Describe in detail the culture method of lotus flower _ how to make a healthy and beautiful lotus flower

How to grow purse flowers? Purse flowers are not only afraid of cold, but also afraid of heat, dry and wet, like the sun and withstand shade, and avoid direct sunlight at the same time, so it is more difficult to cultivate grass flowers. Let's introduce the breeding method of lotus bag.

1. Requirements for soil

Sandy loam with loose, good air permeability and unobstructed drainage, plus a small amount of bone powder as base fertilizer, should be disinfected at high temperature before use.

2. Temperature requirement

The optimum temperature for lotus flower growth is about 15 ℃, and when it is higher than 20 ℃, it has an effect on growth, budding and flowering. If the temperature is reduced to about 10 ℃ during flowering, the flowering period can be prolonged. However, the night temperature and overwintering temperature during the growing period should not be lower than 10 ℃.

3. Lighting conditions

Like the light, avoid the scorching sun. When the light is too strong at noon, it should be properly shaded and well ventilated, otherwise it is easy to cause cataplexy disease; increasing the light time can blossom ahead of time, such as adding 3 hours of light a day in November and blooming at the end of January of the following year; greenhouse cultivation should pay attention to 30% shade before October, no shade from October to March of the following year, and about 50% shade during flowering after March.

4. Requirements for moisture

Drought will cause poor plant growth, must pay attention to drainage, too wet and easy to cause root rot, watering should not stain the leaves, because the leaves are hairy, easy to rot leaves, require watering to see dry and wet, can often sprinkle water around the flowerpot, keep the air humidity above 80%, but pay attention to the flowering period can not spray water on the flowers, so as not to affect fruiting.

5. Requirements for fertilizer

Like fertilizer, but should not be too thick, apply thin retting cooked cake fertilizer or hoof horn liquid fertilizer every half a month; avoid contamination of leaves by fertilizer and water, which can make flowers bloom and flourish; if you find that stems and leaves grow too long, you should immediately stop fertilization; when changing pots, mix an appropriate amount of mature fertilizer in the culture soil; when the scape appears, add 1% superphosphate solution twice to make the flower color more bright.

6. Pollination requirements

It is difficult for lotus to pollinate naturally, so seed collection should be carried out at the beginning of flowering, selection and hybridization should be carried out consciously, and generally in the morning, the Corolla can be cut off after pollination, at the same time, shading and ventilation should be strengthened to avoid direct sunlight, and the pot soil should be kept a little dry, which can improve the seed setting rate and obtain fuller seeds.

7. Methods of reproduction

The propagation of lotus flower is generally carried out by sowing method, which is carried out at the end of August and the beginning of September when the weather is cool. If it is too early and hot, the plant will be small, which will affect the flowering of the next spring. Sowing should be done with a mixture of decayed leaf soil and fine sand after sowing, covering the seeds with a layer of fine sand, watering the seeds with soaking pot method after sowing, covering the basin with glass, placing in shade, and keeping about 20 ℃, about half a month. Remove the glass 3-5 days after emergence, place the ventilated and visible place, and the time seedling, the temperature drops to 15 ℃, the basin soil must not be too dry or too wet, pay attention to increase the air humidity, wait for 2-3 true leaves to grow, plant in a small pot, when there are 8 leaves from November to December, single plant can be planted in a large pot, requiring room temperature 8 ℃-12 ℃, and flowering from February to April the following year.

Through the above introduction, we must have an understanding of the breeding methods of lotus bags, friends who want to cultivate lotus bags, hope that the above methods can help you!
