Management techniques of Carrot Seedling stage

Carrots have many growth stages, among which the seedling stage is when the seedlings have about 6 true leaves. The growth ability of carrots in seedling stage is not strong, the growth rate is slow, and it takes a long time to grow a true leaf every other week. Young carrots are very fragile, so we must strengthen management. The following editor brings you the management technology of carrot seedling stage, let's have a look!

1. Check and replenish seedlings

In the seedling stage, we must do a good job of seedling inspection, and often observe the growth of seedlings to ensure the normal growth of all seedlings and improve their own yield. If weak or dead seedlings are found in the planting, they should be pulled out in time, and then the healthy seedlings with the same growth should be made up. If the number of weak carrot seedlings is more than half of the dead seedlings, then it means that there is a disease and the seeds should be destroyed in time.

2. The seedlings are fixed

In the young seedling stage of carrot, it is not only necessary to check and replenish the seedlings, but also to determine the seedlings in time to prevent the seedlings from competing for nutrition and affecting the growth of the seedlings. We should control the planting density according to the varieties of carrots and soil conditions to fix the seedlings, and then pull out the poor seedlings such as weak growth, diseases and insect pests in time. In the 5 leaves when combined with ploughing weeding work to fix seedlings, should be carried out in batches, pay attention to planting density, not too thin and too dense.

3. Rational watering

When sowing in summer, because the temperature is too high, the growth rate of water is fast, and the roots of carrots are strong, so the soil is easy to lack water at the seedling stage, resulting in the drying and death of the seedlings. However, water should not be too much, because if the soil is too wet, it is easy to cause carrots to rot and cause all kinds of diseases and insect pests, so we should water reasonably. In the hot season, we should not water at noon to prevent the water temperature from rising and scalding the seedlings. And drainage should be done in time when it is rainy.

4. Weeding in time

The growth rate of carrots in seedling stage is slow, but the growth rate of weeds is fast, so timely weeding is the key to ensure the healthy growth of carrots. When the seedlings should be carried out together, chemical weeding methods can be used, but we should pay attention to the dosage, not too much, to prevent the inhibition of carrot seedlings. When choosing herbicides, be sure to choose those that will not affect crops and avoid reducing planting benefits.

5. Pest control

As I just said, carrot seedlings are relatively fragile, so the harm of diseases and insect pests is also relatively large. Therefore, we must also do a good job in the prevention and management of diseases and insect pests, in the seedling stage, the common diseases and insect pests are powdery mildew, root-knot nematode and so on. It should be checked frequently, and corresponding measures should be taken in time when abnormal conditions are found. In addition, it is necessary to do a good job in prevention, regular disinfection, strengthen the management of water and fertilizer, do a good job in weeding and weeding, and reduce the incidence of diseases and insect pests.

The above is a brief introduction of carrot seedling management technology, carrot seedling management is directly related to the growth and yield of carrots, so we must pay more attention. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
