Carrot planting fertilization and watering methods (when is the best time to water carrots after planting)

Carrots can be considered an indispensable ingredient in our daily diet. How can we grow high-quality and high-yield carrots?

The answer is to master scientific planting and management: not only should water-soluble fertilizers be applied on time, but also seed selection, land leveling and other work should be done to ensure the healthy growth of carrots.

Preparations for planting carrots

Before sowing carrots, three tasks must be completed: land preparation, base fertilizer application and sowing. Among them, land preparation and base fertilizer application can be carried out at the same time.

Generally, land preparation work can be carried out after the upper crop is harvested. Deep plowing of 20-30 cm is carried out, and then sufficient organic fertilizer and microbial agents are applied per acre.

When preparing the land, you should also pay attention to clearing away debris in the field to prevent pathogens in the debris from spreading diseases.

Carrots are generally sown from July to August, and it is best to sow them before the beginning of autumn. When sowing, dig double rows of furrows with a row spacing of 10 cm on the top of the ridge. The furrow depth is about 1 cm. Water first, then sow the seeds and cover them with soil. You can use wheat straw, hay, etc.

Management of carrots after sowing

After the carrots are planted, it is important to prepare the soil and apply fertilizers, which will have a great impact on the later growth of the carrots. Generally, when selecting a site, it is more appropriate to choose deep, fertile, humus-rich and well-drained loam or sandy loam.

The fertilization of carrots should be adjusted according to their growth stage. For example, balanced water-soluble fertilizers are mainly used in the seedling stage, and in the later stage, the content of phosphorus and potassium elements should be gradually increased.

In addition, carrots are root crops, so it is necessary to add microbial agents during daily fertilization, which can promote the development of the root system and increase the yield of carrots.

1. Watering and irrigation management

Carrots are relatively drought-resistant and generally do not require watering because they have a small leaf area, low evaporation, a well-developed root system, and strong absorption capacity.

Although carrot plants are highly drought-resistant, they also need to be watered in a timely manner. Only through reasonable irrigation can they maintain normal growth. If there is a lack of water, the growth of carrot seedlings will easily be hindered.

Therefore, reasonable watering is very important. After sowing, we must water the seedlings evenly to keep the ridge surface moist, avoid alternating between dry and wet, and ensure uniform emergence of seedlings.

After the seedlings have grown to full height, if they are not dry, try to water them as little as possible, mainly to promote downward growth of the roots.

During the period of fleshy root expansion, the plant's demand for water is the greatest. Therefore, we must provide sufficient water supply. If we do not water enough, the carrots will become small and of poor quality.

In addition, we must strictly prohibit water accumulation in the fields, and drain water in time after heavy rains. Otherwise, root rot and fleshy root bifurcation are likely to occur, affecting the quality and yield of carrots.

2. Fertilization management

Before tilling the soil, we should apply enough base fertilizer, 2500-3000 kg of farmyard manure per acre of land, and then deep plow the soil after application.

During the growth period of carrots, we need to apply fertilizer twice. In order to avoid burning the roots, we can combine it with watering, using water to carry fertilizer, and it is better to apply thin fertilizer in the seedling stage and thick fertilizer in the later stage.

The first top dressing is usually carried out 20-25 days after seedlings appear and when there are 3-4 true leaves. 2-3 kg of ammonium sulfate, 3-5 kg ​​of superphosphate and 1-2 kg of potassium chloride are applied per acre of land.

After 25-30 days, apply the second fertilizer , 7-10 kg of ammonium sulfate, 3-5 kg ​​of superphosphate, and 3-4 kg of potassium chloride per acre of land.

Pay attention to the growth regulation of carrots

The growth of carrots requires certain conditions, such as temperature requirements: the most suitable temperature for carrot growth is 23-25 ​​degrees during the day and 12-15 degrees at night. The large temperature difference determines the superior quality of carrots and increases the sugar content.

In addition, water is also a component that carrots require in large quantities. Only sufficient water can allow the carrot roots to expand and develop, increasing the final quality and yield.

Generally, the soil moisture content is required to be above 20%, and it is best when it can be kneaded into a ball and falls apart when touched.
