Detailed Explanation of Key Points of Radish Field Management Techniques

There are quite a lot of radish varieties in China now, for example, grey radish, white radish, green-skinned radish, sweet radish, etc. Dishes made from radish are also quite popular, and most importantly, radish has relatively high efficacy and benefits. Moreover, the annual yield of radish is now quite considerable, which is inseparable from radish field management techniques. So today, the editor brings you radish field management techniques, hoping to be of some help to everyone.

1. Checking seedlings and thinning seedlings

Since radish is usually sown in rows when sowing, the amount of seeds used cannot be accurately controlled when scattering the seeds, so after emergence, the radish seedlings in many places grow relatively densely. Therefore, we need to first observe the seedling emergence in the field, and then carry out reasonable thinning. Usually, thinning is carried out with a plant spacing of about 30 cm, and only three to four of the best-growing seedlings need to be kept per plant.

2. Water management

The growth of radish requires sufficient water. After sowing, water once. Next, after the seedlings emerge, water management needs to be strengthened. Usually, water once about every three days. If the weather is hotter in summer, water every day. Finally, when the radish is expanding, reasonable watering is also needed. If the water in the field is insufficient, hollowing will occur, but if there is too much water, cracking and even rotting will also occur.

3. Fertilization management

One relatively important part of radish field management is fertilization management. In the early stage of radish growth, we usually focus on nitrogen fertilizer, or manure and urine water can also be used. When the radish tuber begins to grow, it is best to focus on potassium fertilizer and phosphorus fertilizer, as this can promote the growth of the radish tuber. During the radish growth period, according to normal topdressing, generally two to three times is appropriate. Finally, when fertilizing, do not sprinkle fertilizer on the leaves. Chemical fertilizer causes relatively great damage to the leaves, and at the same time it must not be too close to the radish roots.

4. Weeding and hilling

During the radish growth period, we need to carry out reasonable weeding. In the early and middle stages of radish growth, we usually use the method of intertillage weeding, which can loosen the soil and let it breathe. In the later stage, we usually use manual pulling of weeds for weeding, because if intertillage weeding is used in the later stage, it will cause damage to the radish.

5. Pest and disease control

Pest and disease control during the radish growth period is also an important task in field management. During this period, its main insect pests are aphids and cabbage worms, and we can directly use pirimicarb for control. Next, the most important disease is black rot. First, we can prevent and control it by enhancing soil permeability and water management, and then in the early stage of disease onset, we can use streptomycin for root irrigation treatment.
