1、 Planting time

It has many varieties. The planting time of different varieties will naturally vary, but the approximate time is the same. It is mostly concentrated around the first ten days of September, which is probably the Bailu solar term. At this time, the temperature and climate are more conducive to growth and management

2、 Germination and sowing

Its sowing method is very simple, just direct sowing. However, it is recommended to accelerate germination before sowing, soak the seeds in clean water for 12 hours, dry them and put them in an environment of about 23 degrees. They can be sown when the buds are exposed, which will improve the probability of budding

3、 Timely setting

The value can be set when the seedlings grow four real leaves. Pay attention to eliminate the short seedlings, long seedlings and sick seedlings, and only select the strong seedlings, so that they can grow better in the later stage. The fixed value is mostly carried out at the end of October, and the plant row spacing is about 20 × 15 cm

4、 Field management

After the fixed value is good, we should pay attention to the management of fertilizer and water and the prevention and control of diseases and pests. The top dressing is mainly urea and nitrogen phosphorus potassium compound fertilizer. Topdressing treatment should be carried out during the peak growth season and bulb expansion, which can be carried out in combination with watering. The main diseases to be controlled are rust, purple spot and downy mildew, and the pests are mainly onion thistle. At ordinary times, we should have more ventilation and timely drainage. If you find diseases and pests, you should apply the right medicine to the case
