Introduction of cultivation techniques of radish

1. time

Radish can be planted all the year round. Spring radish is generally sown from February to April, summer radish is sown from May to June, autumn radish and winter radish are sown from July to August and mid-early September respectively. In addition, the sowing time is different, the harvest time is also different. Spring radish is generally harvested 50-60 days after sowing; summer radish grows fast and 45-60 days after sowing; autumn and winter radish is harvested 70-100 days after sowing. If most of the fleshy roots are exposed on the ground, they should be harvested in time before Frosts Descent.

two。 Sowing seeds

There are three sowing methods of radish: on-demand, strip sowing and sowing. Before sowing, it is necessary to plough deeply, fully freeze and dry, break rake flat, and apply sufficient base fertilizer. Then the radish seeds selected for local planting are sown by on-demand, strip sowing or sowing, and the specific row-plant spacing is determined according to the variety and plot conditions. The soil cover is about 2 cm after sowing, and watering is best carried out before sowing.

3. Intermediate seedling

The seedlings of radish grow rapidly after being unearthed, and the seedlings should be planted in time, and the seedlings are generally produced for 2-3 times. The first seedling was carried out when the first true leaf was expanded, and the second seedling was carried out when there were 2-3 true leaves.

4. Water and fertilizer

Radish has different requirements for water and fertilizer at different growth stages. There should be sufficient water in the germination stage, less watering to facilitate squatting seedlings from the seedling stage to the period before "breaking the belly", proper watering in the peak period of leaf growth, and full and uniform water supply in the peak period of fleshy root growth. Watering time, low temperature in early spring should be watered in the morning, summer days had better be watered in the evening, in order to reduce the ground temperature. If the radish base fertilizer is fully applied, topdressing can be carried out after 2 true leaves are produced in the seedlings and ploughed among the seedlings.

5. Intermediate ploughing and weeding

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

During the growing period, radish is vulnerable to black rot, virus diseases, aphids, vegetable green insects, vegetable borer and other diseases and insect pests. Farmers should not only spray pesticides to prevent, but also remove diseased and rotten leaves in time to avoid the spread of diseases.
