. Generally, they can be planted when the seedlings 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 when transplanting, affecting the normal growth of celery.
