Where can I sell sweet seeds? What are the methods of raising seedlings?

Sweet violet is a kind of common herb plant with root, which has the effect of clearing heat and detoxifying, cooling blood and detumescence. In recent years, with the expansion of planting area, the output has also increased significantly. Sweet viola is generally harvested 4-5 crops a year, about one harvest in January. So how should sweet potatoes be grown? Let's take a look at its seed selection and breeding skills.

Where does sweet violet seed have sell?

The seeds of sweet violet are relatively small, and once the fruit matures, the seeds will automatically pop up, so be sure to harvest before the seeds mature and the seeds turn yellow, and then dry them. At present, sweet viola is mainly distributed in Northeast China, North China, Shaanxi, Gansu, Shandong, Jiangsu, Hubei, Hunan and other places. In addition to these large-scale production areas, seeds are generally sold, and you can also buy them online.

What are the breeding methods?

1. Preparation before sowing

The conventional seeding box can also adopt seedling tray. Wooden boxes must be soaked with water before use, otherwise it is easy to cause separation between soil and box, affecting seedling emergence. Bed soil preparation generally uses 2 parts of garden soil, 2 parts of moldy soil, 1 part of fine sand, sieved with a sieve with an aperture of less than 1cm for later use. Soil disinfection should be carried out before sowing, which has achieved the purpose of cultivating strong seedlings and preventing diseases and insect pests at seedling stage.

2. Sowing method

The collected seeds are stored in a ventilated dry place. The seeds were sown in the greenhouse at 2~8℃ in the first ten days of December, germinated in February of the following year, and planted in March. The seeds can also be harvested in May and sown directly, and they can germinate very quickly. Because the seeds are relatively small, it is better to use the "basin bottom immersion method" when sowing, that is, to put the bed soil into the seedling tray or shallow basin, wet the whole bed soil, and then sow.

3. Seedling management

Management should be strengthened after seedling emergence, especially to control the temperature to prevent excessive growth of seedlings. At this time, the light should be sufficient, the temperature should be controlled at 15℃ during the day and 8℃~10℃ at night, and the soil should be kept slightly dry. When the seedlings grow out of the first true leaf, they begin to divide seedlings. When transplanting seedlings, the root system should be extended and the bottom water should be irrigated thoroughly. In addition, proper amount of decomposed organic fertilizer can be applied to promote the growth of seedlings. When the seedlings grow to more than 5 leaves, they can be planted.

4. Planting

Planting density: 40 plants/m if medium and large seedlings with leaves between 15 and 20 are selected for transplanting. If medium seedlings with leaves between 5 and 10 are selected for transplanting, the density can be 50 plants/m. In addition, it was found that soil transplantation was faster than bare root transplantation, and the survival rate was higher.

5. Post-seedling management

General growth period without special management, can be in its growth season, every 7 to 10 days topdressing organic fertilizer. It makes the landscape look even better.

In general, there are many classifications of Viola, and sweet Viola is only one of the small species, the market demand is not large, but its medicinal value is really good. When planting, you can collect seeds or buy seeds for seedling cultivation.
