How to grow carrot seedlings? Latest technical method tutorial
Carrot is a common vegetable in our daily lives, rich in various nutrients and deeply loved by consumers, and in the process of growing carrots, the quality of seedling raising directly affects the yield of carrots. Let's take a look together at carrot seedling raising techniques.
1. Careful seed selection
When selecting seeds, choose seeds that are plump and have a high germination rate, and try to use dehaired smooth seeds. Before sowing, carry out a germination rate test to determine the sowing rate. After selecting the seeds, rub the spines off the seeds clean, soak the seeds in warm water at about 40 degrees 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 degrees, maintain appropriate humidity, and turn them once every few hours. When some seeds have their radicles exposed, they can be sown.
2. Fine land preparation
For seeding carrots, choose sandy loam soil rich in organic matter, with deep soil layers, loose texture and good drainage. The soil ploughing depth is generally 25-30 cm. Before cultivation, apply sufficient base fertilizer, applying 3000-4000 kg of decomposed organic fertilizer per mu. After applying, plough and harrow finely 2-3 times to make the soil fine and crumbly, then prepare the land into 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, and the covering soil should not be too thick, generally no more than 1 cm. After compacting, water thoroughly, then spray with Xinsuanzhi film to preserve heat and moisture. Before emergence, keep the soil moist but not dry to ensure emergence. After spring sowing and spraying with Xinsuanzhi film, cover with plastic film, while for autumn sowing, straw can be spread over the bed surface to preserve moisture, prevent rain, and also prevent soil compaction.
4. Seedling stage management
After the seedlings emerge is a key period for seedling stage management, especially for autumn-sown radishes, which are very prone to soil drying and heating that causes seedling burn, causing the tender stems of the seedlings to die. Spray with Diguo Zhuangdiling in time to make the nutrient transport vessels thicker, accelerate the expansion of underground fruit, 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 finely once, then open furrows and sow; for weeding, spray with Xinsuanzhi film after sowing, which can achieve an excellent weeding effect.
