How to improve the emergence rate of autumn spinach

Spinach is a common vegetable with strong adaptability and can be planted all the year round, but because spinach has a hard shell and is not easy to absorb water, it is difficult to sprout, so the emergence rate of spinach is low. And now is the time to plant autumn spinach, so how to improve the emergence rate of spinach? Let's get to know it with the editor.

1. Seed selection

In order to prevent spinach from being infected with diseases during its growth, the unfull seeds of spinach can be picked out before planting and exposed to the sun for 4-6 hours, and then sterilized with fungicides after exposure, which can effectively reduce the occurrence of spinach diseases in the seedling stage.

2. Soaking seeds

There is a layer of gum on the surface of spinach planting, and if it is treated before sowing, the seeds preserved by gum can not fully absorb the water in the soil, which makes it difficult for spinach seeds to sprout, so the seeds need to be germinated before sowing. Spinach seeds can be soaked with hydrogen oxide, spinach planting will be soaked in hydrogen oxide solution and water 1:4 ratio solution, in order to make the seeds more fully absorb water, you can pour while stirring. The soaking time can be determined according to the local temperature, when the temperature is about 25 degrees, the soaking time is about 1 hour, and the temperature is 20 degrees, the soaking time can be extended to 2 hours.

3. Budding treatment

Spinach seeds should be germinated after soaking. After being fished out, the seeds are washed in clean water and then filtered dry. The seeds are wrapped in a wet sandcloth and placed in a cool, moist and ventilated place to accelerate germination. In order to keep the spinach seeds in a moist state, it is necessary to spray water on the gauze sooner or later when sprouting. In general, when the temperature is suitable, the spinach will grow white tip after 2-3 days, and then it can be planted.

4. Planting management

Before spinach sowing, the planted land needs to be watered thoroughly, and then the spinach seeds are evenly scattered on the soil and covered with a thin soil. when the sun is strong at noon, it is very easy to dry the soil, thus affecting the emergence rate of spinach, so in order to ensure the emergence rate, you can cover a layer of straw after sowing and water it in the morning and evening to inhibit the growth of two true leaves.
