What are the seed selection and seedling raising methods for carrots?
Speaking of carrots, I believe everyone is very familiar with them. They are cheap and affordable, can be prepared in many ways, and taste good. They can be said to be one of the most common edible vegetables grown in ordinary households. In addition, carrots are relatively simple to plant and manage, so they have also attracted many vegetable farmers and home gardeners. For these two groups of people, I believe they are very concerned about seed selection and seedling raising. Let's take a look below!
How are carrots selected for seed?
When selecting seeds, special attention should be paid to choosing seeds that are plump, fully developed, and have a high germination rate, and as far as possible use dehaired smooth seeds. Conduct germination rate tests to determine the suitable sowing rate. In terms of varieties, choose carrot varieties that are suitable for the local climate, soil, and other conditions and that taste good and have high yields for planting. Representative varieties include Xianong Seven-Inch, Japanese hybrid carrot, Red Core No. 6, New Five-Inch carrot, and so on.
What are the seedling raising methods?
1. Seedling raising time
Carrots are generally sown and raised for seedlings from late August to mid-September. With proper management, they can be harvested in November to December. When sowing, first water with clean water or manure water, then sow and cover with soil. This makes emergence easier.
2. Seed treatment
Before sowing, the seeds can first be soaked in warm water at 37 degrees for 12 hours, which can promote carrot germination. When sowing, you can choose furrow sowing or broadcast sowing. After sowing, cover with 1 cm of soil, then gently pat the bed surface flat with a shovel, which is beneficial for carrot germination.
3. Thin seedlings in time
After carrots emerge, thin the seedlings in time (that is, even out the seedlings), which can avoid seedlings crowding each other or poor lighting, but be sure to grasp the principle of thinning early and final thinning late. Generally, thin the seedlings once when carrots grow 2-3 true leaves, and thin them a second time when they grow 5-6 true leaves. The final spacing of 3-5 cm is suitable for carrot growth.
4. Land preparation and sowing
Apply sufficient base fertilizer before plowing. Generally, apply 3000-4000 kg of decomposed organic fertilizer and about 75 kg of special fertilizer for carrots per 667 sq m. After plowing, harrow finely 2-3 times to make the soil fine and free of clods, then form the land into wide beds for drilling. Carrot spring sowing is generally in mid-February, and autumn sowing is in early to mid-July. Place the treated seeds in shallow furrows and sow them along the furrows, cover with soil and press down, and immediately water thoroughly after sowing. Spray 800 times diluted Xin Gao Zhi Mo solution to preserve heat and moisture.
5. Seedling stage management
Autumn-sown carrots are very prone to seedling burn caused by dry and hot soil, causing the young stems of the seedlings to become wasp-waisted and die. Spray Di Guo Zhuang Di Ling in time, which can effectively improve the swelling vitality of the underground fruit and achieve the goals of robust fruit shape, high quality, and high yield. In addition, pay special attention to keeping the soil moist to ensure a full stand of seedlings.
Overall, carrot planting and management are relatively simple, and many households even have skilled growing experience. But if you want to grow carrots well, seedling raising is key, especially some small details in seedling stage management. This is the key to obtaining quality and yield.
