What are the key points of radish cultivation techniques? Explained clearly in one article

As the saying goes: winter radish, summer ginger. As a cheap and nutritious food therapy ingredient, radish cultivation can be said to be spread all over the world. Below is an introduction to the key points of radish cultivation techniques, so that everyone can easily grow large radishes.

Introduction to the key points of radish cultivation techniques

1. Timing

Radishes can basically be planted in all four seasons. Spring radishes are generally sown from February to April, summer radishes are sown from May to June, and autumn radishes and winter radishes are sown from July to August and in early to mid-September respectively. In addition, different sowing times mean different harvest times. After sowing, spring-sown spring radishes are generally harvested 50-60 days later; summer radishes grow quickly and are harvested 45-60 days after sowing; autumn and winter radishes are harvested 70-100 days after sowing. If the variety has fleshy roots mostly exposed above the ground, it should be harvested in time before Frost's Descent.

2. Sowing

There are three sowing methods for radishes: dibbling, drilling, and broadcasting. Before sowing, deep plowing is needed, with thorough freezing and sunning of the soil, then breaking up clods and raking level, and applying sufficient base fertilizer. Then sow the selected radish seeds suitable for local planting by dibbling, drilling, or broadcasting, with the specific row and plant spacing determined according to the variety and plot conditions. After sowing, cover with about 2 cm of soil. Watering is best done before sowing.

3. Thinning

Radish seedlings grow rapidly after emergence, so thinning should be done in time. In production, thinning is generally done 2-3 times. The first thinning is done when the first true leaf unfolds, and the second thinning when there are 2-3 true leaves.

4. Water and fertilizer

Radishes have different requirements for water and fertilizer at different growth stages. During the germination stage, there must be sufficient moisture. From the seedling stage until a period before “breaking belly,” water less to promote seedling establishment; during the vigorous leaf growth stage, water moderately; during the vigorous fleshy root growth stage, supply water fully and evenly. As for watering time, in early spring when temperatures are low it is best to water in the morning, while in dog days it is best to water in the evening to lower the soil temperature. If sufficient base fertilizer was applied for radishes, topdressing can be done after the seedlings produce 2 true leaves and after thinning and intertillage.

5. Intertillage and weeding

After radish sowing and seedling emergence, if rain or watering causes soil crusting, intertillage and weeding should be carried out in time.

During the growth period, radishes are susceptible to attacks from diseases and pests such as black rot, viral disease, aphids, cabbage caterpillars, and cabbage webworms. In addition to spraying pesticides for prevention, farmers should also promptly remove diseased and rotten leaves to avoid the spread of disease.
