Seed planting method of Scutellaria barbata / sunflower

Sunflower also has pine leaf peony, Scutellaria barbata and other aliases, belongs to Portulaca oleraceae, the scientific name is Portulaca oleracea. It is a recommended Bensheng plant, growing close to the ground, with a seedling height of no more than 10 cm, so it is very suitable for families to grow flowers in the courtyard, and has been widely planted as a small potted plant in recent years.

1. Prepare basin soil

Although "barren tolerance" is one of the characteristics of sunflower, its growth does not care about the quality of the soil, but as a flower grower always expects flowers to grow strong roots, numerous leaves, and colorful flowers, so it is better to prepare a loose, breathable and fertile soil as much as possible.

During this period, oily foods that are out of date at home, such as sesame powder, soybean dregs from self-milled soy milk (let them ferment), or fish intestines (fermented in advance) can be used as base fertilizer.

2. Sowing seeds

At the end of April and early May, the climatic conditions in the south of the Yangtze River are the most suitable for sowing. Before and after a month and a half of the growth period, it can be described as rapid growth and rapid growth, during which the secret lies in sowing this link.

In order to make the seeds come into close contact with the soil, sunflower seeds can be planted evenly on the surface of the fine-grained basin soil and then covered with a thin layer of fine soil.

3. Raising seedlings

It is very important to ensure that the seedlings survive the extraordinary period safe and sound. Be patient enough to take care of them, just like treating babies in swaddling clothes. If you don't pay attention to them, the seedlings will die young, and the seedling rate will be greatly reduced.

4. Interseedling and transplanting

Inter-seedling is also called plucking seedling, which is to keep a certain distance between seedling and seedling. Choose a pair of sharp-nosed tweezers for Miao tools. When the seedlings grow a few millimeters high, they can begin to grow. Adopt the method of batching and time-sharing, always remove the relatively thin ones and leave the sturdy ones until there is still a gap of three or four centimeters between the seedlings.

5. Take off the head

When the seedlings grow to 3 or 4 cm high, branches grow again from the roots. At this time, take off the tip of the main branch, and soon a cluster of branches will sprout at the break. When the branch of the root grows to a certain length, the branch can also be decapitated. After this treatment, the sunflower is dwarfed and the plant type becomes more beautiful.

6. Irrigation

At the seedling stage, the weather is not very hot, and the moisture evaporates slowly, so it is not suitable to irrigate too much. When the flowering period is in three days, it needs to be watered thoroughly and fully absorbed.

7. Seed harvesting

The mature sunflower seed is silver gray, but it is difficult to harvest it at the right time. The seed clip is either cracked or the seed is gone. So always touch those yellow seed shells with your hands, the seed shells that fall off as soon as you touch them are the best; you can't touch them, but the shell is yellow and white, so take it off and pinch it with your two fingers to reveal the blackened seeds. this is because it is still a little damp, and after a while, the black seed becomes silver gray seed.
