What are the key points of timely sowing and seedling fixing of carrots? What should I pay attention to during this period?

Now the income from growing carrots is not higher than before. In order to increase income, it is necessary to expand the scale and plant large-scale saplings to reduce rising costs and income. The management of carrot seedlings is very important in large-scale planting. As long as we can gain a firm foothold in seedling raising, we can reduce the pressure of later planting. At the same time, we should pay attention to many points in stunt management. The period when carrots germinate and grow five leaves is called bud stage. During this period, the photosynthesis ability of carrot seedlings is weak, the root system is not fully restored, the absorption ability is not strong, and the growth rate is slow. At this stage, the resistance to seedlings is low and it is easily affected by weeds. If a leaf is planted for 5 days, if the management is not standardized, it will cause the loss of seedlings and the later edible effect will also be affected.

In order to ensure the healthy development of carrot seedlings, we should choose fields with sufficient nutrients for planting. The field should have a certain amount of fertilizer, be moist enough and have good drainage measures. Only in this way can the seedlings be raised normally. In order to increase the planting amount of carrots, it is necessary to ensure that the number of seedlings after seedling raising is sufficient, which is also the basis for ensuring yield. Therefore, after the seedlings are planted, the seedlings should be investigated in time. Because carrot seedlings are easy to die, the emergence rate is relatively low, sometimes less than 50%. Therefore, it is necessary to replenish saplings and improved varieties in time to ensure the perfection of seedlings. It takes 5 degrees for carrot seeds to germinate, the suitable temperature for germination is 22 degrees, the suitable temperature for growth is about 20 degrees during the day, and the temperature at night is about 15 degrees. When the temperature is below 3 degrees, the growth stops, the quality is not good, and the yield is low.

Carrots can only extract tundra fruits under the condition of light, which requires moderate light, sufficient light and good leaf growth. Insufficient light will thin the petiole. Carrots have developed roots, small leaf area and are relatively drought-tolerant. Therefore, carrots do not require high water content at seedling stage. At the middle stage of carrot, the soil moisture content is about 70%. When water is scarce for a long time, carrots are small and have many lateral roots, which are easy to produce rotten roots. Carrots like thick sandy soil, and the demand for potassium is relatively large, followed by nitrogen fertilizer, and the demand for phosphorus fertilizer is minimal. Carrots will grow longer when too much nitrogen fertilizer is used.

Carrots have higher requirements on soil, loose soil or prefer sandy soil. Otherwise, the skin will become rough, with prominent lateral roots and many forks. 1 mu of land can use 4 tons of fully decomposed 90 kg compound fertilizer, and the static depth can be combined with 30 cm. Carrot seeds have burrs, are not easy to absorb gasoline, germinate slowly and have irregular buds.
