"Growing Plants" Plant Growth PPT Courseware

Dwarf sunflowers are sunflowers introduced from abroad. They are suitable for planting in flower beds. The general plant height is 40 cm, the diameter of the flower disc is 3 cm, the main stem blooms, and it has strong adaptability. Generally, seedlings are transplanted. The seedling age is 25-30 days, and the spacing between rows is 40×60. Centimeter, it can also be used as a potted plant for viewing. It can be sown indoors at home in all seasons and can be planted everywhere.

Growth habits: (Dwarf sunflowers like full sunshine and warm environment, but are intolerant of shade and cold.)

Beauty Sakura likes sunshine but is intolerant of shade. It is relatively cold-tolerant, has poor shade tolerance and is not drought-tolerant. It is mostly cultivated as an annual grass flower in the north and can bloom normally in hot summer. Grows in full sun, loose, fertile soil, and blooms luxuriantly.

watering

Because the root system of Belle Sakura is shallow, watering should be paid attention to in summer to prevent drought.

Too much or too little water during the maintenance period is not conducive to growth. Too much water will lead to thin and leggy stems and reduced flowering; lack of water will cause poor plant growth and early fruiting.

Wet wipes germination

1. Pour water, just wet the paper towel, not too much.

2. Put in seeds, here are flower seeds and gourd seeds.

3. Cover it with a film to moisturize, insulate and create a small greenhouse.

4. It’s exposed, that’s the root.

Transplant it into a small flowerpot, with the sprouts facing downward (those are the roots)

2. The process of germination of wet wipes:

A: Sun-sown seeds. Generally, seeds should be sun-sown (rather than exposed to the sun) before sowing to increase the vitality of the seeds and increase the germination rate and germination potential. Germination rate refers to the proportion of seeds that can germinate, and germination potential refers to the proportion of germination per unit time.

B: Soaking seeds. Professionally, seeds with hard shells need to be soaked. For others, seed soaking is not necessarily required. Soaking time is 3-6 hours.

C: Germination: Families recommend using a transparent cup, soaking a layer of paper towels and spreading it on the bottom of the cup, placing the seeds evenly on top of the paper towels, and then placing a layer of soaked paper towels. Then seal the mouth of the cup with plastic paper.

Then wait for germination. (Germination time varies from 1 day to 15 days)

3. Things to note during the germination process:

A: Temperature

Pay attention to keeping the temperature at a suitable temperature

B: Humidity

Be sure to keep the paper towel moist until germination occurs, i.e. keep the seeds moist for germination.

C：Other

Transplant the seeds as soon as possible after they germinate to avoid damaging the root system.
