To ensure a successful carrot cultivation process, it's essential to follow a well-structured approach from preparation to harvesting. Here’s a detailed and improved version of the original content:

**1. Preparing the Field Before Planting**
First, choose a suitable soil type. The ideal soil should be rich in organic matter, well-draining, and loamy or sandy loam. Previous crops such as wheat, corn, or beans are good predecessors, with beans being the most favorable. After the previous crop is harvested, plow the land to a depth of 25–30 cm. Before tilling, apply 2,500–3,000 kg of well-rotted organic manure per mu to enrich the soil. Then, level the field by watering it, breaking up clods, and digging to a depth of 15 cm to meet the six criteria: “Qing (loose), Ping (flat), Song (soft), Broken (crumbly), Net (well-drained), Shu (moist).â€
For variety selection, consider popular processed carrot types like Japan’s “New Kuroda Ginseng†and the U.S. variety “Red Heart Golden Bamboo Shoots.†These varieties have growth periods of about 120 and 135 days respectively, making them suitable for summer planting.
Before sowing, soak seeds in warm water for 3 hours, then place them in a clean, moist cloth to germinate at 20–25°C. Keep the seeds moist by misting regularly. Once most of the seeds show white sprouts, they are ready to be sown.

**2. Sowing the Seeds**
Determine the best sowing time based on average temperatures, which should be above 13°C. In general, this occurs around mid-May, though specific timing may vary depending on local climate and variety. For instance, “American Golden Bamboo Shoots†should be sown slightly earlier than “New Kuroda Ginseng.†Sowing too early increases the risk of bolting, while sowing too late can reduce yield and quality.
Use mechanical sowing to ensure even distribution. Mix 450–500 grams of seeds with 5 times the amount of fine sand or dry sawdust, and sow them at a depth of 1.5 cm with a spacing of 25–30 cm between rows. After sowing, lightly press the soil and cover with a thin layer of fine soil. To protect the seeds, you can cover them with straw or intercrop with cabbage or oilseed rape to provide shade during the early growth stages.

**3. Seedling Management**
During the seedling stage, if high temperatures or drought occur, irrigate 1–2 times to aid emergence. About 15 days after sowing, the first true leaves appear. At this point, thin out the seedlings, removing weak or small ones, leaving only the strongest. Maintain a spacing of 7 cm between plants, aiming for 30,000–33,000 seedlings per mu. Perform the first cultivation to loosen the soil. As the plants develop 4–5 leaves, perform the second cultivation and manually remove weeds. Avoid using chemical herbicides to maintain product quality.

**4. Watering During Root Development**
When the roots begin to thicken, this is the peak period for water demand. Ensure consistent and moderate irrigation—avoid flooding or letting the soil dry completely, as this can cause root cracking. Aim for 3–4 irrigation sessions throughout the growing season.
---
**5. Fertilization**
If the soil lacks fertility, apply quick-release organic fertilizer during root development. Use 1,000 kg of composted manure per mu, mixed with water and applied directly to the roots. This prevents root burn due to concentration. Repeat this process every 15–20 days to support healthy growth.

**6. Pest and Disease Control**
Prioritize biological and physical control methods over chemical pesticides, especially systemic ones. Common pests include ground beetles and seed flies. Ground beetles feed on young plants at night, so manual collection or bait traps made with trichlorfon-treated bran or oil residue can be effective. For seed flies, use a sugar-vinegar-water mixture to trap adults during sunny midday hours.
Diseases like powdery mildew and bacterial soft rot can also occur. Apply agricultural anti-irritant diluted 150–200 times at the first sign of disease. For bacterial soft rot, remove infected plants immediately, disinfect the area with lime, and spray 50% DT WP diluted 500 times. Apply this treatment 2–3 times with a 7–10 day interval for prevention.

**7. Harvesting**
Harvest when the outer leaves turn yellow and the inner leaves remain green, indicating physiological maturity. You can harvest manually or mechanically, depending on the scale of your operation.
