How to choose carrots? What are the methods of raising seedlings?

Speaking of carrots, I believe everyone is very familiar with, cheap and cost-effective, diverse and delicious practices, can be said to be one of the most common edible vegetables in daily families. In addition, the cultivation and management of carrots is also relatively simple, so it also attracts many vegetable farmers and family vegetable friends. For these two types of people, I believe they are very concerned about seed selection and seedling raising. Let's take a look at it.

How to choose carrots?

In seed selection, special attention should be paid to the selection of full, fruiting and high germination rate seeds, and the light seeds treated with depilation should be selected as far as possible, and the germination rate test should be done to determine the appropriate sowing rate. In terms of varieties, carrots with good taste and high yield are selected for planting, which are suitable for local climate, soil and other conditions. the representative varieties are Shannong seven-inch, Japanese hybrid carrot, Hongxin 6, new five-inch carrot and so on.

What are the methods of raising seedlings?

1. Seedling raising time

Carrots are usually sown and raised from late August to mid-September. If properly managed, carrots can be harvested from November to December. When sowing, you should first pour clear water or dung water, and then sow and cover the soil, so that the seedling capacity is higher.

2. Seed treatment

Before sowing, soak the seeds in warm water at 37 degrees for 12 hours to promote carrot germination. When sowing, you can choose ditch sowing or sowing, cover 1 cm of soil after sowing, and gently pat the border surface with a spade, which is conducive to carrot germination.

3. Timely intercropping

After the emergence of carrots, it is necessary to interseedling (that is, uniform seedlings) in time to avoid mutual crowding or poor light, but we must grasp the principle of early seedlings and late seedlings. Generally, it is suitable for the growth of carrots when they grow 2-3 true leaves once, and between 5-6 true leaves for the second time, and the final interval is 3-5 cm.

4. Soil preparation and sowing

Apply sufficient basic fertilizer before ploughing, generally spread 3000-4000 kg of rotten organic fertilizer and 75 kg of carrot special fertilizer every 667m2, fine rake 2-3 times after ploughing, so that the soil is fine and unbumpy, and then the land is divided into wide beds for strip sowing. Carrots are generally sown in spring in mid-February and in autumn in the first and middle of July. The treated seeds are sown in shallow trenches and then pressed by covering soil. Immediately after sowing, carrots are watered thoroughly and sprayed with 800-fold liquid of new high-fat film to keep moisture.

5. Seedling stage management

Autumn sowing carrots are easy to burn seedlings caused by dry heat in the soil, which makes the tender stems of seedlings become bee waist and die. Spraying Diguo Zhuangtieling in time can effectively improve the swelling vitality of ground fruit and achieve the purpose of strong fruit type, high quality and high yield. In addition, special attention should be paid to keeping the soil moist to preserve the seedlings.

Generally speaking, the planting management of carrots is relatively simple, and even many families have skilled planting experience. But if you want to grow carrots well, raising seedlings is the key, especially some small details in seedling management, which is the key to obtaining quality and yield.
