How to grow carrot seedlings? Detailed explanation of the key points of seedling cultivation techniques

Carrot is a common vegetable in our daily lives, rich in various nutrients and deeply loved by consumers. In the process of growing carrots, the quality of seedling cultivation directly affects the yield of carrots. Now let's take a look at carrot seedling cultivation techniques together.

1. Careful seed selection

When selecting seeds, choose seeds that are plump and have a high germination rate, and try to use de-haired smooth seeds. Before sowing, conduct a germination rate test to determine the sowing rate. After selecting the seeds, rub off the prickly hairs on the seeds clean, soak the seeds in warm water at about 40°C for 2 hours, then soak them in potassium permanganate solution for half an hour, remove them and place them in a greenhouse at 20-25°C, maintain appropriate humidity, and turn them once every few hours. When some seeds show their radicles, they are ready for sowing.

2. Fine land preparation

For carrots, choose sandy loam soil rich in organic matter, with deep soil layers, loose texture and good drainage. The soil plowing depth is generally 25-30 cm. Before cultivation, apply sufficient base fertilizer, applying 3000-4000 kg of decomposed organic fertilizer per mu. After application, plow and harrow finely 2-3 times to make the soil fine and crumbly, then form wide beds.

3. Sowing

Carrots are generally sown in spring in mid-February, while autumn sowing is in early to mid-July. When sowing, first sow the treated seeds along the opened shallow furrows. The soil covering should not be too thick, generally not exceeding 1 cm. After compacting, water thoroughly, then spray New High Lipid Membrane to preserve heat and moisture. Before emergence, keep the soil moist but not dry to ensure emergence. After spring sowing, spray New High Lipid Membrane and cover with plastic film, while for autumn sowing, straw can be spread over the bed surface to preserve moisture and prevent rain, and also to prevent soil compaction.

4. Seedling stage management

After the seedlings emerge is a critical period for seedling stage management. Especially for autumn-sown carrots, soil overheating is very likely to cause seedling burn, causing the young stems of seedlings to die. Timely spray Diguo Zhuangdiling to thicken the nutrient transport vessels, accelerate the expansion of underground roots, and increase yield and quality. In addition, pay attention to controlling underground pests and weeds. You can apply 0.5 kg of phoxim per mu, mix it with soil, harrow once finely, then open furrows for sowing; for weed control, spray New High Lipid Membrane after sowing, which can achieve excellent weed control effects.
