Management techniques of celery seedling stage

Celery is a plant of Umbelliferae, there are many varieties in our country, and it has been planted for a long time in our country. The nutritional value of celery is very high and is rich in nutritional elements. So now there are still a lot of people growing celery, so when we plant celery, how to manage it at the seedling stage? The following editor brings you the management technology of celery seedling stage, let's have a look!

1. Management at emergence stage

After accelerating germination, celery seeds absorb enough water and ensure the right temperature, then the emergence speed of celery seeds is relatively fast. Under normal circumstances, it takes about a week for celery to reach full seeding after sowing. Although the time is not very long, it is still necessary to do a good job in management. Need to focus on adjusting the temperature and moisture and other two aspects. In the emergence stage, we should pay attention to check the germination of seeds, and pay attention to the dry humidity and light intensity of the soil. However, the sunshade net is used to cover the whole seedling stage, and when a pair of cotyledons are unearthed from celery seedlings, the sunshade net can be properly removed.

2. Management of seedling growth period.

Celery seedlings grow from two leaves to about six leaves, which is the growth period of the seedlings. The management work in this period directly determines whether the strong seedlings are cultivated successfully. First of all, we should pay attention to control the coverage of the sunshade net, in sunny days, generally from 8 o'clock to 16:00 to cover the sunshade net time, the rest of the time can not be covered. If it is cloudy or rainy, there is no need to cover the net. Then we should do a good job of water and fertilizer work, if it is a rainy day, then we should give priority to one net and one film, so as to avoid the soil from being affected by rain and excessive humidity. However, when the temperature is high in summer, if the soil is dry, spray water in time.

When the seedlings grow to about 4 leaves, foliar fertilizer should be sprayed properly. Foliar fertilizer can be used mainly by plant power and sprayed twice to enhance the growth ability of seedlings. Then we should pay attention to the temperature control and adjust the temperature by controlling the cover of the sunshade net. The temperature should generally be controlled at about 20 degrees, with a maximum of no more than 25 degrees. Finally, we should also pay attention to the prevention and control of diseases, the use of chlorothalonil, Jinggangmycin and other agents for prevention. Spray the fungicide once in about 7 days and last for about a month. Among them, the common diseases and pests of celery in seedling stage are blight, quenching disease, aphids and so on.

3. Integrated management

In the growth process of celery seedlings, we should pay attention to observe the growth of celery seedlings. In particular, celery should be checked in time, if there is a lack of seedlings or weak seedlings, then it is necessary to replant healthy seedlings with the same growth in time. Then, when the seedlings were customized, Jintailong was mixed with water, the sprinkler was removed and then sprayed on the roots of celery seedlings to promote the root growth of the seedlings and speed up the slow-down speed of the seedlings.

The above is a brief introduction of celery seedling management technology. That's all for today's introduction. This article is for reference only. I hope it can help you all.
