1, planting time
The planting time of water radish is generally from May to August. If it is planted in a greenhouse, it can be planted all year round.
2, accelerating germination and sowing
The method of accelerating germination of radish seeds is to soak the seeds in warm water at 30℃ for 3 ~ 4 hours, then drain the water, wrap them in wet gauze and put them by the fire to accelerate germination. You can also wrap a layer of plastic film on gauze and stick it on your body to accelerate germination, and then sow when the seeds are white.
3. Soil preparation and fertilization
Preparations before sowing, such as soil preparation, fertilization and watering, are carried out in the early winter of the year. When preparing soil, 2000 kilograms of decomposed and finely mixed Hefei should be applied per mu and evenly spread on the border. Before the soil freezes before the light snow festival in late June, water the border once in 165438+ 10.
4. Sowing method
When sowing, you can ditch and drill, water first, and then sow. Leveling after sowing, covering soil 1 ~ 1. Centimeter. Generally, 5 ~ 6 days after sowing, if no seedlings or broken ridges are found, replanting should be done in time to ensure the whole seedlings.
5, thinning seedlings
After sowing, it usually takes 15 ~ 20 days to emerge because of the low temperature and slow emergence in early spring. Sow the seedlings when they grow 2-3 true leaves. Because only one seedling is used, this time the thinning seedling is a fixed seedling.
6. Topdressing and watering
After the radish "burst", when the fleshy roots began to grow rapidly, watering was started to promote the expansion of the fleshy roots. After controlling seedlings 10 days, the growth of leaves was controlled and the fleshy roots entered a rapid expansion period. Water for the second time, and apply 25 kilograms of ammonium sulfate per mu. Water every 5 to 7 days until the harvest.
