How to grow radishes to get high yields?

Radish is an annual or biennial herb belonging to the genus Raphanus in the family Cruciferae. It is cultivated everywhere, especially in areas with suitable climate, and can be grown almost all year round. In most areas, radish is mainly planted in autumn. The growing period of radish is about 70 to 120 days, making it one of the most widely grown root vegetables. Radishes are divided into winter radishes, spring radishes and summer and autumn radishes, and are one of the main vegetables in autumn and winter. Radish not only has high yield, but is also durable in storage and transportation, so growing radish has high economic benefits. So how can we grow radishes to achieve high yields?

1. Choose a suitable planting site and prepare the land

Radishes can adapt to a variety of soils, but in order to achieve high yields, it is best to choose a plot with deep, loose, fertile soil that retains water and fertilizer. Radishes have shallow roots and require deep plowing and fine raking, especially large radishes, which require deep plowing of more than 30 cm. The base fertilizer should be sufficient, usually 2,000 to 3,000 kilograms of decomposed farmyard manure and 100 kilograms of wood ash or 40 kilograms of potassium sulfate are applied per mu. The cultivation method adopted is deep trench and narrow bed, with bed height of 15 to 20 cm, width of 100 to 130 cm, and 3 to 4 rows planted in each bed.

2. Sow seeds at the right time

Winter radishes are best sown from August to September, spring radishes from early October to mid-November, and summer and autumn radishes from May to July.

3. Timely thinning and final seedling determination

Radish seedlings grow quickly and need to be thinned out in time to avoid crowding and leggy growth. Generally, thinning is done 2 to 3 times, the first time when the first true leaf unfolds, followed by thinning again depending on the growth conditions, and finalizing when the seedlings burst.

4. Reasonable irrigation

Radishes require a lot of water, especially during the germination period, the soil needs to be kept moist. Insufficient soil moisture during the period of fleshy root formation will reduce yield and affect quality. At the same time, excessive soil moisture can also cause fleshy roots to crack.

5. Apply fertilizer in stages

Base fertilizer is the main fertilizer, supplemented by top dressing. Large radishes have a long growing period and need to be topdressed with decomposed human manure and urine after thinning, and with more concentrated manure water and compound fertilizer when they burst. Strictly control the amount of nitrogen fertilizer used, and the amount of pure nitrogen applied per mu shall not exceed 8 kg.

6. Cultivation, weeding and soil cultivation

Keep the soil loose, cultivate and weed in time to prevent weed damage. In the middle and late stages of growth, old yellow leaves should be removed to facilitate ventilation.

7. Preventing Radish from Turnips

Blackheart can be caused by disease, soil compaction, or the application of unrotted fertilizer . Prevention can be achieved through strengthening field management, timely tillage, application of well-rotted farmyard manure and disease control.

8. Harvest at the right time

Harvesting too early will result in low yields, while harvesting too late may result in frost damage or hollowness. Spring radishes are generally harvested from March to May, and winter radishes from late October to February of the following year. Stop applying nitrogen fertilizer 20 days before harvest.

Through the above measures, the yield and quality of radish can be effectively improved. If you have any other questions during the process of growing radishes, you can also leave a message.
