Planting techniques of big carrot

Big carrot is a variety of radish, which is a kind of cruciferous vegetable. It has various effects such as clearing heat and removing blood stasis, nourishing heart and clearing blood, strengthening stomach and relieving cough, etc., which is welcomed by many people and has a great market demand. Therefore, now the planting area of carrots is relatively large. So how do you want to grow big red radish? Today, the editor has brought you the planting technology of big carrots. Let's take a look!

1. Land selection and preparation

Before planting big red radish, we first need to choose a suitable planting plot. Planting plots should ensure good permeability, high terrain, dry, and there are plenty of pollution-free water sources nearby. The soil is mainly sandy soil, and the permeability of clayey soil is too poor, which will affect the growth of big carrot. The previous crops planted in the soil should not be cruciferous crops and should be rotated for at least three years. Then carry on the soil preparation work, turn the soil deeply, break the soil, make the high border, keep the border surface smooth, and then apply about 2000kg farm manure per mu as base fertilizer.

2. Sowing seeds at the right time

The sowing time of carrots is usually from June to July every year, and the main sowing methods are hole sowing and sowing. Control the sowing rate and sprinkle the seeds evenly on the soil. If it is hole sowing, then put 6 seeds in each hole. After sowing, the soil should be covered properly, and the sowing depth should be controlled according to the degree of soil looseness. the soft soil can be sowed deeply, otherwise it should be shallow. If sowing in summer, then the soil should be covered with straw plastic film to improve the soil moisture conservation capacity. Promote seedling emergence, avoid soil hardening caused by Rain Water erosion, and reduce seedling emergence rate.

3. Seedling stage management

After the emergence of big carrots, we should appropriately increase the time between seedlings, delay the determination of seedlings, and ensure the strong seedling rate of big carrots. Adjust the interseedling time reasonably according to the sowing method, for example, if it is sowing, then the seedling should be interplanted for the first time when two true leaves appear in the seedling. The distance between strong seedlings was adjusted to about 8cm, and then the second seedling was carried out after about 11 days. If it is hole sowing, the seedlings can be interspersed about 7 days after emergence. After the first seedling intercropping, a weed control was carried out to promote the growth of the seedlings.

4. Water and fertilizer management

If sufficient base fertilizer is applied, the amount of topdressing can be reduced appropriately when planting. Generally, between the breaking of white carrots and the expansion period, apply a thin fertilizer and water, pay attention to control the concentration and fertilization position, to avoid root burning phenomenon. The demand for water in the growth of carrots is relatively large, so it is necessary to provide regular and quantitative supply. If the soil is short of water, it will have a great impact on the root growth of carrots. Easy to appear spicy, hollow and other bad phenomena. However, water should not be too much, which is easy to cause disease. We should water reasonably according to the growing period and water once a day after emergence to keep the soil moist.

The above is a brief introduction to the planting technology of big carrots. We should also pay attention to the drainage work, especially after the rain, to avoid affecting the growth of carrots. Finally, do a good job in pest control to ensure the normal growth of red radish. That's all for today's introduction. This article is for reference only. I hope it can help you all.
