What to Do If Spinach Has a Low Emergence Rate After Sowing
Because spinach seeds are covered with a layer of gelatinous material on their surface, conventional sowing not only results in slow and uneven emergence, but also poor sowing quality, which seriously affects the later growth of spinach. So what methods can make spinach seeds emerge quickly and evenly? Let's take a look.
1. Preparing the Solution
After years of practice, soaking seeds in hydrogen peroxide solution has proven successful and is currently being promoted and used at some vegetable production bases in various regions. To soak seeds in hydrogen peroxide solution, you first need to master the solution preparation. You can dilute hydrogen peroxide solution with water at a ratio of 1:4, and after thorough stirring, prepare a 20%-25% hydrogen peroxide solution.
2. Soaking Time
First, place the prepared hydrogen peroxide solution in a container, then pour the seeds into the container while stirring so that the seeds can absorb water evenly. The soaking time should be determined according to the temperature: when the temperature is below 20°C, the soaking time needs to be about 100-120 minutes; when the temperature is above 20°C but below 30°C, the soaking time needs to be 60-90 minutes; and when the temperature is above 30°C, the soaking time only needs to be 30-35 minutes.
3. Promoting Germination
After soaking, remove the seeds from the solution, rinse them several times with clean water, and after draining off the water, place them in a container and cover them with a damp cloth to promote germination. Under suitable temperatures and with plump, mature seeds, most plants will generally germinate within a week, and full emergence can be achieved 2-3 days after sowing. In this way, emergence can be 6-8 days earlier than with conventional sowing.
4. Precautions
Before soaking the seeds in hydrogen peroxide solution, the spinach seeds need to be exposed to the sun on a sunny day for 4-6 hours, while removing debris and undersized seeds. In addition, the germinated seeds should be sterilized using a chlorothalonil solution, and the treated seeds should be sown immediately.
The above is an introduction to what to do if spinach seeds have a low emergence rate. We hope it can help you. To learn more related knowledge, please stay tuned to us.
