How to grow white radish? All the key methods are here

White radish is a plant of the genus Raphanus in the Brassicaceae family, and is a common root vegetable in daily life. White radish has fine, dense flesh, is sweet and juicy, and is rich in nutrients, with high edible value. It is highly favored by the market and has good cultivation value, attracting many farmers to grow it. So, how do you grow white radish? The pollution-free, high-yield cultivation techniques for white radish are introduced below.

1. Soil selection

It is advisable to choose sandy loam, loam and light clay soil that is loose and fertile and rich in organic matter.

2. Fine land preparation

After the previous crop is harvested, remove residual leaves and weeds, pick out stones and gravel, and deep-plow to break up the clods.

1. Pure cropping:Carry out deep plowing to a depth of more than 30 cm, and sun-bake the soil for 5-7 days. Apply 1500-2000 kg of decomposed farmyard manure, 30 kg of ordinary calcium superphosphate, 10-15 kg of potassium sulfate, and 0.5-1 kg of borax per mu.

2. Intercropping:After more than half of the flue-cured tobacco plants have been harvested and cured, plow and merge two tobacco ridges into one, with a ridge width of about 2 m and a plant-to-row spacing of 35-40 cm. Apply 5-8 kg of compound fertilizer per mu as seed fertilizer, scattering it into the planting holes.

3. Sowing

1. Seed treatment:Before sowing, carefully select the seeds, remove weeds, and place them in the sun to dry for 2-3 hours.

2. Sowing techniques:Before sowing, water thoroughly to ensure adequate bottom water. Sow 3-4 seeds per hole, and sow the seeds at a moderate density, using 0.3-0.4 kg of seed per mu. After sowing, mix 500-1000 kg of fine manure soil per mu with 15-20 kg of ordinary calcium superphosphate, 15-20 kg of potassium sulfate, 0.5-1 kg of borax, and 3 kg of sulfur-phosphorus granules, mix well, and cover the holes.

4. Thinning and final singling

Master the principle of "thin early, single late." The first thinning is done when there are 2-3 leaves, removing small, diseased and weak seedlings, leaving 2-3 vigorous seedlings per hole. When there are 5-6 leaves, carry out final singling, leaving only one plant per hole. When singling, according to the growth of the whole field, pull out small, weak seedlings and larger seedlings, so that the plants grow uniformly and consistently.

5. Cultivation, weeding and earthing up

White radish needs 2-3 cultivations throughout the production period, first deep and then shallow, first near and then far, to avoid damaging the roots. Stop cultivation after the rows close. During the last cultivation, place the soil from the furrows onto the ridge surface to prevent the plants from falling over.

6. Watering

This should be determined according to the crop's growth stage, rainfall, temperature, soil texture, groundwater level, and air and soil moisture conditions. Generally, water less during the seedling stage to encourage roots to grow deeper; during the peak leaf growth stage, more water is needed, so irrigate appropriately, but not too much, to avoid excessive vegetative growth; during the rapid thickening stage of the fleshy root, irrigate evenly to promote the growth of the fleshy root and make it plumper and more tender; stop irrigation half a month before harvest to improve quality and storability.

7. Scientific fertilization

Determine the timing of topdressing according to soil fertility and growth conditions, generally carried out in two applications during the seedling stage, leaf growth stage and peak fleshy root growth stage. During the seedling stage and peak leaf growth stage, mainly apply nitrogen fertilizer, applying 10 kg of urea and 15 kg of ternary compound fertilizer; during the peak fleshy root growth stage, apply more phosphorus and potassium fertilizer, applying 15 kg of ordinary calcium superphosphate, 10 kg of urea, and 25 kg of nitrogen-phosphorus-potassium compound fertilizer, while adding 0.5-1 kg of borax. Quick-acting nitrogen fertilizer should not be used within 20 days before harvest.

8. Integrated pest and disease control

Follow the plant protection policy of "prevention first, integrated control," giving priority to agricultural control, physical control and biological control, combined with scientific and rational use of chemical control. When using chemical control, scientifically use new pesticides that are efficient, low-toxicity and low-residue, so that chemical control of pests and diseases is accurate, early and at a small scale, and reasonably mix, rotate and alternate medications.

9. Timely harvest

When the fleshy root of the white radish has fully expanded, the leaf color turns dark and begins to yellow, and coarse lines appear on the root head, harvest in time, generally about 70 days after sowing. According to market demand, process it into shredded or strip-cut white radish, dry it in the sun, and store it for sale.

[Editor's concluding remarks]White radish is a common vegetable that can be eaten raw or cooked, and also has certain medicinal value, with very high benefits. The above has introduced the pollution-free, high-yield cultivation techniques for white radish, and I hope it will be helpful to everyone!
