How to choose spinach seeds? What are the ways of raising seedlings?

Spinach is very popular because of its rich nutrition and various eating methods. Vegetables are grown in many areas. the first thing to do is to choose seeds before planting vegetables, so how to choose spinach seeds? What are the ways of raising seedlings? Let's learn about it.

How to choose spinach seeds?

When selecting seeds, we should not only pay attention to the selection of suitable varieties, but also pay attention to the source of seeds. It is best to select the seeds collected from the seeds sown in autumn and overwintering in the first year, so that the cold resistance of the plant can be continuously improved and can survive the winter safely. The bolting rate was low in the second year.

If the seeds collected by spring sowing are used for sowing in successive years, the cold resistance of its offspring will gradually decrease, and the bolting period will gradually advance, thus affecting the yield and quality of overwintering spinach. Finally, it is added that spinach is a dioecious crop. During the fertilization process, the pollen of the stamens of the male plant must be blown off on the pistil stigma of the female plant so that the female plant can bear seeds, so spinach should be extra careful when keeping seeds.

Seedling raising method of spinach seed

1. Seed drying

The spinach seeds can be dried in the sun for 5-6 hours. In the process of drying, the germs attached to the seed surface can be killed and the occurrence of spinach diseases can be reduced.

2. Seed soaking

When drying spinach seeds, you can adjust the solution to soak the seeds. The seed soaking solution is a mixture of hydrogen oxide and water, and the ratio of hydrogen oxide to water is 1:4. After adjusting the seed soaking solution, the dried spinach seeds can be slowly poured into the solution and stirred one by one. In this way, spinach seeds can be evenly stained with seed soaking solution, which is beneficial to the absorption of spinach seeds. Seed soaking time is related to temperature. Generally, when the temperature is below 20 degrees, the seed soaking time should be about 2 hours. When the seed soaking temperature is between 20 and 30 degrees, the seed soaking time can be reduced by half an hour, that is, one and a half hours.

3. Main points of budding.

After the spinach seeds are removed from the seed soaking solution, they should not be germinated immediately, but should be rinsed several times in clean water, washed off the solution attached to the seed surface, and then put into wet gauze for germination. The temperature of budding should not be too high, the best temperature for budding is 15-20 degrees, and put it in a ventilated and humid place for sprouting. In order to make spinach seeds sprout faster, spinach seeds should be sprayed with water in the morning and evening. Generally, 3-5 days later, spinach seeds will appear white tips one after another.

4. Planting method

As soon as the spinach seed emerges from the white tip, it should be planted immediately. The best growth temperature of spinach seeds is 15-20 degrees. When the temperature increases, the germination rate of the seeds will also decrease. In order to avoid spinach sprouting, sufficient bottom water must be poured before planting spinach. Before spinach emergence, it can also be covered with straw, wheat straw and other mulch to reduce soil water evaporation and avoid direct sunlight on the soil to increase the ground temperature. The mulch of spinach can be lifted when more than half of the spinach sprouts.

The above is about spinach seed selection and seedling methods introduced, in order to effectively improve the emergence rate of spinach, these methods and techniques must be clearly mastered, do you have anything to add about spinach?
