1. Spinach introduction:

1. Why should spinach be blanched?

Spinach to scald water because it contains oxalic acid, when oxalic acid on the surface of the teeth, because the teeth contain calcium, will react with it, so there will be a sense of astringency. When eating spinach, you can put it in boiling water for a few minutes, and then mix it with sesame oil, which can not only remove oxalic acid, but also retain the nutrition of spinach.

Why is spinach called spinach?

Spinach was originally called Persian grass, because it was introduced into China from Persia (present-day Iran), so it is called spinach. Spinach originated from Persia in western Asia 2000 years ago, and spread from Moors to Western Europe, Spain and other countries through North Africa. Tang Huiyao clearly recorded that spinach seeds were introduced into China from Nepal as a tribute during the period of Emperor Taizong of the Tang Dynasty.

When is the best time to sow spinach seeds?

The main results are as follows: 1. The sowing time of spring mackerel rapeseed: when the temperature rises above 5 degrees after the beginning of spring, it is appropriate to sow in March and harvest 30-50 days after sowing. Varieties should choose late round leaves with late bolting and hypertrophic leaves, large leaves in spring and autumn, round leaves in Shenyang, round leaves in Liaoning and so on.

2. Sowing time of summer spinach seeds: summer spinach is often sown in stages from May to July and harvested one after another from late June to mid-September. Huabo No. 1 with strong heat resistance, rapid growth and not easy bolting should be selected, such as Huabo 1, big leaves in spring and autumn, Guangdong round leaves and so on.

3. Autumn spinach seed sowing time: autumn spinach is generally sown from August to September, and can be harvested in batches 30-50 days after sowing. It is appropriate to choose early-maturing varieties with high heat tolerance and fast growth, such as Lutougu, Huacheng No. 1, Guangdong round leaves, spring and autumn leaves and so on.

4. Sowing time of overwintering spinach seeds: overwintering spinach is usually sown from mid-October to early November and harvested in batches before and after the Spring Festival. It is appropriate to select mid-and late-maturing varieties with strong winter, late bolting and strong cold tolerance. Such as round leaf, late round leaf, Huaye 1, Liaoning round leaf, and so on.

Third, how to grow spinach?

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 side. 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.

Generally speaking, spinach seeds can be planted all year round. Before planting, the seeds can be soaked and germinated, then sowed into the soil after growing white tips, and then transplanted to the field after growing seedlings.
