Seedling raising techniques of Carrot

Carrot is a common vegetable in our life, rich in a variety of nutrients, loved by the majority of consumers, and in the process of carrot planting, its seedling quality directly affects the yield of carrots. Let's follow the editor to take a look at the breeding techniques of carrots.

1. Careful selection of species

When selecting seeds, the seeds with full grains and high germination rate should be selected, and the light seeds treated with depilation should be selected as far as possible, and the germination rate test should be done before sowing in order to determine the sowing rate. After seed selection, rub the prickles on the seeds clean, soak the seeds in warm water of about 40 degrees for 2 hours, soak them in potassium permanganate solution for half an hour, fish them out, place them in a greenhouse at 20-25 degrees, maintain appropriate humidity, and turn them every few hours. When part of the seed radicle is exposed, it can be sowed.

2. Fine land preparation

Seed carrots should choose sandy loam soil rich in organic matter, deep soil layer, loose soil and good drainage, and the soil ploughing depth is generally 25-30 cm. Apply sufficient basic fertilizer before tillage, apply 3000-4000 kg of rotten organic fertilizer per mu, and fine rake 2-3 times after ploughing to make the soil fine and form a wide border in soil preparation.

3. Sowing seeds

Carrots are generally sown in spring in mid-February and in autumn in early and mid-July. When sowing, the treated seeds are first sown along the open shallow ditch, and the soil cover should not be too thick, generally no more than 1 cm. Pour water thoroughly after suppression and spray new high-fat film to keep heat and preserve soil moisture. It is necessary to keep the soil wet but not dry before emergence to ensure seedling emergence. Spring sowing sprays new high-fat film to cover plastic film, while autumn sowing can cover straw on the border, preserve soil moisture and prevent rain, and prevent soil consolidation.

4. Seedling stage management

After the seedlings are unearthed, it is the key period of seedling management, especially the autumn radish is easy to burn seedlings caused by dry heat of the soil, resulting in the death of young stems of seedlings. It is necessary to spray Zhuangtieling in time to thicken the nutrition transport pipe and speed up the expansion of underground fruit. Yield and quality. In addition, we should also pay attention to the control of underground pests and weeding, 0.5 kg of phoxim can be applied per mu, mixed with soil, raked again and then sown; weeding can be sprayed with new high-fat film after sowing, which can have an excellent weeding effect.
