How to plant the seeds of Yu beauty?

Yumei flowers and plants of the same genus are taproot, few whisker roots, and are not resistant to transplantation, so direct seeding is usually used for 2-year-old cultivation. If it is needed for garden layout, it is best to use a nutrition bowl or small paper pot to raise seedlings, even bowls or pots. Otherwise, it is difficult to survive or grow poorly, so let's take a look at how Yu Mei seeds are planted.

Sowing time

The seeds of Yumei can be sown in spring and autumn. in general, spring sowing is from March to April, florescence is from June to July, autumn sowing is from September to November, and florescence is from May to June of the following year. In order to collect seeds, it is best to sow in autumn. In North China, because of the severe cold in winter, it is difficult for seedlings to survive the winter, so the direct seeding of "Lesser Snow" in early winter is often used, so that it can germinate and grow as soon as possible in spring.

Sowing method

Yu beauty sows the soil to clean up, make the border to water thoroughly, and then sow or sow. Because the seeds of Yu Mei are small, the soil should be leveled and beaten fine when sowing, and it is not necessary to cover the soil after sowing, but can also be covered with a thin layer of fine sand. The thickness of the covered soil should not be seen (0.2-0.3 cm). The suitable temperature for seed germination is 20 ℃, and the family can live in the flowerpot.

Seedling management

The main results are as follows: 1. The first stage: the first stage of Yumei seed seedling is from sowing to radicle appearance, when the germination temperature is 18-21 ℃, it takes 5-7 days, and the substrate should be moderately moist.

2. The second stage: the second stage is from the emergence of radicle to the extension of cotyledons, the completion of germination, and the growth of a true leaf. In this stage, the temperature is 1820 ℃, fertilization can be applied once a week, N:P:K is used alternately at 15:0:15 and 20:10:20, and the concentration is 50~75ppm. It takes 7 days, and the substrate remains dry.

3. The third stage: the third stage is the emergence and growth of a true leaf, which meets the transplanting standard. The temperature of this stage is 17 ℃, the concentration of fertilizer is 100~150ppm, and it takes 21 days to fertilize once a week.

4. The fourth stage: the fourth stage of Yumei seed breeding is to prepare for transportation, transplanting or storage and transportation. the temperature of this stage is 15-17 ℃, which takes 7 days, and the fertilization concentration is the same as that of the third stage. After that, it can be put on a 12 × 12 cm basin.
