Planting time of radish seeds
Radish seeds can be planted all year round, spring radish is suitable for planting in February-April, summer radish is suitable for planting in May-June, autumn radish is suitable for planting in July-August, and winter radish is suitable for planting in the first half of September.
Method for plan radish seeds
1, screening soil
It is necessary to choose suitable soil before planting radish seeds. Radish seeds like fertile soil with loose and porous structure and good drainage and ventilation. The most important thing is that cruciferous plants cannot be planted in the previous crop, otherwise it will be harmful to the growth and development of radish.
Step 2 sow seeds
The ability of independent germination of radish seeds is weak, and the germination rate is not high. In order to ensure adequate reproduction scale and survival rate of radish, it is generally necessary to drill many crypts at regular intervals in the selected soil, and then fill each crypt with four seeds, so as to ensure the survival rate.
Step 3 control the temperature
Radish has certain cold tolerance and low temperature tolerance, but its tolerance to high temperature is relatively poor. Therefore, after sowing, it is necessary to ensure that the ambient temperature is not higher than 22 degrees Celsius at the highest and not lower than 3 degrees Celsius at the lowest, so that radish can grow vigorously and rapidly.
Matters needing attention in radish seed planting
After sowing radish, management needs to be strengthened. Generally, seedlings will grow in about 7 days. Because of the differences in nutrition, moisture and seed quality, the seedlings themselves will have different growth trends. In the process of their growth, it is necessary to carry out thinning work to remove too weak, thin and lodging seedlings, and regularly check the fields to remove weeds.
