Hey friends! Let's talk about the time of green onion sowing today. Green onions, although the environmental requirements are not too picky, but the sowing time is selected, it is related to the emergence and growth of the back!
The best time to sow green onions is generally in autumn. Why? Because the temperature in autumn is neither hot nor cold, it is suitable for the germination and growth of green onion seeds. But this autumn sowing can't be casual, too early or too late.
If it's early, the temperature is still high, and the green onions are easy to sprout in advance and become sheep's horns, not to mention the low yield, and it will delay things. If it's late, the seedlings are too weak before winter, and when it's cold in winter, maybe they'll freeze to death! Generally speaking, it is better to sow seeds in September and October, so that transplanting in the spring of the next year will yield large and good green onions in autumn and winter!
Methods to improve the emergence rate of green onions
Next, let's talk about how to improve the emergence rate of green onions. That's a lot of tricks!
1. Choose the right breed
First of all, you have to choose a good variety. It is necessary to have a variety that is hardy, resistant to pests and diseases, not easy to sprout, and has a high yield. For example, some varieties such as "Super Green Onion King" and "Cold Resistant Champion Green Onion" are quite good, suitable for our local climate and market demand.
2. Handle the seeds
Seeds also have to be taken care of. Wind-select the seeds, pick the plump ones, and then dry them a little to break the dormancy and make the seeds more vigorous.
3. Pre-sowing germination
In order for the seeds to germinate faster, they can be primed first. Soak the seeds in warm water, stir and soak for a few more hours. Then wrap it in gauze and place it at 18 to 23 degrees to germinate, and when most of the seeds are white, you can sow them.
4. Sowing method
There is also a point of attention when sowing seeds. You can mix the seeds with fine sand so that they are sown more evenly. The sowing depth is about 1.5 cm. If the temperature is high on a sunny day, remember to put a shade net on the nursery bed. Before sowing, the bottom water should be fully watered, and in dry years, small ditches should be opened to water before sowing.
In short, the sowing time of green onions should be selected correctly, and the method of improving the emergence rate should be mastered. In this way, we can grow a lot of good green onions!
I hope everyone can grow great green onions and harvest a lot!
